Energy Test

Front

What is thermal (waste) energy?

Back

Thermal (waste) energy is the energy that is released as heat during a process, often considered a byproduct.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as an object held at a height.

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 chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like in batteries.

Front

What does it mean when energy is transformed?

Back

Energy transformation refers to the process of changing energy from one form to another, such as electrical energy to light 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

How does height affect potential energy?

Back

The higher an object is positioned, the more potential energy it has due to gravity.

Front

What happens to energy when a hammer hits a nail?

Back

The energy transforms from potential energy (when the hammer is raised) to kinetic energy (when the hammer strikes the nail).

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 the difference between thermal energy and heat?

Back

Thermal energy is the total energy of all particles in an object, while heat is the transfer of thermal energy from one object to another.
