I like playing basketball. So I'm the object in motion. Until an unbalanced force comes and hits me I fall and stay at rest.
If you are running, your feet always go down because of gravity, same with scootering, the scooter stays on the ground because of gravity, same with volleyball and any other sport. How you score in volleyball is when the ball hits the ground on the other team's side, when the ball finally falls to the ground, it is because of gravity
