Simple Harmonic Motion — Syllabus & Topics
Topics covered in Simple Harmonic Motion for NEET-UG Physics.
Topics in Simple Harmonic Motion
Fundamentals of Simple Harmonic Motion
- SHM is oscillatory motion where restoring force F = -kx (proportional to displacement)
- All SHM is periodic, but not all periodic motion is SHM
- Displacement equation: x = A sin(ωt + φ) or x = A cos(ωt + φ)
Velocity and Acceleration in SHM
- Velocity v = dx/dt = Aω cos(ωt + φ) = ±ω√(A² - x²)
- Maximum velocity occurs at mean position: vₘₐₓ = Aω
- Velocity is zero at extreme positions
Energy in Simple Harmonic Motion
- Total mechanical energy E = ½kA² = ½mω²A² (constant)
- Potential energy U = ½kx² = ½mω²x² (varies with position)
- Kinetic energy K = ½mv² = ½mω²(A² - x²) (varies with position)
Simple Pendulum
- Ideal simple pendulum: point mass suspended by massless, inextensible string
- For small angles (θ < 10°): T = 2π√(l/g)
- Time period independent of mass and amplitude (for small oscillations)
