Energy Unit

Power

• The ability to influence others.

• The rate at which one form of energy is transformed into another.

• The total energy consumed over time.

• The maximum energy output of a system.

Motion

• Objects remain stationary in relation to one another.

• Objects change in position relative to another object.

• Objects move in a straight line only.

• Objects can only change speed, not position.

Force

• A push or a pull upon an object.

• A type of energy that can be converted into work.

• The mass of an object multiplied by its velocity.

• A measure of the distance an object travels.

Watt

• The SI unit of measurement for power which is the rate at which 1 joule/second (J/s).

• The SI unit of measurement for energy which is the rate at which 1 joule/second (J/s).

• The SI unit of measurement for voltage which is the rate at which 1 joule/second (J/s).

• The SI unit of measurement for current which is the rate at which 1 coulomb/second (C/s).

Chemical Energy

• The energy released during a chemical reaction.

• The energy contained in the chemical bonds between atoms.

• The energy required to break chemical bonds.

• The energy associated with the motion of molecules.

Energy

• The ability to create matter.

• The capacity to do work or cause change.

• A measure of temperature.

• A type of force.

Law of Conservation of Energy

• Energy can be created and destroyed.

• Energy can only be created.

• Energy cannot be created nor destroyed only converted from one form to another.

• Energy can be destroyed but not created.

Nuclear Energy

• The energy stored in the nucleus of an atom.

• The energy released during chemical reactions.

• The energy produced by solar panels.

• The energy generated by wind turbines.

Newton

• 1 meter/second² (m/s²)

• 1 kilogram meter/second² (kg·m/s²)

• 1 joule/second (J/s)

• 1 pound-force (lbf)

Electrical Energy

• The energy of electric charges.

• The energy produced by moving water.

• The energy stored in chemical bonds.

• The energy released during nuclear reactions.
