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 |
(A) | parabolic path |
(B) | elliptical path |
(C) | periodic motion |
(D) | simple harmonic motion |
1. | (B), (C), and (D) only |
2. | (A), (B), and (C) only |
3. | (A), (C), and (D) only |
4. | (C) and (D) only |
