Review 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.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as a ball held at a height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, such as a moving car or a flowing river.

Front

How does energy transform in a pendulum?

Back

In a pendulum, energy transforms from potential energy at the highest point to kinetic energy at the lowest point.

Front

What is gravitational energy?

Back

Gravitational energy is a form of potential energy that depends on an object's height and mass.

Front

Can energy change forms?

Back

Yes, energy can change forms, such as from potential to kinetic energy.

Front

What happens to energy in a closed system?

Back

In a closed system, the total energy remains constant; it can change forms but cannot be created or destroyed.

Front

What is an example of energy transformation in a car?

Back

In a car, chemical energy from fuel is transformed into kinetic energy as the car moves.

Front

What type of energy is sound?

Back

Sound energy is considered kinetic energy because it involves the movement of particles.

Front

What is thermal energy?

Back

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