KE, PE, & Conservation of Energy
By Cristina Sanchez
Kinetic Energy & Potential Energy
Kinetic energy is energy IN MOTION. (Doing work)
Ex: Legs pumping bicycle pedals
Formula: KE= ½ mv²
Potential Energy
Potential energy is energy IS STORED. (Not doing work)
Ex: Any object NOT in motion.
Formula: PE=mgh
Conservation of Energy
Conservation of energy means energy is NEITHER created OR destroyed but ONLY changes forms.
Ex: When kicking a ball that is not in motion energy is transferred from the kicker's body to the ball, energy was not created nor destroyed, just transferred.
Kinetic Energy
Roller coaster in motion
Potential Enery
Energy sitting still
Conservation of Energy
Energy changing forms (not created, not destroyed)
