kinetic and potential energy

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 its velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

Front

How is gravitational potential energy calculated?

Back

Gravitational potential energy (PE) is calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, assuming no energy is lost to air resistance.

Front

What is the relationship between kinetic and potential energy in a roller coaster?

Back

In a roller coaster, potential energy is highest at the top of the hills and converts to kinetic energy as it descends.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).

Front

What type of energy is stored in a stretched rubber band?

Back

The energy stored in a stretched rubber band is potential energy.

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.

Front

Give an example of kinetic energy in everyday life.

Back

An example of kinetic energy is a moving car or a person running.

Front

What is an example of potential energy?

Back

An example of potential energy is a book on a shelf or a drawn bow.
