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.

    Definitions Gravity Force , Fgrav The force of gravity is the force at which the earth, moon, or other massively large object attracts another object towards itself. By definition, this is the weight of the object. All objects upon earth experience a force of gravity which is directed "downward" towards the center of the earth.

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

    This shall provide a reference point to compare against after the ball is dropped. The setsquare shall then be held square against the ruler at the required height for the drop. (The right-angled setsquare is being used to avoid parallax error in the measuring of the heights from the sand and the point the ball is being dropped from.)

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

    This is achieved by making a small hole in the centre of the parachute, which lets the air escape. Apparatus * Stop clock * Plastic for parachute * Plasticine * Strings * Measuring tape Method First of all, the metre ruler should be used to measure the height of the area being used (in this case the stairs).

    I will have 10g as the dropping weight 2. I will start recording on Insight Timing, and let the weight drop, making the trolley and, more importantly, the piece of card move. 3. I will make sure someone catches the trolley before it falls off (see safety) 4. I will stop insight timing and move the trolley back to the start position 5.

  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.
