Push to move WHY DO WE NEED TO PUSH THINGS
TO GET THEM TO MOVE?


Things don't start moving by themselves. If something is at rest, you have to push it to get it going. For a push of a given size, some objects will move more easily than others. Inertia is a measure of how much something resists being put into motion. Mass is a measure of inertia. The more massive an object is, the harder you have to push to get it moving.
