What causes an object to move then suddenly stop?
Newton says that a body in motion will stay in motion until an outside force acts upon it. In this and most other real world cases, this outside force is friction. The friction between your ice skates and the ice is what causes you to slow down and eventually stop.
Do objects ever stop moving?
Gravity is a force (therefore requiring an action), and according to Newton’s 3rd law the object is required to supply a counter-force. So, theoretically (for me, at least) when any object is dropped, it is always changing directions, and therefore always moving (no matter how small).
Can gravity make an object stop moving?
Because, gravity not only holds us in her grip
