Investigating the effects of forces and acceleration
Aim
To investigate how the size of a parachute effects acceleration of the blutac attached to the parachute.
Information I already know
The bigger the surface area of the parachute the more the air resistance builds up underneath the parachute, which causes it to float gently to the ground.
Safety
To get to a sufficient height I must stand upon a table, to make this experiment safe I will make sure not to fall, as this would cause harm to myself and the people around me.
Apparatus
String
Paper
Blutac
Scissors
Sellotape
Stopwatch
Fair test
To make my experiment fair I will drop the parachute from the same height each time, keep the weight of the blutac the same and place the blutac in the same position on the string each time. If I were to change any of these it would make an error in the results.
