The "reaction" force does not cancel the "action" force because:
Correct answer: B. they are on different bodies
- A. the action force is greater than the reaction force
- B. they are on different bodies
- C. they are in the same direction
- D. the reaction force exists only after the action force is removed
Explanation
For every action there is a reaction. This action and reaction are equal magnitude but opposite in direction. Action and reaction never act on the same body; they act on the different bodies.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
