3. The rate at which an object's displacement changes over time.
5. A push or pull on an object that can change its motion.
9. The change in position of an object over time.
10. The energy possessed by an object due to its motion.
11. When the forces acting on an object are equal and opposite, resulting in no change in motion.
12. The force that opposes the motion of an object.
14. The rate at which an object's velocity changes over time.
16. The rate at which an object covers a distance.
17. The vector sum of all the forces acting on an object.
19. The force of attraction between objects with mass.
20. The rate at which an object slows down.

1. The tendency of an object to resist changes in its motion.
2. The force that opposes the motion of an object through the air.
4. An event in which two or more objects come into contact with each other and exchange energy.
6. The energy possessed by an object due to its position or condition.
7. When the forces acting on an object are not equal and opposite, resulting in a change in motion.
8. The amount of space between two points
13. The product of an object's mass and velocity.
15. The ability to do work or cause a change.
18. The amount of matter in an object.
