12.9 Energy Conversions and Types

Front

What is energy conversion?

Back

Energy conversion is the process of changing energy from one form to another, such as converting chemical energy in food to kinetic energy in movement.

Front

What are the main types of energy?

Back

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

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules, which can be released during a chemical reaction.

Front

How does energy flow in a circuit?

Back

Energy flows in a circuit from a power source (like a battery) as electrical energy, which can then be converted to other forms of energy, such as light or heat.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as gravitational potential energy or elastic potential energy.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons through a conductor.

Front

What is the energy conversion in a light bulb?

Back

In a light bulb, electrical energy is converted into light energy and thermal energy.

Front

What is the energy conversion in a hydroelectric power plant?

Back

In a hydroelectric power plant, kinetic energy from flowing water is converted into electrical energy.
