14.1.1 Describe the conditions that must exist for a force to do work on an object.

14.1.2 Calculate the work done on an object.

14.1.3 Describe and calculate power.

14.1.4 Compare the units of watts and horsepower as they relate to power.

15.1.2 Relate kinetic energy to mass and speed and calculate these quantities.

15.1.3 Analyze how potential energy is related to an object’s position and give examples of gravitational and elastic potential energy.

15.1.4 Solve equations that relate an object’s gravitational potential energy to its mass and height.

15.1.5 Give examples of the major forms of energy and explain how each is produced.

15.2.1 Describe conversions of energy from one form to another.

15.2.2 State and apply the law of conservation of energy.

15.2.3 Analyze how energy is conserved in conversions between kinetic energy and potential energy and solve equations that equate initial energy to final energy.

15.2.4 Describe the relationship between energy and mass and calculate how much energy is equivalent to a given mass.

## State Standards Addressed by this unit

### CP.1.15

Understand and explain that whenever the amount of energy in one place or form diminishes, the amount in other places or forms increases by the same amount.
CP.1.19 Understand and explain that the energy released whenever heavy nuclei split or light nuclei combine is roughly a million times greater than the energy absorbed or released in a chemical reaction. (E=mc2)
CP.1.20 Realize and explain that the energy in a system is the sum of both potential energy and kinetic energy.
CP.2.7 Describe that among the surprising ideas of Albert Einstein's special relativity is that nothing can travel faster than the speed of light, which is the same for all observers no matter how they or the light source happen to be moving.
CP.2.8 Explain that the special theory of relativity is best known for stating that any form of energy has mass, and that matter itself is a form of energy. (E=mc2)
CP.2.9 Describe that general relativity theory pictures Newton's gravitational force as a distortion of space and time.
CP.2.12 Describe that later, Austrian and German scientists showed that when uranium is struck by neutrons, it splits into two nearly equal parts plus one or two extra neutrons. Note that Lise Meitner, an Austrian physicist, was the first to point out that if these fragments added up to less mass than the original uranium nucleus, then Einstein's special relativity theory predicted that a large amount of energy would be released. Also note that Enrico Fermi, an Italian working with colleagues in the United States, showed that the extra neutrons trigger more fissions and so create a sustained chain reaction in which a prodigious amount of energy is given off.
