Class 10 - Physics - Chapter 10 - Lecture 1 - 10.1 Simple Harmonic Motion (SHM) - Allied Schools

Allied Schools2 minutes read

Simple Harmonic Motion, as explained by Ryan Malik, involves vibratory motion with examples like a simple pendulum and a swing, where the net force, acceleration, and restoring force are all proportional to displacement and directed towards the position. The conditions for executing simple harmonic motion require a frictionless system with inertia and a restoring force, and in a system like a simple pendulum, energy oscillates between kinetic and potential energy.

Insights

  • Simple Harmonic Motion, as explained by Ryan Malik, involves vibratory motion where the net force is directly related to displacement, always pointing towards the equilibrium position.
  • To achieve Simple Harmonic Motion, a frictionless system with inertia and restoring force is necessary, and the energy in the system oscillates between kinetic and potential energy as the motion progresses.
