उत्तर
| Natural Vibration | Forced Vibration | |
| i. | An object's natural vibrations are its inherent vibrations, which occur at a consistent amplitude and frequency. |
Forced vibrations are those that occur as a result of being subjected to a periodic external force. |
| ii. | The amplitude changes with time. | Amplitude doesn't change throughout time. |
| iii. | The body's intrinsic frequency causes it to vibrate. | Does not move at its own natural frequency, but instead learns to deduce its own. |
