Energy Transformations

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as from chemical energy to thermal energy.

Back

The energy conversion process in a hydroelectric dam is Potential energy to Kinetic energy to Electrical energy.

Front

What energy transformation occurs when a battery powers a flashlight?

Back

The energy transformation is from chemical energy to electrical energy to light energy.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as water stored in a dam.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, which is a measure of the kinetic energy of its particles.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules.
