 1. Simple Harmonic Motion (SHM) is defined as an oscillation where ..

  • A. acceleration is proportional to the displacement from the centre.
  • B. acceleration is proportional to the speed of the oscillation.
  • C. acceleration is proportional to the velocity of the oscillation.
  • D. acceleration is proportional to the mass of the system.

 

2. The acceleration of the system is always..

  • A. directed to the left.
  • B. directed to the right.
  • C. in the opposite direction to the displacement from the centre.
