Kinetic Energy Presented to Physical Science Fall 2009 By K. Whitfield
How to Calculate Kinetic Energy (KE) • Factors that affect KE • Mass-more mass, more KE • Velocity-more velocity, more KE
Putting the Factors Together • Equation: • KE=1/2mv2
Sample Problems • How much KE does a 2.0 kg baseball moving 10 m/s have? • How much work can it do? • What is the average KE of the marble in your roller coaster?
