According to Newton’s Third Law, if someone jumps off a skateboard, the skateboard will roll backward 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.
