Question

when the work done by a force zero

Answer 1

if there is no displacement or movement even after applying a great force,then no work is said to be done in spite of all the effort.
example:a boy pushing a wall

Answer 2

Answer:

Explanation:

Since dtdx=0, the force is always perpendicular to its velocity. The item moves in a way that keeps the force's application location constant (dx=0).

ZERO WORK: When force and displacement are perpendicular to one another or when either force or displacement is zero, the work performed is said to be zero work. Example: When we walk while holding an object, the force operates below while the displacement acts forward.
