Unit 1 Forms of Energy Review

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 internal energy of an object due to the kinetic energy of its molecules. It is often associated with heat.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves. It is a form of mechanical energy that travels through a medium such as air, water, or solids.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It is commonly used to power devices and appliances.

Front

What is electromagnetic energy?

Back

Electromagnetic energy is a form of energy that travels through space as waves, including visible light, radio waves, and X-rays.

Front

Can energy be created or destroyed?

Back

No, according to the law of conservation of energy, energy cannot be created or destroyed; it can only be transformed from one form to another.

Front

What is an example of energy transformation from chemical to mechanical?

Back

Eating lunch and then going to play is an example of transforming chemical energy from food into mechanical energy used for movement.

Front

What type of energy is used when riding a bicycle?

Back

Mechanical energy is used when riding a bicycle, as it involves the movement of the cyclist and the bicycle.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a rock at the top of a hill has gravitational potential energy.
