motion, forces, and energy

W = FS cos q If the displacement S is in the direction of the force F, q = 0, cos q =1 Then, W = FS x 1 W = FS If q = 90 o , cos 90 o = 0 Therefore, W = FS x 0 = 0 i.e, no work is done by the force on the body. If a stone tied at the end of a string is whirled around i..

In many cases when we pull or push an object, we find that force and displacement are not in the same direction. Let a constant force F acting on a body produce a displacement S as shown in the figure. Let q be the angle between the directions of the force and displace..
