Work, Force and Motion
This word is defined as a push or pull on an object.
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)
Medium
Sound can travel through all of these except for:
a) brick wall
b) vacuum
c) water
d) air
b) vacuum
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.
Semiconductor
Another word for "Heat" energy is (Blank)
Thermal
Waves that move energy parallel to the direction of the vibration of the medium are called this:
Longitudinal wave
What happened on December 7th, 1941 that had a huge impact on the U.S. and the rest of the world?
Pearl Harbor
The tendency of an object to resist changes in motion.
Inertia
Transistors are semiconductors used to:
a) lower the resistance of a magnetic signal
b) to create a magnetic signal
c) amplify electrical signals
d) insulate an electrical signal
c) amplify electrical signals
An electric motor converts (blank) energy into (blank) energy.
Electrical into Mechanical/Kinetic
The frequency of sound wave determines the (blank) of the sound.
The pitch
Type of circuit that only allows the flow of electricity along one path.
Series
Work is only done on an object when a (blank) is applied to the object and the object has to (blank) a distance.
Force, Distance
Type of electrical circuit where electricity can flow in multiple paths
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?
It would not burn
