Newton's Laws

1. Force = mass x acceleration
4. Newton's Law of motion that explains: If one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object.
5. The result of a force.
9. The tendency of an object to resist a change in motion.
12. A force that one surface or object encounters when moving over another; it is a resistance to motion.
13. Forces that are physically touching and cause change.
14. A pulling force that works across space.
17. The combined forces acting on an object.
18. Newton's Law of motion that explains: The acceleration of an object depends on the mass of the object and the amount of force applied.
19. The distance an object travels per unit of time.
20. Forces that are not physically touching and cause change across space.

2. The rate at which velocity (speed and direction) changes (speed up or slow down).
3. The relationship between speed and direction of a moving object.
6. Forces acting on an object that combine and form a net force that is not zero; object will change direction, speed up or slow down, stop, start moving.
7. English mathematician and scientist who defined the laws of motion and gravity. Tried to explain motion of the universe.
8. forces that describe: every action there is an equal and opposite reaction.
10. Newton's Law of motion that explains: An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
11. A change in position over time.
12. A push or pull exerted on an object.
15. Forces acting on an object that combine and form a net force of zero; object will stay still or move at the same speed and going in the same direction.
16. A measure of the amount of matter in an object.
