If the gymnast decreases the force they exerts on the trampoline, what will the reaction be?

• The gymnast will be pushed back by the trampoline with more force and go higher into the air

• The gymnast will be pushed back by the trampoline with less force and not go as high into the air

• No change will happen to the gymnast

According to Newton's Third Law, if someone jumps off a skateboard, the skateboard will roll backwards because-

• the mass of the skateboard is the same as the mass of the person jumping off

• the pull of gravity on the person is the same as on the skateboard, regardless of size

• the air resistance on the person is great and the friction on the skateboard is small

• for the force that sent the person forward, there is an equal force pushing back on the skateboard
