Harmonic Oscillator: Understanding Period and Amplitude

What is the relationship between period, mass, force constant, and amplitude in a harmonic oscillator?

Given a harmonic oscillator with a period of 0.149 s and a maximum speed of 2 m/s, how can we determine the amplitude of the oscillation?

Relationship Between Period, Mass, Force Constant, and Amplitude

In a harmonic oscillator, the period (T) is related to the mass (m) and force constant (k) of the system through the equation: T = 2π√(m/k).

Finding the Amplitude

To find the amplitude of the oscillation, we need to calculate the force constant (k) using the given period and mass. Once we have the force constant, we can determine the amplitude using the maximum speed and angular frequency.

A harmonic oscillator exhibits periodic motion characterized by a specific period, amplitude, and maximum speed. The period of the oscillator is directly related to the mass of the block and the force constant of the spring that determines its behavior.

By using the formula T = 2π√(m/k), where T is the period, m is the mass, and k is the force constant, we can establish a connection between these fundamental parameters.

With the period given as 0.149 s and the mass as 0.690 kg, we can calculate the force constant (k) by rearranging the formula as k = 4π^2m/T^2.

Once we have determined the force constant, we can then proceed to find the amplitude of the oscillation using the formula X = vmax/ω, where vmax is the maximum speed and ω is the angular frequency calculated as ω = √(k/m).

Understanding the relationship between these variables is essential in analyzing the behavior of harmonic oscillators and predicting their movements based on given parameters.
