The amount of work done by a person pressing against a rigid wall is zero. Work is defined as the product of force and displacement in the direction of the force. In this case, since the wall is rigid and not moving, there is no displacement in the direction of the force applied by the person. Therefore, the work done is zero.
Mathematically, the formula for work (W) is given by:[tex][ W = F \cdot d \cdot \cos(\theta) ][/tex]
where:
( W ) is the work done,
( F ) is the force applied,
( d ) is the displacement,
and
[tex]( \theta )[/tex] is the angle between the force and the direction of displacement.In this scenario,
( d ) is zero (no displacement),
so the work done (( W )) is zero.

The wall will have no change in motion when the force is applied hence the displacement would be =0

Hence
W=F*S
Therefore
W=F*0
W=0Jules
