An Investigation into the Factors That Affect the Distance Travelled By

Projected Margarine Tub.

Aim

There are many factors that effect the distance travelled by a projected margarine tub, the three main factors being:

  • The mass of the margarine tub.
  • The type of surface where the margarine tub will be projected.
  • The amount of energy given (potential energy)

For this investigation I am going to find out how changing the mass of the margarine tub affects the distance in which it is projected.

Prediction

I predict the greater the masses of the margarine tub, the shorter the distance it will travel. This is because as the mass increases, the frictional force is greater.  This means that there is a greater pressure between the tub and the floor.  The higher the pressure is the greater the amount of heat produced due to friction.  This heat is lost quickly and so the tub travels a shorter distance.  Whenever energy is transferred a force moves.  If the force and the pull back distance remain constant and the mass of the tub is doubled, the distance travelled by the tub is halved.  As the elastic potential energy is converted to kinetic energy that is converted further into heat energy.

Conclusion

If the experiment was to be repeated, I would not use just stools as we found out that they kept slipping because they were too light.  Therefore, I would suggest using stools again but have a person sitting on each stool to make sure it wouldn't move.  If this was to be done, you would have to make sure that the people who were sitting on the stool are of similar weights too make sure it remains a fair test.

Also I think when the tub was being pulled back each time, you have to ensure that before projecting the tub that each time it was being pulled back to the full 10N/10cm.

.  

In our experiment we had a few anomalous results (as highlighted).  This could be due to the following reasons:

  • 50g masses were too light
  • The stool sometimes moved
  • Fingers can get in the way when the stool is being projected.
  • It may not have always been projected to the full 10N/10cm each time.
  • Although string was used to reduce parallax, there may have been an inaccuracy when measuring the distance.

 I think it would also be beneficial to do more repeats to allow for all the anomalous results.

    I took out the anomaly from my table and then calculated the average of 50g using the first two results of the 50g experiment. I then plotted another graph, but this time without the anomaly: The trend in the graph shows that as the mass of the margarine tub increases, the distance travelled by the tub decreases.
