What is electrical energy?

Back

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

What is sound energy?

Back

Sound energy is a form of energy that is associated with the vibration of matter. It is produced when an object vibrates, creating waves that travel through a medium such as air.

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.

What is kinetic energy?

Back

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

What is potential energy?

Back

Potential energy is the stored energy of an object based on its position or state, such as gravitational potential energy, which depends on height.

What is the relationship between energy and work?

Back

Work is done when energy is transferred from one system to another. The amount of work done is equal to the energy transferred.
