Types of Energy

Front

What is energy transformation?

Back

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

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, which can be harnessed from the sun and converted into electrical energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object, representing the energy of motion and position.

Front

What is gravitational energy?

Back

Gravitational energy is the potential energy held by an object because of its height above the ground, which can be converted to kinetic energy when it falls.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as 1/2 mv², where m is mass and v is velocity.

Front

What is the difference between potential and kinetic energy?

Back

Potential energy is stored energy based on an object's position, while kinetic energy is the energy of an object in motion.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons, often used to power devices and appliances.

Front

What is an example of energy transformation in a solar power plant?

Back

A solar power plant transforms radiant energy from the sun into electrical energy.

Front

Which of the following is not a type of energy: Mechanical, Gravitational, Electrical, or A wave?

Back

A wave is not a type of energy; it is a disturbance that transfers energy.

Front

What is an example of mechanical energy?

Back

A moving car has mechanical energy due to its motion (kinetic) and its position (potential) relative to the ground.
