Energy and Energy Transformations

Front

What is the definition of energy?

Back

Energy is the ability to cause change.

Front

What are the two main types of mechanical energy?

Back

Potential energy and kinetic energy.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is the relationship between potential energy and kinetic energy?

Back

They have an inverse relationship; as one increases, the other decreases.

Front

What type of energy transformation occurs in a music player?

Back

Chemical energy is transformed into electrical energy, which is then transformed into sound energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object.

Front

What is an example of energy transformation in a roller coaster?

Back

As the coaster climbs, kinetic energy is converted to potential energy; as it descends, potential energy is converted back to kinetic energy.

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves.
