Across
- 3. strength or energy as an attribute of physical action or movement
- 4. metric unit
- 7. if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force
- 8. increase in the rate or speed of something
- 11. Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass
- 12. the speed of something in a given direction a course along which someone or something moves
- 13. every action in nature there is an equal and opposite reaction
Down
- 1. the rate at which someone or something is able to move or operate
- 2. equal in size and opposite in direction
- 3. the resistance that one surface or object encounters when moving over another
- 5. a unit of force
- 6. unequal in size and same direction
- 9. a tendency to do nothing or to remain unchanged not changed
- 10. property of a physical body and a measure of its resistance to acceleration when a net force is applied
