Everybody, when free, falls towards the centre of earth with an acceleration = g , which is called acceleration due to gravity. The value of g on the surface of earth is, g = (GM)/(R^(2)) = 9.8 m//s^(2) . It is a vector, directed always the centre of earth. The value of g does not depend upon shape, size or mass of the body. Rether, it depends on mass and size of earth (or planet due to which there is a gravity pull). Read the above passesge and answer the following questions : (i) A piece of stone and a feather are dropped together in space from the same height. which one will strike the ground first ? (ii) The mass of a planet is (1)/(8)th the mass of earth and its diameter is (5)/(6) the diameter of earth. What is the value of 'g' on the surface of this planet. (iii) What does the concept of free fall imply in day to day life?
