Investigating a Factor that Affects the Rate of Decent of a Parachute Aim- To investigate one factor that affects the rate of decent of a parachute. Plan There are many factors that affect the rate of decent of a parachute, some of these are: The weight of the object on the end of a parachute, the weight of the parachute, the length of the strings on the end of the parachute, the surface area of the parachute, and the shape of the parachute. As we were only instructed to investigate one of the factors listed above we chose to find out how the surface area of a parachute affects it's fall.This is how we are going to carry out our experiment: Firstly we will cut out 8 differently…show more content…
We will use sellotape to attach the string to the corners of the parachutes, we must be carefull to put the sellotape on flat so that the binliner doesn't ruckle and turn the parachute into a funny shape so it affects the results.We measured both the parachutes and the strings using a meter ruler. Thirdly we will attach a lump of plasticine to the ends of the strings of each parachute. The lump of plasticine must be put on at exactly the same point on the strings on each parachute so that the out come isn't affected by the parachutes being pulled down awkwardly or the strings being longer/shorter so that the parachute touches down quicker/slower. The plasticine should also be exactly the same mass (5grams) for each parachute because if there is more weight on some of the parachutes those parachutes will be pulled down faster and if there is less weight on some of the parachutes those parachutes will be pulled down slower. The plasticine must also be stuck at the same point on each of the parachute's strings so that the results aren't affected by the parachute being pulled down awkwardly or the strings don't vary in length. Once all of the parachutes are made we will drop each parachute from the ceiling, which is 2.5m high, and time how long it
