Question

hello, does the argument of Prof.Lewin in L.7 propose a new ,general, definition of weight of an object by which "w" is not always =mg;rather it depends on the acc. of the system the object's in?

Answer 1

w related as an effect due to the attraction of 2 bodies by gravity is the typical approach, but what if a new relation arises if in a reference frame, a body is approached by another carrying a constant acceleration? without a gravimeter the effect on both cases would be indistinguishable (if there are no dampening forces)

Answer 2

ts true because what is actually weight, the force with which the body is pulled towards the earth or else F=ma where a=g in case of earth here g is nothing but the acceleration attained by the body if it is let free. if u consider there is no gravitational force and there is some force in a region the that tries to full the body with some acceleration then in that case wis not equal to g but the acceleration with which its being pulled

Answer 3

thanks for your help guys.
