Energy

Energy means

The ability to do work

What is energy measured in?

Joules/J

Mechanical Energy/ ME means

Kinetic and Potential energy combined

Potential Energy/PE

Energy stored due to an object's position

Kinetic Energy/KE

Energy of motion by moving objects

Law of Conservation of Energy is

Energy cannot be created or destroyed

Work

transfer of energy

A result of work

An object has changed KE, PE, Thermal E, and all of the above

Distance must be in the same direction as the force

Distance must be in the same direction as the force

The amount of work done on an object depends on...

How much energy is applied, and how far the force causes the object to move in the same direction

No Movement

No work

Power is

The rate at which work is done, or the rate of energy transfer

What is power measured in

watts

Power and Work have a direct relationship. Why?

The more work that needs to be done, the more power you need.

Power and time have an indirect relationship. Why?

The less time you need, the more you have to apply.
