Unit 3 Review for FlashcardBowl

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and the square of its velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a stretched rubber band has potential energy.

Front

At what point in a swing's motion is kinetic energy the greatest?

Back

At the lowest point of the swing's motion.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy can be transformed from one form to another, but the total amount of energy remains constant.

Front

What type of energy is converted when heating water in a kettle?

Back

Chemical energy is converted to thermal energy and then to sound energy.

Front

What is an example of potential energy being converted to kinetic energy?

Back

A ball rolling down a hill is an example of potential energy being converted into kinetic energy.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in an object.

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 happens to energy when a car rolls down a hill?

Back

As the car rolls down the hill, its potential energy is converted into kinetic energy.

Front

What is sound energy?

Back

Sound energy is a form of energy that is associated with the vibration of matter. It is produced when an object vibrates.
