Across
- 3. The maximum speed an object will reach when falling through a substance
- 4. Tendency of an object to resist any change in it’s motion
- 5. The speed and direction of a moving object
- 6. The fall of an object on which only the force of gravity is acting
- 10. Distance and direction of an object's change in position from the starting point
- 12. Rate of change of velocity
- 13. If no external force acts upon a group of objects their total momentum does not change
- 14. Attractive force between two objects that depends on the masses of the objects and the distance between them
- 15. Every action made upon one object has an equal and opposite reaction back by that object
- 17. A push or pull exerted on an object
- 20. Acceleration of an object towards the center of a curved or circular path
Down
- 1. The acceleration of an object is in the same direction as the net force on the object, acceleration equals net force divided by its mass
- 2. An object moving at a constant velocity keeps moving at that velocity unless an unbalanced force acts upon it
- 7. The force that opposes the motion of objects that move through the air
- 8. Force that opposes the sliding motion between two touching surfaces
- 9. Distance and object travels per unit of time
- 11. A change in an object’s position relative to a reference point
- 16. Force that is directed towards the center of a curved or circular path
- 18. The length an object travels measured in SI units of meters
- 19. Gravitational force exerted on an object
