SCIENCE =

• Vector Quantity


  Quantity that describes the magnitude and direction
• Distance


  Total path length travel by an object
• Scalar Quantity


  Quantities describing the magnitude of a measurement
• Speed


  Measure of how fast an object is travelling
• Formula for speed

  Speed = Distance / Time
• Velocity


  Rate of change in Velocity & Acceleration
• Uniform Acceleration


  Motion in which the velocity of an object changes at an equal amount of time
• Deceleration


  Slowing down or stopping of an Object
• Mechanical waves


  • Require a medium or matter to travel
• Electromagnetic waves


  • Don't require a medium or matter to propagate
• Amplitude


  Distance between two successive crest or trough
• Instantaneous speed


  How fast you are traveling at a given instant in time
• Speed


  The distance covered per time of travel
• Velocity


  Tells how fast an object is moving in a certain direction
• Amplitude


  The distance from midpoint to the crest or from midpoint to the trough of the wave
• Displacement


  The shortest length between two points and is fully described using magnitude and direction
• Graph


  Provides a quick view of information gathered
• Speedometer


  An instrument on a vehicle's dashboard indicating its speed
• Instantaneous velocity


  The velocity at any given instant
• Wavelength


  The distance between parts of the wave
• Perpendicular


  The direction of travel when vibrations are produced
• Medium


  The substance through which a wave can propagate
• Time


  The measurable period during which an action, process or condition exists or continues
• Instantaneous


  Existing or measured at a particular instant
• Scalar quantities are physical quantities that are fully described using the magnitude (number) and unit. Examples are time, mass, and distance.
• Vector quantities are described using the magnitude, unit, and direction. Examples of vector quantities are force, velocity, and acceleration.
• A motion diagram is a graphical illustration of an object in motion. This diagram qualitatively describes the movement of the object.
• The particle model representation of an object considers the actual size of the object as a single point.
• Constant speed means the object neither speeds up nor slows down.
• Constant velocity means the object is moving with constant speed in a constant direction.
• Instantaneous velocity is the velocity at any given instant.
• Acceleration is the rate of change in velocity.
• Waves radiate from a disturbance and can travel through solid, liquid, and gas, and some waves can even travel through empty space or vacuum.
• Transverse waves have vibrations perpendicular to the direction of travel.
• Longitudinal waves have vibrations parallel to the direction of travel.
• Compression is an area in the wave where there is high pressure due to particles being close together.
• Rarefaction is an area in the wave with low pressure due to particles being far apart.
• Mechanical waves require a medium to travel through.
• Electromagnetic waves can travel through a vacuum without a medium.
• Amplitude is the height of the wave, measured from the midpoint to the crest or trough.
