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 x direction
?
What if 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)
?
