Prac Report – Investigating Parachutes Experiment Aim: To measure how the size of a parachute t’s surface area affects the parachute’s speed‚ acceleration and time of flight. Hypothesis: A parachute with a larger surface area would fall slower due to that fact there would be a higher level of drag‚ or in other words more air resistance. Materials: * Sturdy garbage bags * Metric ruler * Scissors * Washers * Twist ties * Light-weight string * Stopwatch Method:

Introduction Back in the early 1980’s‚ a man named Gordon Gecko summed it up in 3 words. “Greed is good.” Golden Parachutes are a perfect example of greed in motion. Before the economic collapse of 2009‚ golden parachutes were not something that everyone knew about. The government bailout of the banks and the automotive industry brought them to the forefront of everyone mind. Golden Parachutes‚ by definition‚ are a clause in a contract of a CEO or other executive officer of a corporation‚ which is the

Parachute Experiment Aim: To investigate the effect of surface area on a performance (more the amount of a parachute better the performance) of a parachute. Hypothesis- More the amount of holes in a parachute‚ faster the rate of the fall. Variables: Dependent variable- The time it takes for the parachute to reach the ground. Control variables:Mass > Adding or subtracting mass from the load. > Clay can be molded around the load to increase mass. > Parts of the load can be cut off to decrease the

Assume that the force of air resistance is k1 |v|‚ with k1 = 1.65 kg/s‚ when the parachute is closed and k2 |v|‚ with k2 = 26.4 kg/s‚ when the parachute is open. (a) Find the speed of the sky diver when the parachute opens. (b) Find the distance fallen before the parachute opens. (c) What is the limiting velocity vL after the parachute opens? (d) Determine how long the sky diver is in the air after the parachute opens. (e) Sketch the graph

aircraft from which to jump and a parachute. When you are skydiving‚ you will freefall during the first part of the jump‚ but then you will open your parachute in order to slow your descent to the earth’s surface. Anyone can go bungee jumping without needing to undergo any training since it is up to the operator to ensure that they will be safe. Training is required in order to go skydiving‚ however‚ since the jumper needs to know how and when to open their parachute and how to ensure that they land

Segregation during World War II was at its lowest point in history‚ but one group called the Triple Nickles worked through it and became highly tuned fighting machines‚ never getting to show their worth in the front lines of the war. The African Americans of the 555th trained the same if not more than the regular caucasian paratrooper. Due to segregation of the time period all African Americans were treated worse than prisoners. Then they got a break‚ and felt their calling as smokejumpers out in

The factors that affect the motion of a falling object Scientific Knowledge When an object falls‚ many forces are acted upon it: gravity‚ friction‚ air resistance and‚ if in the water‚ up thrust. When an object starts to fall‚ gravity over powers air resistance‚ however‚ as an object starts to reach terminal velocity (its maximum speed) the opposite forces start to even out until they are equal. Some people believe that if the forces are balanced then the object has stopped moving‚ meanwhile they
