Forms of Energy

Front

What is energy transformation?

Back

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

Front

What are the main forms of energy?

Back

The main forms of energy include kinetic, potential, thermal, chemical, electrical, and nuclear energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as 1/2 mv², where m is mass and v is velocity.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, calculated as mgh, where m is mass, g is acceleration due to gravity, and h is height.

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.

How does an alarm clock transform energy?

Back

An alarm clock transforms electrical energy into mechanical energy (to move the hands) and sound energy (to produce the alarm sound).

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, often perceived as heat.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases with height; the higher an object is, the more gravitational potential energy it has.

Front

What is an example of chemical energy?

Back

Chemical energy is stored in the bonds of chemical compounds, such as in food or batteries.

What happens to energy in a car crash?

Back

In a car crash, kinetic energy is transformed into other forms of energy, such as sound, heat, and deformation of car parts.
