1. One complete round trip of a body about a mean position is called: a) One vibration b) Time period c) Frequency d) Rotation

2. The maximum displacement of a vibration body from its equilibrium position is called: a) Amplitude b) Radius c) Distance d) Vibration

3. In simple harmonic motion the acceleration of a body is always directed towards and proportional to its displacement from: a) It's mean position b) It's extreme position c) The point at which force is applied d) None of these

4. According to Hook's Law the change in the length due to a hanging body with an elastic spring is directly proportional to: a) It's weight b) It's temperature c) It's velocity d) It's velocity

5. Kinetic energy of a mass attached with an elastic spring is maximum at: a) Mean position b) Extreme position c) Between mean and extreme positions d) None of these
