Question 1
Oscillatory motion is best described as:
- AA to and fro motion about a mean position that repeats after equal intervals of time
- BMotion with constant velocity in a straight line
- CMotion with constantly increasing speed
- DMotion in a straight line that never repeats
Show answerHide answer
Answer: A
Oscillatory motion is a periodic to and fro motion about the mean position.
Question 2
Which of the following is NOT an example of oscillatory motion?
- AA vibrating tuning fork
- BA simple pendulum
- CA mass oscillating on a spring
- DA stone falling freely from rest
Show answerHide answer
Answer: D
A freely falling stone moves in one direction and does not repeat its motion.
Question 3
Every vibrating body has a position called the:
- AExtreme position
- BEquilibrium (mean) position
- CMaximum position
- DCritical position
Show answerHide answer
Answer: B
All vibrating bodies have an equilibrium or mean position about which they oscillate.
Question 4
One complete round trip of a vibrating body about its mean position is called a:
- ADisplacement
- BAmplitude
- CPhase
- DVibration (cycle)
Show answerHide answer
Answer: D
One vibration is a complete cycle such as the bob moving from A to B and back to A.
Question 5
The distance of a vibrating body from its mean position at any instant is called:
- AInstantaneous displacement
- BAmplitude
- CTime period
- DFrequency
Show answerHide answer
Answer: A
Instantaneous displacement x is the distance from the mean position at a given instant.
