## unit 4: Work, Power, Energy

In this unit we will consider work, power, energy, and energy conservation. New topics will include conservative vs. non-conservative forces as well as complex energy conservation problems. We will also examine force vs. displacement graphs and use them to calculate work.

## standards

U4.1 - I can identify work as a force applied over a distance and calculate work.

U4.2 - I can apply the work-energy theorem to identify that the work done on a system produces a change in kinetic energy.

U4.3 - I can calculate the force exerted and potential energy of an ideal spring.

U4.4 - I can calculate the potential energy of objects in a uniform gravitational field.

U4.5 - I can identify energy storage mechanisms and energy transfers within a system.

U4.6 - I can apply conservation of energy in systems under the influence of spring or systems of 2 or more objects.

U4.7 - I can apply the definition of power and use it to calculate power supplied.

U4.2 - I can apply the work-energy theorem to identify that the work done on a system produces a change in kinetic energy.

U4.3 - I can calculate the force exerted and potential energy of an ideal spring.

U4.4 - I can calculate the potential energy of objects in a uniform gravitational field.

U4.5 - I can identify energy storage mechanisms and energy transfers within a system.

U4.6 - I can apply conservation of energy in systems under the influence of spring or systems of 2 or more objects.

U4.7 - I can apply the definition of power and use it to calculate power supplied.

**Due to time, we will only be testing on standards U4.2 and U4.6.**## reading
