Chutes, Gravity and Drag

A field of science in Physics states, in Newton’s First law: “An object will stay at rest or continue at constant velocity unless acted on by a resultant force“.

No matter what mass an object is falling towards the Earth, science has found that they will fall at the same rate, if no resistance exists, and land at the same time.

So, how do these forces make skydiving, with a parachute, and science of gravity, chutes and drag – so popular?

Learning the Math of Falling

Calculations is done with use of the equations involving force, mass, and acceleration. Studies have shown that acceleration remains constant, for all matter with mass. This formula shows the most basic equation:

F=mg

The breakdown of this equation refers to the following:

F = force, objects being pulled to the Earth
m = mass of the object
g = acceleration rate due to gravity(g = 9.807 meters per second-squared (m/s2) )

Following mathematical rules will have us write out this formula as:

F= m x g

The use of this formula can get far more complex depending on which area of science, one is using it, such as in aeronautics, space sciences, engineering, etc.

The world of skydiving is a popular sport even though it can be a risk to one’s life. Not many can understand ‘why jump from a perfectly good plane?’ but there are enthusiasts who love the extreme sport of skydiving, or BASE jumping – sports requiring one to jump from a plane or off a fixed object (cliff). These are considered extreme sports and may require a fair investment of funds in gear and equipment since rental for a plane may not be anything to sneeze about.

Forces created in Skydiving

On topic, the meeting and creation of forces, involved with deploying a parachute. A person will jump out of a plane and find themselves falling through the skies, gaining speed along the way, since ‘a force of attraction exists between any two objects that have mass and the more mass they have, the greater the force of attraction. The closer they are, the greater the force of attraction will occur‘. I will hazard a guess that this particular stimulus creates a thrilling excitement not found in other sports, such as volley ball.

A parachute is deployed, and the chute creates a surface area, which slows the descent or rate of acceleration. This surface area creates ‘air resistance or drag force‘. The larger the surface area, the slower the descent. This ‘resistance or drag force‘ creates a force that’s opposite to the force of gravity therefore creating a ‘push and pull‘ force that are nearly equal.

Safety in Chute Deployment

The timing of deploying a parachute is important to note aka ‘pull altitude‘. This is due to a shrinking drag force. As one slows down, the drag force gets smaller even if the surface area of air resistance, is larger than one’s weight.

Also important is speed of the chute itself opening, therefore a deploying sequence with equipment is used, to prevent injuries, death or damage to the parachute. This helps to slow deployment of the main ‘canopy‘ along with maintaining a tangle-free ‘chute opening‘. Most skydivers will jump at about 12,500 feet above ground level, allowing for one minute of ‘free falling‘ before deploying their parachute, a minimum of 2000-2500 feet for the more experienced.

Differences between Skydiving and BASE Jumping

The gear and equipment for skydivers and BASE jumpers are NOT the same. BASE jumper gear is designed to deploy quicker and at slower air speeds. BASE jumpers do not have ‘reserve‘ chutes either as the skydivers equipment does. The science involved in these sports may be the same but both are definitely activities, not for the ‘faint hearted‘. Is this where I say being a sports spectator is safe?

Conversations to teach Civic Engagement

Conversations start here
Conversations start here

It’s amazing how one little conversation can change things forever.

Conversation is the ‘exchange of thoughts through informal talking‘, together, but there is also the other quote, ‘talking to oneself‘.

Speaking about ‘civic engagement‘ refers to talking and working as a group (use of collective power) to bring about change in public issues of concern.

Either way, it’s to examine or share, a topic of interest. Discussing a specific topic can lead to learning various outcomes and who’s best for what task.

Discussing Civics with your Family

Meeting at the table has been a favored gathering point and event for family and friends. Conversation can be considered the ‘toast of the party’! Would you agree?

Civics refers to the duties, rights and privileges of citizens. Parents can introduce this topic during evening dinner meals, and discuss with their children, just what is and what isn’t allowed since society has it’s norms, rules and laws, along with the consequences.

Children can learn from these discussions and hopefully, avoid glamorizing or considering, criminal behaviors or acts. It’s preferable to begin with asking questions, to measure the amount of knowledge and starting point versus entering preach or lecture mode.

Learning gets Shared

Parents take on many roles for their children, and one is, as a teacher. Helping children understand their place in society, will help towards developing the child’s personal and intellectual growth.

In turn, they will be able to pass on these lessons learned at home, to their friends. They will also be learning the beginning steps of civic ‘engagement‘. The ability to discuss, as individuals yet act as a collective group, to achieve or address, public concerns.

Parent and child conversations can help develop a child’s intellect and learning to use reason, gain understanding and separate, real from the imaginary, and ground the ego. After all, society works together to uphold their norms, rules, regulations and laws, to function as a nation, and remain in a state of peace, with each other. A child learning this knowledge and skills can develop into a socially well -adjusted adult.

Short on Energy or Time

A few parents may find, they do not spend or make for, any quality time with their children other than giving directions and reinforcing rules. This can be detrimental for both parent and child along with making for a bad day.

Socially maladjusted children can usually be observed as those with behaviors and values that conflict with society norms. Abuse and neglect can have lifelong consequences on a child, which can easily be observed by trained education, and mental health professionals. Local laws may require any suspicions of child abuse and neglect, to be reported.

The idea of teaching a child about rights and responsibilities of adults, and children may be daunting for parents. This can be resolved by taking time, to research the subject online, or visiting the library.

Importance of Open minds, Patience and a Safe environment

A conversation with our child is a two or more person orchestra vs a one-sided conversation, allow for all to contribute. It takes skill to shape and guide a conversation to create meaning, learning and thinking. We can’t forget a dose of humor can lighten a conversation and add fun.

A meaningful conversation in a family can take place when trust and safety exists. Let your next dinner conversation be a learning experience for your children. There are many topics to choose but one should first start with their place in society. One may be influencing a future leader.

Why find Poverty in Canada?

why find PovertyThe economy of one’s nation depends on the decision and flow, of what types of goods and services to offer, how they are created, and who is the market.

Economic problems are faced by many societies around the globe but even the ‘wealthier’ nations face poverty. We see or hear people tumbling from high salary jobs to work in minimum wage positions, or none. So, why find Poverty in Canada?

Exploring Government Policies

 The exploration begins with examining government policies and business. Consumer sovereignty refers to how price movements provide signals for profiting off goods. Low or falling price goods are limited and high or rising price goods, are increased.  Almost sounds like ‘money gouging‘ of the people, yes?

hi buy = hi price = profits

It’s believed that the pursuit of one’s own interests will serve the interests of all. This only serves those who can afford the higher price goods and leaves a number behind, unable to purchase these same goods. An inequality and gap is created and political conservatives believe that the poor create their own plight.

Poverty is defined as ‘the condition of not having enough income to maintain a standard of living regarded as normal in a community‘ (Gage Canadian dictionary). As we know, income refers to the amount of money one receives.

Employment Policy and Unemployment

People exchange their labor and skills for pay which once disrupted, can bring huge changes to self and family’s over all, change their quality of living standards, regardless of education and skills. Take a pause and ask, who truly benefits with this action?

homeless-want-work

The employment policy in Canada relies on their fiscal, monetary and trade policies. When the government spends less than it receives this causes economic activity to decline.  Unfortunately, lowering the national debt also becomes a main concern, that must also be resolved. Definitions of these policies are as follows:

    • Monetary policies, refers to altering the nation’s level of interest rates and money supply. Low interest rates is used to encourage business investments, economic growth and an increase in money supply makes loans easier to obtain.

    • Fiscal policies refers to how government uses their powers of taxation, spending and borrowing to stimulate or dampen the nation’s economy.

    • Trade policy, used by federal and provincial government, they promote Canadian exports with the goals of job creation and increased income.

    • Employment policy is the use of all the above policies but includes tools such as incentives in tax investments, capital gains exemptions and government grants for retraining.

The management of these policies and tools available to the government will indicate their creativity or lack of, to move or limit the nation’s economic activity. Whatever goes on at the top trickles down, so if there’s help for business owners to operate, train and prosper, jobs can get created and/or maintained. Still, there’s also zero consequences when businesses spend those monies elsewhere (i.e., CEO bonus’s)

only good govt helps builds jobs

Today, Canada ‘s government has implemented corporate tax cuts that have gone from 21% (2006) to 15% (2012) and jobs continue to be outsourced. How does this help build employment for Canadians? Well, the Conservative government states benefits will occur, about ten years later. Job growth in Canada was in reality, less, due to  job growth in other nations.

Follow the Government $$ Cuts

Corporations are benefiting with record tax savings AND pulling the Canadian employment growth down. (Behind the Numbers, 2011 (PDF), by Canadian Centre for Policy Alternatives). Further funding cuts to ‘balance the budget‘ were FROM various social programs that had helped towards building and/or improving Canadians quality living standards. This practice has monies going from the people to the government.

Poverty can be found at various levels in society. A few factors that contribute to poverty can be on those that live in remote areas with little or low job opportunities, low natural resources/agriculture potential, and politically disadvantaged groups.

Unfortunately, Canada has a huge land mass with scattered communities not receiving and/or accessing equal services, compared to the larger urban cities. It’s difficult to cheer on the Canadian government participating in reducing global poverty, when Canadian citizens are living in poverty.

sayNOtoPoverty

The holidays arrive and pass, days blur one into the other and survival is the priority of the day. While politicians sit home in security and comfort, ready for the holidays, many Canadians in poverty, are walking along, shivering in the cold, seeking their next shelter for the night. A parent stands in line at the local food bank, youths think about crime vs jail, children depending on their parents.

The experience, levels and journeys of poverty may be new for one yet a constant companion for others. Maybe, the next election will bring a new government and change the status, maybe a more Humane government will step up.

Canadians Wealth Gap

For now, those in poverty today ; food, shelter and safety are their priorities. How did the ancient Mayans manage to feed and house their WHOLE population (1491-New Revelations of the Americas before Columbus)? Do you help those living in poverty? What do you think can help bring change? Let us know!
