Mechanical energy Conservation of Energy

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.

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

When is kinetic energy at its maximum on a roller coaster?

Back

Kinetic energy is at its maximum at the lowest point of the roller coaster, where the speed is highest.

Front

What happens to energy in a pendulum as it swings?

Back

As a pendulum swings, potential energy is converted to kinetic energy and vice versa, but the total mechanical energy remains constant.

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting wind energy into electrical energy.

Front

What type of energy is associated with the position of an object?

Back

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

Front

What type of energy is associated with motion?

Back

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

Front

What is nuclear energy?

Back

Nuclear energy is the energy released during nuclear fission or fusion, often associated with the splitting of atoms.

Front

What is an example of energy conservation?

Back

Energy conservation refers to the practice of reducing energy use, such as turning off lights when not in use.

Front

What is the highest point of a swinging pendulum called?

Back

The highest point of a swinging pendulum is called the amplitude.
