ENERGY
BASICS
ENERGY is the ability to do work or cause a change in the direction, speed, shape or temperature of an object
POTENTIAL ENERGY is stored energy due to an objects position or condition
KINETIC ENERGY is the energy of motion
POTENTIAL ENERGY depends on the mass and the height of the object.
KINETIC ENERGY depends on the mass and the velocity (speed) of an object.
Energy is measured in units called JOULES.
LAWS OF ENERGY
1st - Energy cannot be created or destroyed
2nd - Energy transformations are never 100% efficient, meaning can be transferred from one place to another and converted from one form to another, but any time either of these occur some of the total energy must be lost as HEAT
HEAT or THERMAL ENERGY is energy lost to the motion of atoms or molecules, raising their temperature, often the result of FRICTION between two masses
