Energy Transfer: The movement of energy from one object to another.

Two examples of kinetic energy transfer: A moving billiard ball striking another billiard ball, a person throwing a baseball.

Kinetic energy transfers between objects when one object pushes or applies a force to another object, causing it to move.

In a hydroelectric dam, kinetic energy is highest in the flowing water before it reaches the turbine, and potential energy is highest in the water held in the reservoir at a higher elevation.

Mechanical energy: The sum of potential and kinetic energy in a system.

Thermal energy: The energy associated with the heat of an object or system.

Potential energy formula: PE = mgh (mass x gravity x height)

Kinetic energy formula: KE = 0.5mv^2 (0.5 x mass x velocity^2)

Two types of conservative forces: Gravity and elastic forces.

Two types of non-conservative forces: Friction and air resistance.

Calculating kinetic energy: KE = 0.5 * 0.5 kg * (2.0 m/s)^2 = 0.5 J

Calculating potential energy: PE = 0.5 kg * 9.8 m/s^2 * 1 m = 4.9 J
