Unit 5 Review
How do you calculate kinetic energy?
When it is used. Energy changes from one form to another when it is used. Example: You plug in a vacuum, you turn it on, move it back and forth, while you are moving back and forth it sucks up the dirt. It went from electric to mechanical.
What is the Law of Conservation of Energy?
In a swing or a pendulum, the potential energy is greatest at the beginning and end of the swing. At what point in the swing or the pendulum is the potential energy equal to the kinetic energy?
What are the different types of machines?
How does an inclined plane make moving easier?

Machines and MA Page Simple machines ► Means a machine that only uses the forces directly applied and accomplishes its work with a simple motion.
UNIT 7 Energy & Work. Energy Energy – the ability to do work (the ability to cause a change)
Mechanical Advantage The measurement of how useful a machine is to the job.

Sci. 5 – 2 Energy Conversions Pages A. Energy Conversions- a change from one form of energy to another.
Work, Power, and Machines
Energy transfer from one form of energy into another _________________________________ Can be one form to one other form or one form to ___________________.
Law of Conservation of Energy Energy can neither be created nor destroyed It can change forms – Sound becomes mechanical in your ear – Chemical becomes.

What is mechanical advantage?
Machines Section 10.2 Physics. Objectives Demonstrate knowledge of why simple machines are useful. Communicate an understanding of mechanical advantage.
Work Done by a Varying Force (1D). Force Due to a Spring – Hooke’s Law.
