energy

3. Machine: A machine that does work with only one movement of the machine
6. Potential energy: energy stored within the nucleus of an atom. It is energy that keeps the subatomic particles of the atomic nucleus together.
7. transformation: the conversion of energy from one form to another.
8. Ratio of output work to input work
10. hour: equals the energy consumed by a 1,000 watt device that is operating for 1 hour.
12. transfer: The movement of energy
13. Potential energy: energy stored within the bonds between atoms of matter. It is used to keep atoms bonded together.
16. energy: energy that an object has due to its motion or position.
18. Dissipation: loss of energy

1. Machine: Combination of two or more simple machines
2. Energy (KE): energy of motion.
4. the rate at which energy is used (the amount of energy consumed per unit time).Watt: equal to 1 Joule per second.
5. Potential Energy (PEg): energy stored in an object as a result of its height.
9. Energy (PE): stored energy of position
11. applying a force to move or change something.
14. defined as the amount of energy exerted when a force of one newton is applied over a displacement of one meter.
15. of Conservation of Energy: energy cannot be created or destroyed but it can change to different forms
17. is the ability to do work.
