Types of Energy - LVL 3

Front

What is kinetic energy?

Back

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

Front

Give an example of kinetic energy in everyday life.

Back

An example of kinetic energy is a moving car or a person running.

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 a substance.

Front

Provide an example of thermal energy.

Back

An example of thermal energy is the heat produced by a sauna or a steaming cup of coffee.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

Give an example of elastic potential energy.

Back

An example of elastic potential energy is a compressed spring or a stretched rubber band.

Front

What is the relationship between kinetic energy and motion?

Back

Kinetic energy is directly related to the motion of an object; the faster an object moves, the more kinetic energy it has.

Front

How does mass affect kinetic energy?

Back

The kinetic energy of an object increases with its mass; doubling the mass of an object will double its kinetic energy if the velocity remains constant.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

How can thermal energy be transferred?

Back

Thermal energy can be transferred through conduction, convection, and radiation.
