Basic Concepts of Simple Harmonic Motion (SHM)
Simple Harmonic Motion (SHM) is a periodic motion where an object oscillates back and forth around a central point. It is characterized by a sinusoidal displacement function that repeats itself at regular intervals.
Mathematically, SHM is represented by the equation: x(t) = Acos(ωt + φ), where x(t) is the displacement at time t, A is the amplitude, ω is the angular frequency, and φ is the phase angle.
Examples of SHM in real-world applications include the motion of a pendulum, the vibration of a guitar string, and the oscillations of a spring-mass system.
Position-versus-Time Graph for SHM: Shows A Position-versus-time Graph For A Particle In Shm
A position-versus-time graph for SHM is a plot of the object’s displacement from the equilibrium position over time. The graph is a sinusoidal curve that repeats itself at regular intervals.
The shape of the graph is determined by the amplitude, period, and frequency of the motion. The amplitude is the maximum displacement from the equilibrium position, the period is the time it takes for one complete oscillation, and the frequency is the number of oscillations per unit time.
Key Features of the Position-versus-Time Graph
- Amplitude:The maximum displacement from the equilibrium position.
- Period:The time it takes for one complete oscillation.
- Frequency:The number of oscillations per unit time.
These features are related to the particle’s motion and energy. The amplitude is proportional to the maximum kinetic energy of the particle, the period is inversely proportional to the frequency, and the frequency is proportional to the square root of the spring constant.
