Review on Potential and Kinetic Energy/Transformation of Energy

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. For example, a rock at the top of a hill has potential energy because of its height.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What does the Law of Conservation of Energy state?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

Give an example of energy transformation.

Back

When a light bulb is turned on, electrical energy is transformed into light energy and thermal energy.

Front

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 the relationship between potential and kinetic energy?

Back

Potential energy can be transformed into kinetic energy and vice versa, depending on the object's position and motion.

Front

What is an example of high potential energy?

Back

A roller coaster at the top of a hill has high potential energy due to its height.

Front

What is an example of high kinetic energy?

Back

A speeding car has high kinetic energy due to its fast motion.

Front

What happens to the total energy in a closed system?

Back

The total energy in a closed system remains constant, even as energy transforms between potential and kinetic forms.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground, calculated as weight times height.
