  • distance is the lenght between two points along a chosen path
    SI unit: m, symbol: s
  • displacement is the disstance covered in a straight line in a specific direction, measured in metres
    symbol: s, SI unit: m
  • speed is the distance covered per unit time, measured in metres per second (m/s), symbol: s
  • velocity is defined as distance travel per unit time, SI unit: m/s, symbol:v
  • acceleration is the change in velocity per unit time
    uniform acceleration-a moving body velocity or speed increase equally in time interval
  • uniform deceleration- when a body velocity or speed is decreases equally in time interval
  • Gradient= speed
    =y2 - y1/x2 - x1
  • Acceleration = gradient
  • Distance travelled= area under graph =½ ×b × h /l ×w× h
