Forms of Energy

Front

What is light energy?

Back

Light energy is a form of energy that is visible to the human eye and is produced by the vibration of electrically charged particles.

Front

What is mechanical energy?

Back

Mechanical energy is the energy associated with the motion and position of an object. It can be kinetic (energy of motion) or potential (stored energy due to position).

Front

What is thermal energy?

Back

Thermal energy, also known as heat energy, is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in a substance.

Front

What type of energy does a battery produce?

Back

A battery produces electrical energy, which is the energy of moving electrons.

Front

What are the two forms of energy used when playing cymbals?

Back

Playing cymbals uses mechanical energy (from the motion of striking) and sound energy (the sound produced by the vibration of the cymbals).

Front

What is sound energy?

Back

Sound energy is a form of energy that is produced when an object vibrates, creating waves of pressure that travel through a medium such as air, water, or solids.

Front

What is the relationship between energy and work?

Back

Energy is the capacity to do work. When work is done on an object, energy is transferred to that object.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a rock at the top of a hill has gravitational potential energy.

Front

What is kinetic energy?

Back

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

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.
