⚠️ Common Misconceptions
Misconception 1: "Holding a heavy object is doing physics work"
If the object does not move, no physics work is done — regardless of how tiring it feels. Work done = Force × distance. If distance = 0, work = 0. Your muscles are doing chemical work internally, but no mechanical work is done on the object.
Misconception 2: "Work done is the same as force"
Work done depends on BOTH force AND displacement in the direction of the force. A large force over a small distance can equal a small force over a large distance. They are completely different quantities: force is in Newtons, work done is in Joules.
Misconception 3: "Work is done when carrying a bag horizontally"
When you carry a bag at constant height, the lifting force (upward) is perpendicular to the direction of motion (horizontal). No work is done BY the lifting force on the bag's horizontal motion. (Work IS done by any horizontal force that moves you forward, but the bag's weight force does no work during horizontal movement.)
