What are the three ways to calculate work?

Answer
Three primary methods to calculate work:
- Direct formula: W = F × d × cos(θ) - for constant force
- Work-Energy Theorem: W = ΔKE = ½m(v₂² - v₁²)
- Integration: W = ∫F·ds - for variable force
Each method suits different scenarios: constant vs. variable force, known velocities vs. known forces.
