Blocks A and B in the model are made of the same material but are different sizes. They are both placed on a smooth, flat, slippery surface. The blocks are stable and unmoving when placed on the surface, but move easily when even a very small force is applied. If the forces shown are applied to each object, which will have the greater change in motion?

• Both

• Neither

• Block A

• Block B

If the force applied to Block A increased, how would this affect the change in motion?

• the change in motion will increase

• the change in motion will decrease

• it won't affect he change in motion

• Not enough information to tell.
