Topics in Simple Harmonic Motion
1
Introduction and Basic Concepts of SHM
- SHM occurs when restoring force F = -kx acts on a particle
- The motion is characterized by periodic oscillation about mean position
- Amplitude (A) is the maximum displacement from mean position
2
Displacement Equations and Energy in SHM
- Velocity-displacement relation: v = ±ω√(A² - x²)
- v-x graph is an ellipse with maximum velocity ωA at mean position
- Total mechanical energy E = ½mω²A² (constant throughout motion)
3
Time Equations and Graphical Analysis
- Standard time equations: x = A sin(ωt + φ) or x = A cos(ωt + φ)
- Choice of equation depends on initial conditions at t = 0
- Phase constant φ determined by initial position and velocity
4
SHM and Uniform Circular Motion
- SHM is projection of uniform circular motion on any diameter
- Particle moving in circle with constant ω gives SHM projection
- Amplitude of SHM equals radius of circular motion
Key Concepts
SHM occurs when the restoring forceThe general solution is x =Velocity v = ±ω√(A²Total mechanical energy E = ½mω²A²For small angles (θ < 15°)
