First Law of Thermodynamics – so easy to understand?
Weight of any object is a force applied on the object by earth’s gravitational pull towards the center of the earth. We know the equation of a force = mass * acceleration. i.e. F=m*a…….(1) When we talk of weight force then the equation becomes like this: Weight(W)= mass * acceleration due to gravity
