Which scenario best describes zero work being done?
Holding a suspended weight without moving it
In physics, work equals force multiplied by the displacement moved in the direction of that force: \(W = F \times d\).
If the displacement is zero, then no matter how large the force, the work done is zero.
Holding a suspended weight steady applies an upward force, but the weight does not move, so the displacement is zero and the work is zero.
Lifting, pulling up a load and pushing a trolley all involve movement, so each does non-zero work.
Hence, the answer is holding a suspended weight without moving it.
