Energy Transformations Flashcard 4.2

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What happens to the total energy in a closed system during an energy transformation?

Back

The total energy remains constant in a closed system during an energy transformation.

Front

Define kinetic energy.

Back

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

Front

Define gravitational potential energy.

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field.

Front

What is an example of energy transformation in a battery-operated device?

Back

In a battery-operated radio, chemical potential energy is transformed into electrical energy, which is then transformed into sound energy.

Front

What happens to gravitational potential energy as an object falls?

Back

As an object falls, its gravitational potential energy decreases while its kinetic energy increases, keeping the total energy constant.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on an object's position, while kinetic energy is the energy of an object in motion.

Front

What type of energy transformation occurs in a light bulb?

Back

In a light bulb, electrical energy is transformed into light energy and thermal energy.

Front

How does energy transfer occur during a collision?

Back

During a collision, energy is transferred from one object to another, but the total energy of the system remains the same.

Front

What is an example of elastic potential energy?

Back

An example of elastic potential energy is the energy stored in a stretched rubber band.
