Across
- 1. the sum of all the forces acting on a mass
- 4. when one object hits another object
- 6. to pull toward each other
- 7. a unit of mass
- 9. a force acting between surfaces in contact. This force acts to resist motion.
- 12. the distance traveled by an object in a unit of time
- 13. an interaction between objects. A push or pull.
- 16. energy of motion
- 17. a force of attraction between masses
- 18. how far between two objects or locations
- 21. toward it
- 22. a standard for evaluating or testing something
- 23. force applied over a period of time
- 24. energy stored in the position or condition of an object
- 26. a measure of the quantity of matter in an object
- 28. a unit that describes measurement of force
- 29. the location of an object
Down
- 2. a section of a vehicle designed to absorb energy during a collision and protect passengers
- 3. the maximum speed an object can obtain during free fall through air
- 5. total distance divided by total time.
- 6. the force exerted by air molecules on objects moving through air
- 8. the change of velocity per unit of time
- 10. speed that does not vary over time
- 11. any factor that can be changed
- 14. a restriction or limitation
- 15. a measurement of the force of gravity from a massive object (such as Earth) pulling another
- 19. a unit of energy
- 20. a symbol that indicates change in a quantity
- 25. usable power that can be transferred or converted to different forms, but cannot be created or
- 27. in math or physics, the steepness of a line on a graph
