Physics: Energy and Simple Machines

energy in our world?
7.1 — Energy provides the ability to do work and can exist in many forms.

7.1.a. Work is the process of making objects move through the application of force.
7.1.b. Energy can be stored in many forms and can be transformed into the energy of motion.

C12. Explain the relationship among, force, distance and work, and use the relationship (W = F x D) to calculate work done in lifting heavy objects.

C13. Explain how simple machines, such as inclined planes, pulleys and levers, are used to create mechanical advantage.

C14. Describe how different types of stored (potential) energy can be used to make objects move.
