If a body A exerts a force on body B (action), then body B exerts a
force on body A (reaction). These
forces have the same magnitude but opposite directions.
The two forces act on different bodies.
Consider a horse pulling a buggy. The force that the horse exerts on the
cart and the force that the cart exerts on the horse are equal and

A. true
B. false
Consider a horse pulling a buggy. The weight of the horse and the normal force

A. true
B. false
Consider a man jumping up from the ground while he is still in contact with the
