Forms of Energy

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It is released or absorbed during a chemical reaction.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.

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 the particles in an object.

Front

How is chemical energy related to food?

Back

Chemical energy in food is stored in the bonds of molecules and is released when the body metabolizes the food for energy.

Front

What is an example of mechanical energy in everyday life?

Back

An example of mechanical energy is a moving car, where the energy is due to its motion (kinetic) and its position (potential).

Front

What happens to mechanical energy when a jack in the box is activated?

Back

When a jack in the box is activated, mechanical energy is stored in the compressed spring and is released to make the jack jump out.

Front

What is the relationship between thermal energy and temperature?

Back

Thermal energy is directly related to temperature; as the temperature of an object increases, its thermal energy also increases.

Front

Can chemical energy be converted to other forms of energy?

Back

Yes, chemical energy can be converted to other forms of energy, such as thermal energy during combustion.

Front

What is an example of thermal energy transfer?

Back

An example of thermal energy transfer is when you place your hands near a fire and feel the heat radiating towards you.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, which can be converted to kinetic energy.
