Energy TEST review

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is greatest when the object is at its highest point.

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is a unit of speed?

Back

The unit of speed is meters per second (m/s).

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as electrical energy to thermal energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object that is used to do work.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons through a conductor.

Front

What is an example of energy transformation in a light bulb?

Back

In a light bulb, electrical energy is transformed into light energy and thermal energy.
