Across
- 3. The force of attraction between all matter.
- 8. The force that a surface) pushes back up with. It is always perpendicular to the surface the object is on.
- 9. Newton described this as the amount of matter. It is the inertia of an object.
- 10. Rate of change of velocity.
- 12. A form of motion experienced by an object that is thrown and moves along a curved path under the action of gravity only
- 13. How far you go. Sometimes the height or length.
- 14. This opposes (goes against) motion.
- 17. The curve followed by a projectile.
- 18. This equals the change in momentum. It is calculated by Force x time.
- 20. How hard it is to stop something.
- 21. Reluctance to change.
Down
- 1. Distance in a particular direction.
- 2. One of these will give a mass of 1kg an acceleration of 1 ms-2
- 4. The overall force when more than one force is combined.
- 5. The horizontal and vertical parts we get when we resolve a vector.
- 6. Speed in a given direction.
- 7. The constant velocity when the forces acting on a moving object balance.
- 11. When the net force in any particular direction equals zero.
- 15. Split a vector into vertical and horizontal parts.
- 16. The gravitational force on a body it can vary throughout the Universe
- 19. Equal and opposite to an action on a different object.
