NOTES: Kinetic and Potential Energy

The ability to do work or cause change

The amount of matter in an object

The speed at which an object moves

The color of an object

Energy can change from potential to kinetic and vice versa, but it is never created or destroyed.

Potential energy can only be converted into kinetic energy, not the other way around.

Kinetic energy is always greater than potential energy in any system.

Energy can be created when potential energy is converted to kinetic energy.

Potential energy is the energy of motion.

Kinetic energy is stored energy.

Potential energy can transform into kinetic energy.

Kinetic energy can transform into potential energy.

Kinetic energy increases

Kinetic energy decreases

Kinetic energy stays the same

Kinetic energy disappears

As the coaster goes down, potential energy is converted to kinetic energy.

At the lowest point, the coaster has maximum kinetic energy and minimum potential energy.

As the coaster goes up, kinetic energy is converted to potential energy.

The sum of kinetic and potential energy is always changing.
