 Law of Conservation of Energy : a principle that states that energy is neither created nor destroyed, it simply changes form  Kinetic Energy : the energy of motion  Potential Energy : The energy stored in an object or substance.  Gravitational Potential Energy : the potential energy that exists between two objects that exert a gravitational pull on each other

 Energy can be categorized into two general types of energy. › Potential energy is energy that is not being used, so is often referred to as stored energy. › Kinetic energy is the energy of matter in motion

Batteries store energy! This car uses a lot of energy We get our energy from FOOD! Even this sleeping puppy is using stored energy.

 Energy in Action Energy in Action Remember ENERGY is never CREATED or DESTROYED…it can only be STORED or TRANSFERRED!!

 If I want to drop an apple from the top of one of these three things, where will be the most potential energy? A B C

 The higher the object, the more potential energy! A

 When stored energy begins to move, the object now transfers from potential energy into kinetic energy.

The semi- truck has more mass; therefore, more kinetic energy!

A. At the top of the fall. B. In the middle of the fall. C. At the bottom of the fall.

 C. At the bottom of the fall.  It has the most kinetic energy when its movement and speed are greatest, which is at the bottom of the fall right before it hits the ground.  When an object has the LEAST potential energy is when it has the MOST kinetic energy. BrainPop

 The Law of Conservation of Energy states that “energy can neither be created nor destroyed. It is simply converted from one form to another.” Newton’s Cradle. The kinetic energy of the ball on the left is transferred to the next ball, which transfers the energy to the next ball, so on down the line. When the last ball is hit, the kinetic energy causes it to kick out from the others. It swings back with kinetic energy, which it thus returns to the next ball and the progression continues.
