Post-Test: Unit 2-Transformation of Energy

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting kinetic energy to potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its 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 in an object due to its position or state, such as gravitational potential energy.

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 mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work.

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 chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, released during a chemical reaction.

Front

What is electrical energy?

Back

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

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves, which can be heard by the human ear.

Front

What is light energy?

Back

Light energy is the energy that is visible to the human eye, produced by electromagnetic radiation.
