1. What is Amplitude of Motion?

The amplitude of motion (A) is the maximum displacement from equilibrium position in periodic motion. It represents the furthest point the object moves from its rest position during oscillation.

2. How Does the Calculator Work?

The calculator uses the simple equation:

Where:

• \( A \) — Amplitude of motion (m)
• \( x_{max} \) — Maximum displacement from equilibrium (m)

Explanation: For simple harmonic motion, the amplitude is simply the maximum displacement value.

3. Importance of Amplitude Calculation

Details: Amplitude is crucial in oscillatory systems as it determines the energy of the system and affects frequency in some cases. It's used in engineering, physics, and various wave applications.

4. Using the Calculator

Tips: Enter the maximum displacement value in meters. The value must be positive.

5. Frequently Asked Questions (FAQ)

Q1: Is amplitude the same as maximum velocity?
A: No, amplitude is maximum displacement. Maximum velocity occurs when passing through equilibrium position.

Q2: Can amplitude be negative?
A: While displacement can be negative, amplitude as a measure of maximum displacement is always positive.

Q3: How does amplitude relate to energy?
A: In simple harmonic motion, total energy is proportional to the square of the amplitude.

Q4: What's the difference between amplitude and wavelength?
A: Amplitude is maximum displacement, while wavelength is the distance between successive identical points in a wave.

Q5: Does amplitude affect period in simple harmonic motion?
A: For ideal simple harmonic motion, period is independent of amplitude (isochronous motion).
