What term describes the transfer of energy by applying a force to move a mass over a distance?

• A. Energy
• B. Acceleration
• C. Newton's First Law
• D. Work

Answer: (D)

Work is the transfer of energy that occurs when a force moves a mass over a distance. When you push an object and it travels in the direction of your push, energy is transferred to the object, often showing up as increased kinetic energy (and sometimes heat from friction). The amount of work is W = F · d (or W = F d cos theta), meaning positive when the force and motion align, negative when they oppose, and zero when the force is perpendicular to the motion. It’s helpful to keep in mind that energy is the capacity to do work, while work is the actual transfer of energy. Acceleration describes how velocity changes, and Newton's First Law describes inertia and how forces relate to motion, not the transfer of energy itself.
