Across
- 3. a unit of weight in the US
- 4. the law of acceleration, acceleration happens when a force acts on an object
- 6. an object at rest will stay at rest unless acted upon by an unbalanced force, an object in motion will stay in motion unless acted upon by an unbalanced force
- 9. when the speed of an object remains the same
- 10. the sum of forces acting on a particular object
- 12. push or pull on an object
- 14. two forces are the same strength but in opposite directions
- 17. a state in which opposing force or influences are balanced
- 18. when the force applied to an object is stronger in one direction
- 19. free fall, falling down due to gravity
- 23. a place where something is located
- 25. the resistance of one surface against another
- 27. the state of being stretched tight
- 28. a part that is added to something
- 29. momentum is neither created nor destroyed, but changed due to force
- 30. a surface that has one higher end than the other
Down
- 1. the speed of an object at a particular moment in time
- 2. the act of compressing
- 5. opposing the movement between two surfaces against each other
- 7. the rate at which something is moving
- 8. the average rate at which something is moving
- 11. downward movement under the force of gravity
- 13. for every action, there is an equal and opposite reaction
- 15. the speed of something in a specific direction
- 16. the force of friction on an object that isn't moving
- 20. a quantity having direction as well as magnitude
- 21. an increase in the rate of speed
- 22. the quantity of motion of a moving object, measured as a product of its mass and velocity
- 24. the SI unit of force
- 26. the resistance to motion/force
