Principle of Conservation of Charge

The net charge an isolated system remains constant during any physical process.

Power

The rate at which work is done.

Potential Difference

The work done per unit positive charge.

Resistance

The ratio of the potential difference across a resistor to the current in the resistor.

Current

The rate of flow of charge.

Displacement

The change in position of an object.

Speed

The total distance travelled per total time.

Velocity

The rate of change of position.

Acceleration

The rate of change of velocity.

The Principle of Conservation of Mechanical Energy

The total mechanical energy in an isolated system remains constant.

Kinetic Energy

Energy an object possesses because of its motion.

The Law of Conservation of Energy

The total energy of an isolated system remains constant

Ohm’s Law

The current in a conductor is directly proportional to the potential difference across it, provided its temperature remains constant.
