Energy Transformations

Front

What is energy transformation?

Back

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

Front

What are the main types of energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as KE = 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 gravitational potential energy.

What happens to energy in a light bulb?

Back

In a light bulb, electrical energy is transformed into thermal energy (heat) and light energy.

Front

At which point in a pendulum's swing is potential energy highest?

Back

Potential energy is highest at the highest points of the swing (points 1 and 4).

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is fission?

Back

Fission is the process of splitting a large atomic nucleus into smaller nuclei, releasing a significant amount of energy.

Front

What is fusion?

Back

Fusion is the process of combining two light atomic nuclei to form a heavier nucleus, releasing energy, as seen in stars.

Front

What is thermal energy?

Back

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