Energy Transformations Review

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit where the components are connected end-to-end, so that the current flows through each component in turn.

What type of energy is used to make turbines spin in a dam?

Back

Mechanical energy is the energy used to make turbines spin in a dam.

What happens to light when it passes through a straw in water?

Back

The straw appears bent because light is refracted, or bent, as it passes from air into water.

Front

What form of energy do photosynthesis and solar panels use?

Back

Photosynthesis and solar panels use light energy.

Front

What type of energy causes ice cream to melt?

Back

Thermal energy (or heat) causes ice cream to melt.

Front

What is energy transformation?

Back

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

Front

What is mechanical energy?

Back

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

Front

What is light energy?

Back

Light energy is a form of energy that is visible to the human eye and is produced by the vibrations of electrically charged particles.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, which is the total kinetic energy of particles in an object.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical circuit through which current can flow without interruption.
