Energy and Energy Transformations

Front

What is Mechanical Energy?

Back

Mechanical Energy is the total energy of motion and position, which is the sum of Kinetic Energy (energy of motion) and Potential Energy (stored energy).

Front

What is Electromagnetic (EM) Energy?

Back

Electromagnetic (EM) Energy is energy transmitted through space in the form of electromagnetic waves, such as light and radio waves.

Front

What does it mean that energy cannot be created or destroyed?

Back

It means that energy can only change forms, such as from potential energy to kinetic energy, but the total amount of energy remains constant.

Front

What type of energy is found in food?

Back

Chemical Energy is the type of energy that comes from the food you eat, which is stored in the chemical bonds of the food molecules.

Front

What is Electrical Energy?

Back

Electrical Energy is the energy that comes from the motion of charged particles, such as electrons.

Front

What is Kinetic Energy?

Back

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

Front

What is Potential Energy?

Back

Potential Energy is the stored energy of an object due to its position or state, such as a rock at the top of a hill.

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 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

What is Nuclear Energy?

Back

Nuclear Energy is the energy released during nuclear reactions, such as fission or fusion, involving the nucleus of an atom.
