Forms of Energy & Transformation

Front

What is the energy of an object's position called?

Back

Potential energy is the energy stored in an object due to its position or state.

Front

What form of energy is related to the motion of atoms or molecules in a substance?

Back

Thermal energy is the energy that comes from the temperature of matter, related to the motion of its atoms and molecules.

Front

What energy transformation occurs when a student rubs their hands together rapidly?

Back

Chemical energy from food is transformed into mechanical energy (movement) and then into thermal energy (heat).

Front

Electrical Energy is transferred to which type of energy?

Back

Electrical energy is often transformed into thermal energy, as seen in devices like toasters.

Front

What type of energy is produced by vibrations?

Back

Sound energy is produced by vibrations that travel through the air or other mediums.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, depending on its mass and speed.

Front

What is mechanical energy?

Back

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

Front

What is an example of energy transformation in a light bulb?

Back

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

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food or fuel.

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.
