Newton's Law of Motion

2. - A measurement of how fast an object moves relative to a reference point.
4. - The tendency of a body to resist a change in motion or rest.
5. - How far one thing is from another thing.
6. - An invisible force that pulls objects toward each other.
10. - To move or cause to move at decreasing speed.
14. - The rate of change of velocity, or how fast an object or person speeds up.
15. - Refusal to comply with or accept something.
18. - The ability to maintain a controlled body position during task performance.
20. - The measure of the force of gravity on an object.

1. - The energy an object has due to its motion.
3. - When one force is greater than another, the forces are not balanced.
7. - The amount of force required to make a mass of 1kg accelerate (move) at a rate of 1 metre per second squared.
8. - The combination of all the forces acting on an object simultaneously.
9. - A force, the resistance of motion when one object rubs against another.
11. - To draw or haul toward oneself or itself, in a particular direction, or into a particular position.
12. - A direction is the line or course along which something moves, lies, or points.
13. - Change with time of the position or orientation of a body.
16. - The amount of matter an object contains.
17. - The speed in a particular direction.
19. - To press against with force in order to drive or impel.
