Kinetic Energy

What is Energy? Energy is the ability to do work. Work is done when a force causes something to move

Kinetic Energy is energy in motion Any type of matter that is in motion has kinetic energy

Kinetic Energy There are many forms of Kinetic Energy Some forms include: light (radiant), thermal (heat), sound (acoustic), electrical, and mechanical

Examples of Kinetic Energy A skier skiing down a hill. An arrow shot through the air. A roller coaster moving.

Kinetic Energy Equation The amount of kinetic energy depends on 2 variables Mass of the object (m) and The speed of the object (v)

Kinetic Energy Equation To identify the kinetic energy of a moving object, the following formula is used. KE = 0.5 x m x v2 m = mass of object v = speed of object
