Energy Transformations

Front

What does the Law of Conservation of Energy state?

Back

Energy cannot be created or destroyed, it can only be transformed.

Front

What is mechanical energy?

Back

Mechanical energy is the energy that is possessed by an object due to its motion or due to its position.

Front

What is chemical energy?

Back

Chemical energy is energy stored in matter because of its chemical bonds, released during a chemical reaction.

Front

Give an example of mechanical energy.

Back

A hammer, windmill, and wrecking ball are examples of mechanical 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 due to its motion.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, related to the motion of particles.

Front

What is radiant energy?

Back

Radiant energy is energy that travels in waves, such as light and heat.

Front

What is the difference between potential and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is energy of motion.

Front

What happens to energy in a closed system?

Back

In a closed system, the total amount of energy remains constant; it can change forms but is conserved.
