Forms of Energy & Transformations

Front

What is Mechanical Energy?

Back

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

Front

Define Kinetic Energy.

Back

Kinetic Energy is the type of energy an object has because of its motion. Examples include a moving car, a flying baseball, or flowing water.

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. For example, a pulled back rubber band or water stored in a dam.

Front

What form of energy is produced by moving electrons?

Back

Electrical Energy is produced by moving electrons and is used to power devices like lights and computers.

Front

What is Thermal 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.

Front

What is Chemical Energy?

Back

Chemical Energy is the energy stored in the bonds of chemical compounds, like food or batteries, which can be released during a chemical reaction.

Front

What is Radiant Energy?

Back

Radiant Energy is the energy of electromagnetic waves, such as light energy from the sun.

Front

How does energy transformation occur?

Back

Energy transformation occurs when energy changes from one form to another, such as when potential energy is converted to kinetic energy.

Front

Give an example of energy transformation in a windmill.

Back

In a windmill, kinetic energy from the wind is transformed into mechanical energy to turn the blades, which can then generate electrical energy.

Front

What is the relationship between potential and kinetic energy?

Back

Potential energy can be converted into kinetic energy. For example, when a roller coaster descends, its potential energy decreases while its kinetic energy increases.
