Investigating the effects of forces and acceleration


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.


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.








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.

      If I were to do this experiment again I could improve it by dropping each parachute more than ten times to make my results that more accurate.  

      I could extend my investigating further by making more parachutes and trying different materials.  I could also do an investigation using the same sized parachute but change the weight each time, this would tell me the relationship between the force and the weight.

    The light gate may not have been one hundred percent perpendicular to the picket fence causing a small in accuracy in the results. This is shown in Diagram 4. The wheels on the trolley may have caused some runs to be slow and some to run normally which would severely affect the acceleration when calculated in the results.

    It was discovered in the investigation that it was not possible to use a lighter weight object due to the fact that the crater it made was not of sufficient size for measuring and proved difficult. Yet, it is possible that if there was a way to measure the crater

  1. Things that affect the speed of a falling parachute.

    The first parachute can now be made. A square of plastic should be cut, measured to a surface area of 100cm�, 200cm�, 300cm�, 400cm� or 500cm�. Three small holes should then be cut into the parachute. The holes should be the diameter of the string being used.

  2. I will investigate the change of velocity and acceleration of a laterally moving object ...

    Also After some simplifying, this becomes: a = m2g I (m1 + m2) Therefore, as the mass increases, so will the acceleration. Prediction There are really two predictions to be made. One is on the subject of velocity, the other on acceleration.

  1. Investigate the effects of an asteroid impact on Earth through a small-scale simulation.

    It is this mechanical damage that will cause the effects that I have listed above and could lead to the death of billions of people and animals. I shall be dropping a steel ball into sand to simulate an asteroid collision, because the asteroid would be roughly spherical and have a high density, like the steel ball.

  2. Strength of a string practical investigation

    * Extension: This will change as more masses are added to the string, I will be collecting readings of extension changes until the string snaps. * Force (via. Masses): This variable will be controlled by me, I will add masses to the strings until they snap.

  1. The Area of a Parachute Compared To Its Rate of Descent

    This factor is controlled so that it rises at a constant rate, and it keeps the experiment fair. There are also controlled variables. These variables are ones which do not want to be changed, in order to keep the experiment fair.

  2. To investigate the relationship between the velocity of a parachute and the drag force.

    � Distribution of mass, i.e. perhaps on the parachute itself as opposed to on string attached to the parachute (this of course would not be a continuous variable so it would not be of great value). Apparatus A square of bin liner, thread, sticky tape, plasticene, and weighing scales.
