What is the standard formula for work in physics?

• A. Work = Energy / Time
• B. Work = Power × Time
• C. Work = Force × Distance
• D. Work = Mass × Velocity

Answer: (C)

Work is the energy transferred to an object by a force as it moves. The amount of work depends on how strong the force is and how far the object moves in the direction of that force. When the force acts along the path of the motion, the work is simply the product of force and distance: W = F × d. If the force isn’t exactly in line with the motion, you use the component of the force in the direction of motion, giving W = F d cos θ. That makes the standard relation clear: force times distance (for a force aligned with the displacement) is the foundational formula for work. Other expressions touch on related ideas—like power, which is work per unit time, or energy divided by time, which isn’t a work formula—so they don’t replace the basic W = F × d relation.
