Exploring the Significance and Definition of Work in Physics and Engineering - starpoint
Yes, work can be negative. When a force acts opposite to the direction of motion, it does negative work. This is often the case in situations like breaking or stopping an object.
How is work related to power?
Reality: Energy is the capacity to do work, whereas work is the actual transfer of energy.
Myth: Energy and work are interchangeable terms.
While often used interchangeably, work and energy are distinct concepts. Energy is the capacity to perform work, whereas work is the actual transfer of energy. Think of it like money in a bank account (energy) vs. the act of spending it (work).
