Force
Lightning is a form of (blank) electricity.
Static
Energy is the ability to do (Blank), or cause a change in an objects position or potential.
Work
A mechanical wave needs something to move through to transfer energy. We refer to this "something" as the (blank)

Speed in a specific direction is called
Velocity
Objects like glass, ceramic, plastic are not considered good conductors so they are considered (blank)
Insulators
A generator converts (blank) energy into electrical energy.
Mechanical, Kinetic
Waves that vibrate perpendicular to the direction of the energy transferred are called.
Transverse waves
Dividing the distance an object moves by the time it takes to move give you it's (blank)
speed
A change in velocity over a period of time is called.
Acceleration
Silicon at room temperature does not conduct electricity but if enough heat is added it can conduct electricity. This makes is this type of material.

Parallel Circuit
Type of nuclear reaction used in power plants to produce energy by the splitting of atomic nuclei:
Nuclear fission
The amplitude in a sound wave tells you how (blank) the sound is.
Loud
In a series circuit with two light bulbs, if one light bulb burns out, what would happen to the other bulb?
