WebOct 16, 2024 · - Work done is zero when either force or displacement is zero. Examples of zero work - - A man trying to push a wall - Blocking sliding over smooth surface - Sitting in a chair - Work done in circular motion - Car running over frictionless surface - A man standing still - Porter carrying load on his shoulder - An object wandered in space. WebThat's right, you can do work less than zero, in physics. Let's find out how. Now in a previous video, we saw how to calculate work. It's calculated as force acting on an object multiplied by the displacement of that object. This means that to do work, in physics, you need to push or pull on something, and while pushing or pulling, you have to ...

WebSolution Verified by Toppr Work done (W) = force ∗ displacement. Hence, work is said to be done when there is displacement. In this case the wall does not displace from its position even though the force is applied and since displacement is zero work done is said to be zero.
