Study Notes
Simple Harmonic Motion
- The acceleration of a particle executing simple harmonic motion is directly proportional to its displacement from the mean position. This means that the greater the displacement, the greater the acceleration.
- Acceleration is zero at the mean position and reaches its maximum value at the extreme position, where the displacement is the maximum.
- At the extreme position, the acceleration attains the maximum value a2, known as the acceleration amplitude.
Acceleration-Time Graph
- The acceleration-time graph for simple harmonic motion is a negative sine curve.
- The acceleration is zero when the displacement is zero, meaning at the mean position, and maximum when the displacement is maximum, meaning at the extreme positions.
Exponential Function
- The exponential function is defined by the series expansion: eix = cos x + i sin x
- The exponential function is used to understand the behavior of oscillating systems, particularly damped oscillators.
Damped Simple Harmonic Motion
- In a damped simple harmonic oscillator, the amplitude of the oscillations decreases with time due to the loss of energy caused by resistive or frictional forces.
- The damping force is assumed to be proportional to the velocity of the oscillating system.
- The displacement in a damped simple harmonic oscillator is described by the equation: x = Ae-rt/2m sin (`t + )
Forced Oscillations
- At low frequencies ( → 0), the displacement amplitude of a forced oscillator is independent of frequency.
- At velocity resonance ( = 0), the velocity amplitude of a forced oscillator is independent of frequency.
- At high frequencies, the acceleration amplitude of a forced oscillator is independent of frequency
Wave Equation and Wave Velocity
- The wave equation describes the motion of waves and can be used to determine their velocity.
- The velocity of transverse waves moving along a string is determined by the tension (T) and the mass per unit length (m) of the string: c = √(T/m).
- The frequency (n) and wavelength () of a wave are related to its velocity by the equation: c = n.
Solutions to The Wave Equation
- y = f1(ct − x) and y = f2(ct+x) both represent solutions to the wave equation.
- These solutions indicate that the shape of a wave can be described as a function of two variables, x and t.
