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.
