Zsofi's Physics Midterm
Across
- 5. change in velocity over time
- 7. a force that works against an object in motion
- 8. a quantity that specifies magnitude and direction
- 11. the type of mechanical energy determined by the height/ position of an object
- 12. the amount of "stuff" something is made of
- 14. the property which states that an object in motion resists change in motion
- 16. when a roller coaster ride is about to end, it has the same amount of energy as when it started (if none is lost through heat or sound)-- because of what law?
- 17. the force on an object due to gravity
- 18. a type of friction due to air resistance
- 19. distance over time in a specific direction
Down
- 1. when a system is not traveling at a constant speed or at rest it's equation is?
- 2. when fnet=0 the forces are...
- 3. a quantity that only specifies magnitude
- 4. the sum of two or more vectors
- 6. the type of force created by a string or cable
- 7. when something falling is only under the influence of gravity (no drag)
- 9. the upward force which supports an object which is also always perpendicular to that object
- 10. the type of mechanical energy caused by an object being in motion
- 11. the rate at which you do work over time
- 13. (kg x m^2)/s^2
- 15. the amount of energy transferred to an object
