Almost everything the other person said was correct, but here are the answers I got:
1. a pull or push of any kind - FORCE
2. a change of position of an object - MOTION
3. any change in the speed or direction of an object's motion - ACCELERATION
4. an attractive force acting between two massive objects - GRAVITY
5. a force that resists motion between objects that are touching - FRICTION
I put the answers in all caps so it would be easier to read. Hope this helps!!
