Question
The phase (at a time t) of a particle in simple harmonic motion tells:
- Neither the position of the particle nor its direction of motion at time t
- Both the position and direction of motion of the particle at time t
- Only the direction of motion of the particle at time t
- Only the position of the particle at time t
Hint:
The phase (at a time t) of a particle in SHM is a physical quantity that wholly expresses the position and direction of motion of that particle of time t
The correct answer is: Both the position and direction of motion of the particle at time t
In simple harmonic motion, the phase at a time t of a particle expresses the position and direction both of that particle
