Law of Conservation of Energy

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.

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state.

Front

How does height affect gravitational potential energy?

Back

Gravitational potential energy increases with height; the higher an object is, the more potential energy it has.

Front

What is an example of energy transformation when a book falls?

Back

When a book falls, its energy transforms from kinetic energy to sound and heat energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object.

Front

What happens to the total energy in a closed system?

Back

In a closed system, the total energy remains constant according to the Law of Conservation of Energy.

Front

What is an example of kinetic energy in everyday life?

Back

A moving car or a running child are examples of kinetic energy.

Front

What is an example of potential energy in everyday life?

Back

A stretched rubber band or a book on a shelf are examples of potential energy.
