Force acting over a distance is the definition of:

Force acting over a distance is the definition of:

• A. Kinetic energy.
• B. Work.
• C. Latent energy.
• D. Potential energy.

Answer: (B)

This question tests how you understand work. Work is the transfer of energy that occurs when a force moves an object through a distance in the direction of the force. The amount of work done is W = F × d × cos(theta), meaning you multiply the force by the distance moved and by the cosine of the angle between the force and the displacement. If the force isn’t aligned with the motion, only the component along the direction of movement contributes to work. If there’s no movement, no work is done, even if you’re applying a force. This idea is different from kinetic energy (the energy of motion you already have) and from potential energy (energy stored due to position). Latent energy isn’t part of this framework; it’s a concept tied to phase changes rather than work done over distance.
