Amplify Force and Motion

What is wrong with this collision model?

• The velocity of the objects should be in the same direction.

• The force arrows should be in the same direction and equal size.

• The force arrows should be the same size or equal strength.

• Nothing is wrong with this collision model.

When you apply a strong force in the opposite direction to the motion of an already slow moving object what is the most likely change in motion?

• Speed up in the same direction of its current motion.

• Stop moving for a second and then begin to move again in the opposite direction.

• The object will change directions and continue moving.

• The object will not be affected by a strong force, only a weak force will make a difference.
