Answer:
Every body (mass) which is under acceleration, will definitely have a force associated with it that causes the acceleration, which is clearly explained by Newton’s Second law (F=ma).We know that on earth every object is under the influence of a gravitational field which makes every body on earth subjected to gravitational acceleration (g=9.81 m/s2)Thus a force should always be exerted in the direction of acceleration, i.e. towards the centre of the earth.This is the force which we always feel acting towards the ground and we have termed that force as weight (W)!Thus F=ma becomes W=mg. Thus weight on a body of mass 1 Kg is W=1 x 9.81 Kg-m/s2 which is equal to 9.81 N.
