Warm-up Get your green folder On a notebook sheet of paper write “Kinetic and Potential Energy Notes” Make sure to put the date at the top corner Write your own definition of both kinetic and potential energy

6.8A Potential and Kinetic Energy The student is expected to compare and contrast potential and kinetic energy

Potential and Kinetic Energy

How is all energy divided? Potential Energy Kinetic Energy All Energy Gravitation Potential Energy Elastic Potential Energy Chemical Potential Energy

What is Potential Energy? oEnergy that is stored and waiting to be used later

What is Gravitational Potential Energy? oPotential energy due to an object’s position oP.E. = mass x height x gravity height x gravity Don’t look down, Rover! Good boy!

What is Elastic Potential Energy? oPotential energy due compression or expansion of an elastic object. Notice the ball compressing and expanding

What is Chemical Potential Energy? oPotential energy stored within the chemical bonds of an object

What is Kinetic Energy? oEnergy an object has due to its motion oK.E. =.5(mass x speed 2 )
