A skateboard rolls down a hill, reaches the level surface and eventually comes to a stop. The fact that the skateboard ultimately stops is best explained by ____.

an unbalanced force would be required to keep the sled moving forward at constant speed

the presence of an unbalanced force (e.g., friction) can cause a moving object to stop

the presence of inertia causes it to stop

the natural tendency of any object is to ultimately stop
