Big Idea 10 and 11

Front

What is reflection of light?

Back

Reflection of light is when light bounces off a surface, such as a mirror, allowing us to see images.

Front

What is absorption of light?

Back

Absorption of light occurs when a surface takes in light energy, preventing it from being reflected or transmitted.

Front

What is insulation in electrical safety?

Back

Insulation is a material that prevents the flow of electricity, protecting individuals from electric shocks.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter; it is the energy of moving particles.

Front

What happens to light when it passes from air into water?

Back

When light travels from air into water, it bends due to a change in speed, a phenomenon known as refraction.

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object or system to another, such as when a basketball is spun.

Front

What is the purpose of a circuit?

Back

A circuit is a closed loop that allows electricity to flow, powering devices like lights and appliances.

Front

What is the role of a mirror in reflecting light?

Back

A mirror reflects light by bouncing it off its smooth surface, allowing us to see our reflection.

Front

What is the difference between light and thermal energy?

Back

Light energy is visible and allows us to see, while thermal energy is related to heat and temperature.

Front

What is an example of energy causing motion?

Back

Spinning a basketball on your finger is an example of energy being applied to create motion.
