What is mechanical energy?

Back

Mechanical energy is the energy that an object has due to its motion or position. It is the sum of kinetic energy (energy of motion) and potential energy (stored energy).

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It is used to power devices like lights, computers, and appliances.

What is thermal (heat) energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in an object.

What happens to energy during a transformation?

Back

During a transformation, energy changes from one form to another, but the total amount of energy remains constant (Law of Conservation of Energy).

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 is an example of energy transformation in a blender?

Back

In a blender, electrical energy is transformed into mechanical energy to mix or chop food.

Front

What is an example of unwanted energy transformation?

Back

An example of unwanted energy transformation is when electrical energy in a circuit is converted into heat energy, causing the wires to get hot.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. The faster an object moves, the more kinetic energy it has.

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a book on a shelf has gravitational potential energy.
