WebThe work done by a constant force of gravity on an object depends only on the object’s weight and the difference in height through which the object is displaced. Gravity does negative work on an object that moves upward ( y B > y A ), or, in other words, you must do positive work against gravity to lift an object upward.

WebWhen work done by force of gravity is negative (Assume only gravitational force to be acting). This question has multiple correct options. WebThe g-force experienced by an object is due to the vector sum of all non-gravitational forces acting on an object's freedom to move. In practice, as noted, these are surface-contact forces between objects. Such forces cause stressesand strainson objects, since they must be transmitted from an object surface. hunters of diamona
