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