Important one liner (Time and speed)

  • Speed is the distance covered per unit time.
  • Distance equals speed multiplied by time.
  • Time equals distance divided by speed.
  • Average speed is total distance over total time.
  • Instantaneous speed is the speed at a given moment.
  • Relative speed in opposite directions adds both speeds.
  • Relative speed in same direction subtracts speeds.
  • Uniform speed means constant speed.
  • Non-uniform speed varies over time.
  • SI unit of speed is meters per second (m/s).
  • SI unit of time is second (s).
  • SI unit of distance is meter (m).
  • To convert m/s to km/h multiply by 3.6.
  • To convert km/h to m/s divide by 3.6.
  • Zero speed means no movement.
  • Higher speed covers more distance in same time.
  • Lower speed takes more time for same distance.
  • Speed-time graph shows speed variation over time.
  • Distance-time graph shows how far an object travels over time.
  • Acceleration is rate of change of velocity over time.
  • Deceleration is negative acceleration.
  • In constant acceleration, speed changes linearly with time.
  • Average velocity considers direction; speed does not.
  • Graph area under speed-time curve gives distance.
  • Speed of light in vacuum is approximately 3×10^8 m/s.
  • Speed limits are legal maximum speeds on roads.
  • Time dilation occurs at relativistic speeds.
  • Terminal velocity is the constant maximum speed in fluid.
  • Angular speed measures rotation per unit time.
  • Linear speed relates to angular speed by radius.
