What is the term for the maximum displacement from the position at rest?

• A. Damping
• B. Amplitude
• C. Frequency
• D. Velocity

Answer: (B)

Amplitude is the maximum displacement from the rest position. In oscillatory systems like a mass on a spring or a swinging pendulum, it represents how far the object moves from equilibrium at its furthest point. This size of motion stays constant in ideal simple harmonic motion, though damping can cause the amplitude to decrease over time. The velocity is the instantaneous speed and direction of motion, and it becomes zero at the maximum displacement when the object turns around. Frequency, on the other hand, tells you how many complete oscillations occur per unit time, not how far the system moves. Damping refers to mechanisms that reduce the amplitude over time.
