- 4. The potential energy of an object depends upon the ___________ above the earth's surface.
- 7. After lifting a book up 1.5 meters vertically, what type of energy have you given it?
- 12. This is the measurement of how much work an object can do.
- 13. This is measured in kilograms and it states the amount of "stuff" you are made of.
- 15. This means to change your velocity, and there are three ways to do that. You can either speed up, slow down, or change your direction.
- 16. This is the type of potential energy stored within something that stretches, like a rubber band.
- 18. Work is done on an object only when a force is applied, and this is changed due to the external force.
- 19. In order to do work, the force you apply to an object has to be in the same ___________ as the movement of the object.
- 21. This is the measurement of energy within food. 1 unit of this food energy is equal to 4200 Joules.
- 24. This can help us determine how much energy is stored within a stretched or compressed spring.
- 25. The units of energy.
- 27. Anytime something is moving, we say that it has this special type of energy.
- 28. This is the unit in which power is measured.
- 29. This states that the total initial energy of a system has to be the same as the final energy of a system.

- 1. An object can have multiple forces acting on it, yet it won't accelerate. Newton's 2nd Law of Motion states that you can only cause something to accelerate by applying ________ _________.
- 2. Work is calculated by multiplying the distance an object has moved by the __________ _________ that was applied to that object.
- 3. This is the measurement of how much force you exert on the earth and is measured in Newtons.
- 5. Once you are moving, this is your body's tendency to maintain the motion that it currently has. If you are moving in a straight line, the only way to get you to turn is by applying an outside force.
- 6. If you square this value, then multiply it by 0.5 and the mass, you can determine how much energy an object has while it is in motion.
- 8. The amount of mass will never change. We will never make more, and we can never get rid of any of it.
- 9. When you want to determine the total force acting on an object, this is the vector sum of all the forces.
- 10. This is a force that does work, for example, when a basketball is pulled down back to earth.
- 11. This is a type of force that does work against an object with it moves. It opposes motion.
- 14. This is the rate in which work gets done. Take the amount of work done, and divide it by the time it took.
- 17. In physics, this word refers to how far you have moved an object after applying a force to it.
- 20. This is the total measurement of energy within a system and it will never change, even though energy might be transforming between kinetic to potential, this amount of energy will never change.
- 22. This word means that something has the ability to become or develop into something else in the future.
- 23. Watts researched how fast a horse could do work. He found that 756 Joules is equal to one _________.
- 26. If you want to determine the amount of work you have done, then you have to multiply the force applied by the __________ that the object moved.
- 30. Your weight is measured in units of __________. This is different than mass, which is measured in kilograms.
