Unit 1: Energy Electromagnetic Spectrum WS #1
Background: Energy is the ability to do work.
Work: the application of a force over a distance
Example: Work is done when energy is transferred to an object
Work-Energy Principle -The change in the kinetic energy of an object is equal to
the net work done on the object. For example: Mechanical work is when an object
is at rest and it is forces to move. The energy of a moving object is called kinetic
energy.
