Newton's Laws and Forces
Across
- 3. A pulling force that works across space.
- 6. A force that one surface or object encounters when moving over another; it is a resistance to motion.
- 7. A change in position over time.
- 8. The distance an object travels per unit of time.
- 9. The relationship between speed and direction of a moving object.
- 10. The result of a force.
- 11. 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.
- 14. The combined forces acting on an object.
- 15. The force or speed with which something moves; the more mass, the more momentum.
- 17. For every action there is an equal and opposite reaction.
- 19. 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.
- 20. The tendency of an object to resist a change in motion.
Down
- 1. 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.
- 2. English mathematician and scientist who defined the laws of motion and gravity. Tried to explain motion of the universe.
- 4. A push or pull exerted on an object.
- 5. The acceleration of an object depends on the mass of the object and the amount of force applied.
- 12. Force = mass x acceleration
- 13. 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.
- 16. The rate at which velocity (speed and direction) changes (speed up or slow down).
- 18. A measure of the amount of matter in an object.
