Introduction:
The quality factor, also known as Q-factor, is a measure of the sharpness or quality of a resonant system. It is commonly used to describe the behavior of oscillating systems, such as pendulums. In this scenario, we have a simple pendulum that undergoes a decrease in amplitude over a certain period of time. We are asked to determine the quality factor of the pendulum based on the given information.
Given Information:
- Period of the pendulum = 1 second
- Initial amplitude = 100
- Final amplitude after 10 oscillations = 50
Calculating the Quality Factor:
The quality factor of a pendulum can be determined using the formula:
Q = (2π × Initial Amplitude) / (Final Amplitude)
Step 1: Convert the period to frequency
The period of the pendulum is given as 1 second. The frequency (f) can be determined by taking the reciprocal of the period: f = 1 / T
Step 2: Calculate the angular frequency
The angular frequency (ω) can be determined using the formula: ω = 2πf
Step 3: Determine the decay constant
The decay constant (λ) can be calculated using the formula: λ = (1 / 10) × (ln(A0 / A))
where A0 is the initial amplitude and A is the final amplitude.
Step 4: Calculate the quality factor
Finally, the quality factor (Q) can be calculated using the formula: Q = ω / (2λ)
Conclusion:
By plugging the given values into the formulas and performing the calculations, it is determined that the quality factor of the simple pendulum is approximately 45.33. This value indicates that the pendulum has a relatively sharp resonance and a high level of damping.
