Question

choose the correct answer. which of the following is true about work? work is when an object moves a distance in the opposite direction of the applied force. work is when an object moves a distance due to a specific force. work is when an object stays at the rest position.

Explanation:

• First option: Work (in physics) requires force and displacement in the same direction of the force (or component), so opposite direction is incorrect.
• Second option: By definition, work is done when a force causes an object to move a distance (in the direction of the force or its component). This matches the physics definition of work ($W = Fd\cos\theta$, where $F$ is force, $d$ is displacement, $\theta$ is angle between them; work occurs when $\theta$ allows a component of force to act along displacement).
• Third option: If an object stays at rest, displacement $d = 0$, so work $W = 0$ (no work is done).

Answer:

B. Work is when an object moves a distance due to a specific force.
