A particle moving back and forth over the same path is undergoing:

  1. Circular motion
  2. Oscillatory (periodic) motion
  3. Uniform motion
  4. Linear motion
Show answer and solution

Correct answer: B. Oscillatory (periodic) motion

Oscillatory or vibratory motion is back-and-forth motion over the same path. **Examples:** pendulum, mass on spring, vibrating string.

A particle executing SHM has time period T. Time taken to go from extreme position (x = A) to x = A/2:

  1. T/4
  2. T/6
  3. T/8
  4. T/12
Show answer and solution

Correct answer: B. T/6

With x = A cos(ωt) starting at extreme: x = A/2 when cos(ωt) = 1/2, so ωt = π/3, hence t = T/(2π) × π/3 = T/6.

For SHM, the displacement-time graph is:

  1. Parabola
  2. Sinusoidal
  3. Hyperbola
  4. Straight line
Show answer and solution

Correct answer: B. Sinusoidal

x = A sin(ωt + φ) is a sinusoidal (sine wave) function. **So x-vs-t graph is a sine curve.**
