Unit 7 Energy

 Energy is the ability to do work or cause change. I can work…but I won’t

Work  Is done when a force moves an object through a distance. Not Work! Work!

Potential Energy  Is stored energy.  The potential energy of an object depends on its mass and position.  The larger an object is, the greater its potential energy.  The higher an object is, the greater its potential energy.

Kinetic Energy  Is energy in motion.  The kinetic energy of an object depends on its mass and its speed.  KE also depends on the amount of stored energy (PE) the object has.

The more PE an object HAS, the more KE the object WILL have!
