Energy Checkpoint Flashcard

Front

What is energy conversion?

Back

Energy conversion is the process of changing energy from one form to another, such as converting electrical energy into mechanical energy.

Front

What type of energy does a rechargeable battery store?

Back

A rechargeable battery stores chemical energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object, enabling it to do work.

What happens to electrical energy in a clothes dryer?

Back

In a clothes dryer, electrical energy is converted into heat energy to dry the clothes.

Front

What are compressions and rarefactions in a longitudinal wave?

Back

Compressions are regions where particles are close together, and rarefactions are regions where particles are spread apart.

Front

What is kinetic energy?

Back

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

Front

What is chemical potential energy?

Back

Chemical potential energy is the energy stored in the bonds of chemical compounds, like batteries.

Front

How does energy transfer in a wave?

Back

Energy is transferred in a wave through the oscillation of particles in the medium.

Front

What happens to the speed of a wave when it moves from air to water?

Back

The speed of the wave increases when it moves from air to water.

Front

What is the principle of conservation of energy?

Back

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