Identify the correct definition:
| 1. | If after every certain interval of time, a particle repeats its motion, then the motion is called periodic motion. |
| 2. | To and fro motion of a particle is called oscillatory motion. |
| 3. | Oscillatory motion described in terms of single sine and cosine functions is called simple harmonic motion. |
| 4. | All of the above |
| 1. | \(e^{\omega t}\) | 2. | \(\text{log}_e(\omega t)\) |
| 3. | \(\text{sin}\omega t+ \text{cos}\omega t\) | 4. | \(e^{-\omega t}\) |
The rotation of the earth about its axis is:
| 1. | periodic motion |
| 2. | simple harmonic motion |
| 3. | periodic and simple harmonic motion |
| 4. | non-periodic motion |
The circular motion of a particle with constant speed is:
| 1. | Periodic and simple harmonic | 2. | Simple harmonic but not periodic |
| 3. | Neither periodic nor simple harmonic | 4. | Periodic but not simple harmonic |
Which one of the following is not an example of simple harmonic motion?
| 1. | the motion of the Moon around the Earth as observed from Mars. |
| 2. | the ripples produced when a stone is dropped into a tank of water. |
| 3. | a weight moving up and down at the end of a spring. |
| 4. | the motion of a ball on the floor. |
