Concepts Of Physics MCQ Edition [Volume 1]PhysicsSimple Harmonic Motion
For a particle undergoing simple harmonic motion, the displacement over one time period is
Options
- AA
- B4A
- C2A
- Dzero
Correct answer
D. zero
Step-by-step solution
The displacement of a particle in simple harmonic motion is given by x(t) = A ( t + ) . After one complete time period T = 2 , the position of the particle is: x(t+T) = A ( (t+T) + ) x(t+T) = A ( t + 2 + ) = A ( t + ) = x(t) Since the initial and final positions of the particle are the same after one time period, the net displacement is zero. The total distance traveled over one time period is 4A , but the displacement is zero.
