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

• the force sent the person forward, there is an equal force pushing back on the skateboard
• the pull of gravity on the person is the same as on the skateboard, regardless of size
• the air resistane on the person is great and the friction on the skateboard is small
• the mass of the skateboard is the same as the mass of the person jumping off
