Question

If two objects with different masses are pushing each other, which exerts the greater force?

Answer 1

Newton's 3rd law of motion says that for every action there is an equal and opposite reaction.

This means that the smaller mass exerts a force on the larger mass that is equal in magnitude and opposite in direction to the force that the larger mass exerts on the smaller mass.

Choice 2

Answer 2

Answer:

4. The object with the greater mass exerts the greater force on the smaller object because the larger object has more inertia.

Explanation:

Because the quarter has more mass, gravity exerts more force on it. But greater mass also means more inertia, so the greater force does not produce a larger acceleration. Objects with different masses fall with the same acceleration.
