DESCRIPTORS OF MOTION

• Motion


  Constant shift in location with relation to a given reference point
• Frame of Reference


  Fixed and stationary object background used for comparing different positions of an object
• Scalar


  Fully described by magnitude only
• Vector


  Fully described by both magnitude and direction
• Magnitude


  Refers to the expressed quantitative measure of a standard unit
• Numerical value


  A number assigned to a quantity
• Distance


  The total length covered by a moving body
• Displacement


  Includes both the length and direction of objects from the starting point to its end point
• Speed


  Refers to how fast the object or body is moving
• Velocity


  Includes the direction of the objects or bodies take
• Acceleration


  Rate of change in velocity
• Positive acceleration moves faster
• Negative acceleration becomes slower or stops
• Velocity is also referred to as " speed with direction "
• Distance is a Scalar Quantity
• Displacement is a Vector Quantity
• Speed is a Scalar Quantity
• Velocity is a Vector Quantity
• Acceleration is a Vector Quantity
