Science IFA #2 Review

Front

What happens to the total energy when an object falls?

Back

The total energy remains constant, but both kinetic and potential energy change.

Front

What color does an object appear if it absorbs all light waves?

Back

Black.

Front

In which direction does heat travel?

Back

Heat always travels from hot to cold.

Front

What does a prism do to white light?

Back

A prism refracts white light and splits it into seven different colors.

Front

What happens to light that is not transmitted through an object?

Back

Some is absorbed and some is reflected or refracted.

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object in motion.

Front

Define potential energy.

Back

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

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another.

Front

What is absorption in terms of light?

Back

Absorption is when an object takes in light energy and does not reflect or transmit it.
