Energy Transformations

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting chemical energy in food into mechanical energy for movement.

Front

What type of energy is associated with the motion of an object?

Back

Mechanical energy is the energy associated with the motion of an object.

Front

What type of energy is stored in food?

Back

Chemical energy is stored in food and is released when the food is consumed and metabolized.

Front

What is the primary source of thermal energy on Earth?

Back

The sun is the primary source of thermal energy on Earth.

Front

Can energy be created or destroyed?

Back

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

Front

What type of energy is released during a chemical reaction?

Back

Chemical energy is released during a chemical reaction.

Front

What is an example of potential energy?

Back

A drawn bow has potential energy because it is capable of doing work when released.

Front

What type of energy do muscles use to perform work?

Back

Muscles use chemical energy from food to perform work, which is then transformed into mechanical energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What type of energy is involved in nuclear reactions?

Back

Nuclear energy is involved in nuclear reactions, such as fission and fusion.
