Answer
In physics, work is the energy transfer that occurs when a force causes displacement. It's defined mathematically as W = F × d × cos(θ) and measured in joules. Work can be:
- Positive: Force aids motion (lifting, pushing forward)
- Negative: Force opposes motion (friction, air resistance)
- Zero: No displacement or force perpendicular to motion
Work is a fundamental concept linking force, energy, and motion.
