Suppose force is applied on an object at an angle theta and the block moves for some distance along x axis
I understand that we take
x component of
force which is
Force cos theta and multiply it with
displacement vector. Why are we ignoring the
y component here? Is it because the block moves along
force is applied at an angle
theta to the ground and the block moves at an angle
gamma to the ground. What will be the work done then?
Should it be
F.d. cos (theta + gamma) ?
