Term
 Collision that two objects stick together.  Move with the same velocity after collision.
Definition
 Perfectly Inelastic
Term
 Collision conserves both TOTAL MOMENTUM and TOTAL KINETIC ENERGY.  Objects seperate after collision.
Definition
 Elastic
Term
 After collision, objects are deformed, and lose kinetic energy.
Definition
 Inelastic
Term
 The time it takes to complete a cycle of motion
Definition
 Period
Term
 Number of cycles or vibrations per unit of time.
Definition
 Frequency
Term
 What kind of wave has a single nonperiodic disturbance?
Definition
 Pulse wave
Term
 At a fixed boundary, waves are
Definition
 Reflected and inverted
Term
 When a light wave travels from a medium with a lower refractive index to a medium with a higher refrective index, the light wave will bend ________ the normal? For example AIR (1) to WATER (1.33)
Definition
 Towards
Term
 When a light wave travels from a medium with a higher refractive index to a medium with a lower refrective index, the light wave will bend _______ the normal? For example GLASS (1.66) to WATER (1.33)
Definition
 Away from
Term
 A wave whose displacement has a periodic variation with time or distance, or both.
Definition
 Periodic Wave
Term
 What is a sine wave?
Definition
 A geometric waveform that oscillates (moves up, down or side-to-side) periodically, and is defined by the function y = sin x. In other words, it is an s-shaped, smooth wave that oscillates above and below zero.
Term
 A moving wave that consists of oscillations occurring perpendicular (or right angled) to the direction of energy transfer.
Definition
 A transverse wave
Term
 Objects seperate after collision.  Momentum and Kinetic Energy both conserved
Definition
 Perfectly Elastic
Term
 A measurement of the top (or bottom) half of the wave.
Definition
 Amplitude
Term
 What happens when a rubber rod is rubbed with a piece of fur giving it a negative charge?
Definition
 Electrons are added to the rod
Term
 Atmospheric refraction of light is responsible for?
Definition
 Mirages
Term
 If a positively charged glass rod is used to charge a metal bar by induction,
Definition
 The charge on the bar must be negative
Term
 What is charging by contact?
Definition
 When a charged object touches another object. Electrons can be transferred through friction. Electrons can also be transferred through contact and conduction. You can charge a neutral object by contact with a charged object. Charging by contact happens when electrons move from one object to a neutral object.
Term
 What is induction?
Definition
 Charging by induction is an alternate charging method, which does not involve physical contact between to objects. Instead, this process involves bringing an object with a net electric charge sufficiently close to, but not in contact with, a second neutral object. As the charged object approaches, it causes an electric polarity within the neutral object. The type of polarity depends on the type of charge that is dominant in the charged object. Because like charges repel and unlike charges attract, if the charged object is negative, then the side of the neutral object nearest to the negatively charged object will become positively charged.   Require something like a conductor (ex. METAL)
Term
 What is charging by polarization?
Definition
 Electrically polarized objects develop electric charges. There are at least superficial charges and in some cases volumetric charges. The sum of the total charge in the body is zero so there are positive regions and negative regions.   Can occur with an insulator (ex. Wood)
Term
 What kind of wave is a sound wave?
Definition
 Longitudinal
Term
 What happens in a two body collision?
Definition
 Momentum is conserved
Term
 At a free boundary, waves are
Definition
 reflected but not inverted
Term
 The Doppled effect occurs in what kind of waves?
Definition
 ALL waves
Term
 What portion of the electromagnetic spectrum is used in a microscope?
Definition
 VISIBLE light
Term
 What portion of the electromagnetic spectrum is used to sterilize medical equipment?
Definition
 Ultraviolet Light
Term
 Which portion of the electromagnetic spectrum is used in a television?
