Module 6
Tells you how quickly and in what direction an object is moving in relation to a reference point.
What is velocity.
A push or pull that acts on an object
What is force?
The ability to do work
What is energy?
Any speed that is faster than the speed of sound in the medium of interest
What is Supersonic speed?
The electromagnetic spectrum that the human eye can see.
What is visible light?
A point against which motion is measured.
What is Reference point?
The weakest of the four fundamental forces.
What is gravitational force?
(True or False) Lightning is five times hotter than the sun.
What is true?
(True or False) Sound can extinguish fire/.
What is True
The transfer of energy by speacial waves
What is electromagnetic radiation?
The distance an object travels plus the direction from the starting point.
What is Displacement ?
When an object is acted on by one or more unbalanced forces, the net is equal to the object times the resulting acceleration.
What is Newtons second law of motion?
Energy cannot be created nor destroyed; it can only be converted from one form to another or transferred from one object to another.
What is the Law of Conservation of Energy?
The measurement in which sound is measured.
What is dB?
When the crest of one wave overlaps another wave.
What is Constructive Interference?
Distance/time or d/t
What is the formula for speed?
Ancient Greek Philospher (384-322 BC)

German Born English Astronomer who discovered infared radiation.
Who was William Herschel?
The rate at which an object is moving at a given moment in time.
What is instantaneous speed?
When air resistance and weight become equal.
What is Terminal Velocity? (Daily Double)
1/2 x m x v2
What is the formula for Kinetic Energy
What is the tympanic membrane?
Light waves from the sun that vibrate in all directions.
What is unpolarized lights?
