Parachutes Investigation
Aim
The aim of this investigation is to find out how one chosen variable
can affect the rate of descent of a parachute. There are many
different factors that can be taken into consideration and varied to
see what has the best effects on the rate of descent. The options
where:
a) The size of the canopy,
b) The weight pulling on the parachute,
c) The length of the chords,
d) The shape of the canopy
Also the forces acting on the parachute had to be taken into
consideration and appreciated for how they could be influenced or used
to aid the rate of descent.
The forces came in the form of air resistance and gravity.
Procedure
I chose to see what the effects of the weight the parachute had to
support would have on the rate of its descent. My original prediction
after some general thinking was that the heavier the parachute was,
the faster the parachute would descend. I believe this to be totally
true as it is a logical thought process; a feather falls slower than a
hammer indicating heavier objects fall quicker than lighter objects.
Also the aerodynamics matters, if a surface area of a side of a brick
is cut out on a piece of paper and dropped at the same time as the
brick the brick will hit the ground before the paper. This is because
heavier objects fall to the ground quicker than lighter ones.
The next question is why is this important? It matters because if
something is falling to fast or slow then other variables can be
changed to counter act this, e.g. the size of the canopy or the
aerodynamics of the weight. The object that needs to be controlled is
air resistance; this is made higher or lower by parts of the
parachute. The more air resistance created by the canopy then the
slower the parachute will fall. What also matters is how the weight is
distributed from the parachute.
I was at Fort Benning Georgia in August 1988 to attend jump school. I had done my basic training here four years earlier with Sgt. Smith who would be my black hat true instructor for airborne school. I was standing in formation at five in the morning. It was cold now, but Georgia has hot, humid daytime temperatures that were draining mentally and physically for a student from Northern California. I knew I wanted to be here even though there would be physical and mental stresses, challenges and the possibility of serious Injury. The students would be weeded out at every point. I did not want it to happen to me. During my four years in the Army, I learned that I like to be an independent, resourceful, goal oriented problem solver. In the infantry, I had to obey the orders and not think for myself. Uniformity in everything was demanded.

The Terminal Velocity of a Paper Helicopter Introduction. Terminal velocity is the resulting occurance when acceleration and resistance forces are equal. As an example, a freefalling parachutist before the parachute opens reaches terminal velocity at about 120mph, but when the parachute is opened, terminal velocity is reached at 15mph, which is a safe speed to hit the ground at. This experiment will be no different, as I will be examining the terminal velocity of a freefalling paper helicopter.
Pre impact conditions mixed with event specific conditions combined with one another during a disaster produce physical and social impacts to a community. The impact from each disaster can be reduced by interventions through emergency management. By assessing these pre impact conditions, an emergency manager can produce social risks and vulnerabilities within their community. Integrating these social risks and vulnerabilities emergency mangers can use the four most important phases in emergency management: preparedness, planning, response, and recovery to benefit their community as a whole.
I made a cube like structure out of Popsicle sticks that was nice and firm. I cut out the corner of the Ziploc bag and tied it to some string and tied the string to the Popsicle sticks. I took more Popsicle sticks and made edges to hold up the cube. I made my finally touches by making the parachute and putting it on the cube. The parachute was made of a Walmart bag that I cut the handles off of and tied some string to it. I rapped the string around the four sides of the Popsicle sticks. I took

Put together a plan of action to progress the person demonstrating the unskilled movement so that it becomes a skilled movement. This may involve movement cueing, additional resistance training, technique coaching, mobility work, or anything else you deem necessary to address your patient/client’s insufficiencies. Provide a 1-2 page written description of your plan, plus a 3-5 minute YouTube video of yourself coaching someone (friend or relative) through the necessary steps for improvement. You may want to review chest analysis video in week 5’s lab https://youtu.be/kDCIXNb4m3k as an example. In the video, provide an example of how the patient/client previously moved, what you did to address the insufficiencies you noted in CAP 6, and a
Amanda loves to ski, this weekend her parents are taking her on a skiing trip for her 12 birthday. Amanda was walking down stairs when all of a sudden her parents yelled, “ surprise”. Amanda was confused because her birthday is tomorrow. Amanda was walking down the stairs when all of a sudden her parents yelled, “surprise!”. Her parents handed her a gift, it was a snake when Amanda went to go open the gift a snake popped out and she jumped with fear. Today is the skiing trip amanda and her birthday was so excited because it has been a long time since she skied. When they finally got to the perfect mountain Amanda asked her mom if she could take a picture of her coming down the mountain. So as she way coming down the mountain

Flashing lights. Pounding music. Fog covered floors. Rustic coffins. All of this in health class. When I was in fifth grade at Harriet Bishop Elementary School, the fifth grade was required to participate in the jump rope program. The jump rope program was paired with the health unit on healthy living, designed to keep kids active. I loved creating the jump rope program. It was a lot of work to plan, practice, and perform, but it ended up exceeding anyone's expectations.
Have you ever wanted wanted a new phone, or maybe a vacation? There are several privileges that people want, even if they don’t deserve them. Throughout the years I have always wanted a trampoline, as well as my brother. Trampolines are beneficial in many ways for all ages of children for several reasons. They give off exercise, and who wouldn’t want their kids to stay healthy. They come in all different shapes and sizes to fit any space. They’re also several different sales on trampolines always occurring. As a result, a trampoline would give our backyard a more kid-friendly environment.

Skydiving has been around since ancient Chinese times as a form of aerial stunts. Leonardo da Vinci and the Chinese are both credited for creating the parachute, but it was really in the 18th century when France both created it and used it by basically throwing themselves out of planes. Little did anyone know that skydiving would be one of the craziest sports today. Jumping out of a plane two and a half miles up into the sky would not be someone’s idea of a normal day. As bad as two and a half miles up in the sky is, try doing it traveling at a rate of one-hundred and sixty miles per hour with just a parachute to save you. To many people this would be a nightmare; but to some of us, it is the biggest thrill of our lives.
