Forms of energy

Front

What is sound energy?

Back

Sound energy is the energy associated with vibrations that travel through air, water, or solids, allowing us to hear sounds.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in an object.

Front

What is mechanical energy?

Back

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

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It powers our homes and devices.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as a ball held at a height.

Front

What is nuclear energy?

Back

Nuclear energy is the energy stored in the nucleus of an atom. It can be released during nuclear reactions.

Front

What is an example of a device that produces both sound and light energy?

Back

A television produces both sound and light energy.

Front

What is an example of a device that only produces sound energy?

Back

A trumpet is a device that primarily produces sound energy.

Front

How is electrical energy transformed into thermal energy?

Back

When electrical energy flows through a resistor, it can be converted into thermal energy, producing heat.

Front

What is the relationship between mechanical energy and work?

Back

Mechanical energy is used to perform work, which is the transfer of energy that occurs when a force is applied to an object.
