What is Mass, Weight and Average speed ?

Mass is the amount of inertia a body possesses. It is an intrinsic property of a body. It is constant all over the universe. It is measured in kg. Mathematically, 

                       $Mass = density \times volume$

Weight is the force with which a planet attracts a body towards itself. It is based on the gravity a planet possesses. It is measured in newtons. It varies from place to place depending on gravity. Mathematically, 

                          $Weight = mass \times gravitational \ acceleration $

$Speed = \frac{Total \ distance }{ Total \ time }$
