Understanding Energy Conservation Concepts

Front

What is the primary form of energy conversion that occurs in a battery when it powers an electrical circuit?

Back

Chemical energy to electrical energy

Front

What type of energy transformation occurs when a roller coaster car rolls down to the bottom of a hill?

Back

Gravitational to mechanical to thermal to sound energy

Front

What principle states that energy cannot be created or destroyed?

Back

Energy conservation principle

Front

How is energy conserved in a closed system, such as an amusement park ride?

Back

Energy is transformed from one form to another, with total energy remaining constant.

Front

During photosynthesis, what type of energy do plants convert radiant energy into?

Back

Chemical energy stored in glucose.

Front

What is the definition of kinetic energy?

Back

The energy of an object due to its motion.

Front

What is potential energy?

Back

The energy stored in an object due to its position or configuration.

Front

What is the law of conservation of energy?

Back

The total energy in a closed system remains constant; energy can only change forms.

Front

What is an example of energy transformation in a hydroelectric power plant?

Back

Potential energy of water is converted to kinetic energy, then to electrical energy.

Front

What type of energy transformation occurs in a light bulb?

Back

Electrical energy is transformed into light and thermal energy.
