🛠️ Positive vs Negative Work – Explained Work in physics is done when a force causes displacement of an object. The sign of the work (positive or negative) depends on the direction of the force relative to the displacement. --- ✅ Positive Work: Happens when the force and displacement are in the same direction. The force adds energy to the object. Example: Lifting a box upward, pedaling a bicycle forward, or pushing a cart forward. W = F d cos theta If , then → Work is positive --- ❌ Negative Work: Happens when the force and displacement are in opposite directions. The force removes energy from the object (slows it down). Example: Friction acting against motion, or gravity acting when an object is lifted. If , then → Work is negative --- ⚖️ Summary Table: Type of Work Force Direction Effect on Object Sign Positive Work Same as displacement Adds energy / speeds up + Negative Work Opposite to displacement Removes energy / slows down – --- 🧠 Quick Tip: If a force helps the motion → Positive Work If a force opposes the motion → Negative Work #PositiveWork #NegativeWork #PhysicsBasics #WorkAndEnergy #ForceAndMotion #PhysicsLovers #STEMEducation #ScienceExplained #MechanicalWork #PhysicsConcepts
