What factors affect the distance travelled by a margarine tub

Aim: My aim is to find out how the distance travelled by a margarine tub is affected by the force applied on it.

Prediction: I predict that the greater the force applied, the further the margarine tub will travel. This will happen because when the elastic band is released, the force exerted by the band will make the forces unbalanced and the resultant force will make the margarine tub accelerate. But however great the force I apply is, the margarine tub will eventually stop. This happens due to air resistance and friction; “friction is a very common force. Whenever one object slides over another (in this case, a margarine tub over a floor) friction tries to stop the movement” – Johnson, 2001.

I also predict that as the distance travelled increases, when I repeat the experiment there will be a variety of results collected.

So, I predict that the further back I pull the Newton meter, increasing the force, the further the margarine tub will travel.

Equipment:

Method: To set up the experiment we will tie the elastic band around the legs of the chair, making a sling-shot type mechanism. We will then attach the Newton meter to the elastic band. When the meter is pulled back to a certain force (measured in Newton’s) and release it, the ...
