What is Energy?
• Energy is the ability to do Work or cause a change–Measured in Joules, like Work
![Page 3: The Nature of Energy](https://reader034.vdocuments.net/reader034/viewer/2022051418/56814f92550346895dbd4ea7/html5/thumbnails/3.jpg)
Kinetic Energy
• Kinetic Energy is the energy of motion
• All moving objects have Kinetic Energy (KE )
• What determines an object’s KE?– Mass & Velocity
determine the KE of an object.

Potential Energy
• Potential Energy (PE ) is stored energy– It has the potential or
“possibility” to do work
• Gravitational PE is energy that depends on height
• Elastic PE is for objects that can be stretched.

Mechanical Energy• Energy associated with
motion (KE & PE)
