Changing the angle of the force to the direction of motion would increase the work done by the same force.

Explanation:

The expression for work is #W=Fs cos theta#.

When the angle is #0^o# the work done by a given force is maximum, when the angle is #90^o# the work is #0#.

Reducing the angle increases the work done.
