What is the primary difference between energy and work?

• A. Energy is always transformed, while work is not
• B. Energy is the capacity to do work, while work is the process of energy transfer
• C. Energy can be created, while work cannot
• D. Energy is measured in joules, but work is not

Answer: (B)

The primary difference between energy and work is that energy is defined as the capacity to do work, while work signifies the process through which energy is transferred from one system to another. Energy exists in various forms, such as kinetic, potential, thermal, and more, representing a system's ability to perform actions or produce change. When energy is utilized to perform an action, such as moving an object, that action is quantified as work. In this context, work is calculated as the force applied to an object times the distance over which that force is exerted, and it results from the interaction between energy forms. The transfer of energy via work can occur in various scenarios, such as lifting an object against gravity, moving a car, or even compressing a spring. Understanding this distinction highlights how energy and work are fundamentally interconnected yet serve different roles in physics.
