Oscillations

2. Type of oscillatory system in which a force is repeatedly applied to keep it oscillating.
4. One complete to-and-fro motion.
5. Applying a restraining force to an oscillating system to reduce its amplitude of oscillations.
6. This is the frequency at which a system oscillates in the absence of driving or damping forces.
8. An oscillator that in not under the influence of external forces.
11. In simple harmonic motion, the acceleration is always in a direction opposite to this quantity.
12. Type of periodic motion that is characterized by a regular to-and-fro motion.
13. When a system is resonating, this quantity is at a maximum.

1. The time required for one complete oscillation.
3. The phenomenon that occurs when a periodic force drives an oscillator at its natural frequency.
7. This is the number of complete oscillations per unit time.
9. In this type of damping, the system returns to its equilibrium position in the shortest possible time.
10. If you pluck a guitar string and then touch it with your hand, the sound dies out because the guitar string’s motion is
