Work, Energy and Power — Syllabus & Topics
Topics covered in Work, Energy and Power for JEE Advanced Physics.
Topics in Work, Energy and Power
Work Done by Forces
- Work is done only when force causes displacement in its direction or has a component along displacement
- Work is a scalar quantity but can be positive, negative, or zero depending on angle between force and displacement
- For constant force: W = F⃗·S⃗ = FS cos θ, where θ is angle between force and displacement vectors
Kinetic Energy and Work-Energy Theorem
- Kinetic energy is energy possessed by a body due to its motion: KE = ½mv²
- Work-energy theorem: Net work done on a body equals change in its kinetic energy
- Theorem applies to both conservative and non-conservative forces
Potential Energy and Conservation Laws
- Potential energy exists only for conservative forces and represents stored energy
- Change in PE = negative of work done by conservative force: ΔU = -W_conservative
- Gravitational PE (near earth surface): U = mgh, reference at ground level
Types of Equilibrium
- Equilibrium occurs when net force is zero: F = 0, or dU/dx = 0
- Stable equilibrium: PE minimum, restoring force when displaced, d²U/dx² > 0
- Unstable equilibrium: PE maximum, destabilizing force when displaced, d²U/dx² < 0
