Question

What does PE + KE = __

Answer 1

Answer:

Energy that is dependant on height is called gravitational potential energy.

The formula for potential energy is:

                    G.P.E.=mgh

Weight (mass x gravity) determines the amount of potential energy.

Is there potential energy in the 5 forms of energy?

Yes, potential energy can be found in fossil fuels, within the foods you eat, and the batteries that you use.  

Conservation of Energy:

It is important to understand that each form of energy does not exist separately but undergoes change from one to another without a net loss in energy.  Consider this example:

As a projectile is launched into the air KE is at its maximum.  As the projectile gains altitude PE becomes greater than KE.  At the top of its arc, PE is at its maximum.  The whole cycle reverses itself on the way down.

As you can see, the loss in KE is a gain in PE.  Energy is not lost but conserved.

Law of conservation of energy.

   Energy cannot be created nor destroyed.  It can be transformed from one form to another, but the total amount of energy never changes.

Answer 2

Hello,

Let’s start off by saying potential energy stores a objects energy, and kinetic energy is a object in motion. You can use the mass of an object to find kinetic energy. As far as I know potential energy and kinetic energy combined is something that’s not moving but when it falls for example it can create kinetic energy. Hope this helps!
