Conservation of Energy

The Law of Conservation of Energy Energy cannot be CREATED or DESTROYED. Energy is just CONVERTED from one form to another.

The amount of energy present at the beginning of a process EQUALS the amount of energy present at the end of the process.

PE + KE (before) = PE + KE (after)

Potential Energy Energy ______________ to be released

Elastic Potential Energy Elastic PE depends on the ________________ in the object

Gravitational PE depends on: MASS of the object HEIGHT of the object Acceleration due to GRAVITY

PE = mgh

Kinetic Energy Energy contained within ________________ objects.

Kinetic Energy depends on: MASS of an object VELOCITY of the object

KE = ½ mv 2

When you are at the top of the roller coaster, you are high off the ground and you have a lot of _______energy.

As the roller coaster moves down the hill the potential energy is _____________ into Kinetic energy. (The car loses _______ but gains _____)

As the roller coaster travels up the next hill _______energy (speed) is converted back to ________energy (height).

Where is the PE the greatest?

Fly Wheel

KE=0 PE=90J

KE=0 PE=90J KE= PE=60J

KE=0 PE=90J KE=30J PE=60J

KE=0 PE=90J KE=30J PE=60J KE= PE= 30J

KE=0 PE=90J KE=30J PE=60J KE=60J PE= 30J

KE=0 PE=90J KE=30J PE=60J KE = PE = 0J KE=60J PE= 30J

KE=0 PE=90J KE=30J PE=60J KE =90J PE = 0J KE=60J PE= 30J
