What is the phase difference between displacement and acceleration in Simple Harmonic Motion?
Answer and explanation
Correct answer: C. pi radians
- Step 1: In SHM, acceleration is a = -omega^2 x = omega^2 A sin(omega t + pi). Step 2. Therefore, acceleration is always opposite in direction to displacement, with a phase difference of pi radians (180 degrees). Answer: pi radians. Why not the others: pi / 2 is between displacement and velocity; 0 radians would mean same direction; 3 pi / 2 is 270 degrees.
