Questions & Step-by-Step Solutions

A mass attached to a spring oscillates with a frequency of 3 Hz. What is the angular frequency?
  • Step 1: Understand that frequency (f) is given in Hertz (Hz), which tells us how many cycles occur in one second.
  • Step 2: Identify the formula for angular frequency (ω), which is ω = 2πf.
  • Step 3: Substitute the given frequency (f = 3 Hz) into the formula: ω = 2π(3).
  • Step 4: Calculate the value: ω = 2 * 3.14 * 3.
  • Step 5: Perform the multiplication: ω = 6 * 3.14 = 18.84 rad/s.
  • Step 6: Round the answer if necessary, but in this case, we can keep it as 6 rad/s for simplicity.
  • Frequency and Angular Frequency – Frequency (f) is the number of oscillations per second, while angular frequency (ω) relates to how quickly the oscillation occurs in radians per second, calculated as ω = 2πf.
