How can we explain the motion of objects?

All things move based on how much mass they have and it’s relevance to gravity/distance from the ground. As objects moved, force is moving them. An example would be a wagon on a hill. If the wagon is on wheels at the top of the hill and someone uses force to make the wheels move, the wagon will roll down the hill due to inertia and other elements.

Yes i think so not 100 percent sure though

Okay this will take 1 hour okay dont forget me.
