📖 The Physics Definition of "Work"
In everyday language, holding a heavy box is "hard work." But in physics, if the box doesn't MOVE, you've done ZERO work! Work requires both force AND movement in the direction of the force. Push a car 10 metres and you've done work. Hold a car stationary for an hour and — despite being exhausted — you've done no physics work at all. Work is the bridge between forces and energy: work done = energy transferred.
