Sample questions from this chapter

What defines periodic motion?
  1. Motion that repeats after equal time intervals ✓
  2. Motion that always follows a straight line
  3. Motion with constant velocity only
  4. Motion that never returns to a previous state
Answer: A. Periodic motion reproduces its state after a fixed least interval called the period.
Why not B: A periodic trajectory may be curved, rotational or oscillatory.
Why not C: Constant-velocity motion on an unbounded line does not repeat its state.
Why not D: Failure to recur is the opposite of periodic behaviour.
An oscillator makes 120 complete cycles per minute. What is its frequency?
  1. 120 Hz
  2. 0.500 Hz
  3. 2.00 Hz ✓
  4. 60.0 Hz
Answer: C. ν=120/60=2.00 cycles per second or 2.00 Hz.
Why not A: This treats one minute as one second.
Why not B: This divides 60 by 120, calculating the period in seconds instead.
Why not D: This divides the cycle count by two rather than by 60 seconds.
A 1.00 kg mass oscillates on a 100 N m⁻¹ spring. What is its period?
  1. 0.628 s ✓
  2. 0.100 s
  3. 6.28 s
  4. 10.0 s
Answer: A. T=2π√(1.00/100)=2π(0.100)=0.628 s.
Why not B: This uses √(m/k) but omits the factor 2π.
Why not C: This takes √(k/m)=10 as though its reciprocal were one second.
Why not D: This reports angular frequency 10 rad s⁻¹ as a time.
