Teaching notes:

  • There must be a reference point to describe the position of the given body.
  • Distance ≥ Displacement.
  • Distance is a scalar quantity and Displacement is a vector quantity.
  • The physical quantities which are described by only magnitude are called scalar quantities.
  • The physical quantities which are described by both magnitude and direction are called as vector.
  • Average velocity =  (Total dispalcement)/(Total time.)
  • Instantaneous velocity is defined as the velocity at that particular time (second).
  • When the velocity of a body decreases with time, then acceleration is called retardation or negative accelearation.
  • The acceleration of a freely falling and vertically projected bodies is called acceleration due to gravity.
  • The value of acceleration  due to gravity changes w.r.t height, depth , at equator and at poles.
  • The standard value of acceleration due to gravity on Earth is 9.8 m/s2.
