    Study Notes

    Simple Harmonic Motion (SHM) and Pendulum Behavior

    • The speed of the bob increases as it moves towards point B from O due to the conversion of potential energy into kinetic energy.
    • In SHM, the acceleration of the object is always directed towards the mean position and is proportional to the displacement from that position.
    • A key feature of a body executing SHM is that it vibrates about an equilibrium position and its motion is periodic.
    • The time period of a pendulum in SHM is defined as the time taken for one complete cycle of motion.
    • In SHM, the acceleration is directly proportional to the negative displacement from the mean position, illustrating Hooke's Law.
    • The period of a pendulum is independent of mass and amplitude because it primarily depends on the length of the pendulum and the acceleration due to gravity.
    • The time period of a simple pendulum is dependent on its length and the acceleration due to gravity (g).
    • The frequency of a vibrating body is defined as the number of complete cycles of motion occurring in one second.
    • The maximum displacement from the mean position in SHM is referred to as the amplitude.

    Waves and Oscillation

    • In transverse waves, particles of the medium vibrate perpendicular to the direction of wave propagation.
    • Mechanical waves, such as sound waves, require a medium (solid, liquid, or gas) for their propagation.
    • The speed of a wave is equal to the product of its frequency and wavelength.
    • For an object to oscillate with SHM, it must experience a restoring force that is directly proportional to the displacement from its equilibrium position.
    • Increasing the length of a simple pendulum results in an increase in the time period (T), making it swing more slowly.
    • Damping refers to a decrease in the amplitude of oscillation over time due to energy loss, often from friction or resistance in the medium.
    • The maximum displacement of a particle from its equilibrium position in SHM is known as the amplitude.
    • When a ball is placed in a bowl and disturbed from its equilibrium position, it will exhibit oscillatory motion about the equilibrium position.
    • If the acceleration due to gravity (g) is increased, the time period of a simple pendulum decreases, resulting in a faster oscillation.
