Forms of Energy

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 types of energy does a toy oven use to bake cakes?

Back

A toy oven uses electrical energy (from the lightbulb) and thermal energy (to bake the cakes).

Front

What type of energy is responsible for melting ice cream?

Back

Thermal energy (or heat) is responsible for melting ice cream.

Front

Define thermal energy.

Back

Thermal energy is the energy that comes from the temperature of matter; it is the total kinetic energy of particles in a substance.

Front

What is the difference between heat and thermal energy?

Back

Heat is the transfer of thermal energy from one object to another, while thermal energy is the total energy of all the particles in an object.

Front

What is sound energy?

Back

Sound energy is a form of energy that is associated with the vibration of matter, which creates sound waves.

Front

What is electrical energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or arrangement.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, dependent on its mass and velocity.

Front

What are the three main forms of energy?

Back

The three main forms of energy are mechanical energy, thermal energy, and electrical energy.
