Forms of Energy

Front

What is mechanical energy?

Back

Mechanical energy is the energy that an object has due to its motion (kinetic energy) or its position (potential energy).

Front

What is thermal energy?

Back

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

Front

What type of energy is used when riding a bicycle?

Back

Mechanical energy is used when riding a bicycle.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another object.

Front

How does rubbing hands together produce warmth?

Back

Rubbing hands together produces warmth by converting mechanical energy into thermal energy through friction.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, such as from air to water.

Front

What is absorption in terms of energy?

Back

Absorption is the process by which an object takes in energy, such as light or sound, rather than reflecting or transmitting it.

Front

What is an example of potential energy?

Back

An example of potential energy is a rock sitting at the top of a hill, which has the potential to roll down.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What is the relationship between energy and work?

Back

Work is done when energy is transferred from one object to another, resulting in a change in motion or position.
