The movement of energy from one item to another

Moving electrons

The force that makes electricity flow through a wire

A closed loop in which charges can continuously move.

A tool used for measuring the difference (voltage) between 2 points in an electrical circuit.

1. Measure of opposition to an electric current

2. Increase sound

Direct- (DC) The electric charge or current only flows in one direction

Alternating- (AC) The electric current changes direction periodically

Conductor- Allows electric current to flow freely (metals)

Insulator- Protects us from the dangerous effects of electricity flowing through a circuit (Glass, plastic)

A change in the direction of waves when they bounce off a barrier.

They do not require a medium; can travel through air, solid materials, and even space!

- Vibrations are perpindicular ( up and down) to the direction of travel

- waves in water, light waves

number of waves passing a certain point in a specific amount of time; Hertz

A change in the direction of waves as they pass from one medium to another.

The distance a wave travels in a specific amount of time

- Waves in which particles move left and right

- Sound waves and P- waves

Pitch- the rate at which vibrations are produced

- A high pitch sound cooresponds to a high frequency sound wave and a low pitch cooresponds to a low frequency sound wave

Medium- what a wave travels through

water

The Great Wall of China

Honey

Elephants!

Carotenoids in their food!
