Physics Investigation A Formula 1 Margarine Tub
Aim:
I am going to investigate how the mass of a margarine tub affects the distance it can travel.
The following Factors will affect the distance the tub can travel:
· Surface area of the tub
· Air Resistance
· Force applied to propel tub
· Length of elastic bands used to propel tub
· Surface on which tub will travel
Prediction
I predict that as the mass of the tub increases, the distance the tub can travel will decrease. This is because of friction. Friction is the force that resists the relative motion or tendency to such motion of two bodies in contact. Each time the mass of the tub is increased the pressure between the two contact points (the bottom of the tub and the floor) increases and thus the friction force acting in the opposite direction of the forward forcer of the tub overbalances it. This causes the tub to slow down and stop at a shorter distance each time its mass is increased, because the......
