1. The movement of a swing is known as...........

• a. transitional motion.

• b. oscillatory motion.

• c. wave motion.

•  d. (a) and (b) together.

2. The oscillating body moves at the two sides of its rest position, so its velocity..........

• a. decreases when it goes far from its rest position.

• b. increases when it goes far from its rest position.

•  c. will reach its maximum value when it passes its rest position.

• d. (a) and (c) together.

3. Kinetic energy = ½ x………….

• m/v²

• m.v²

• m²v²

• m.v3

4. All of the following are examples of oscillatory motion except.....

• a. motion of string.

• b. motion of a tuning fork.

• c. motion of car

• d. motion of a simple pendulum.

The maximum displacement achieved by the oscillating body away from its rest position.................

• frequency

• periodic time.

• complete oscillation

• amplitude

If the periodic time of an oscillating body is 0.1 sec., so the number of complete

 

oscillations in one minute is......

• 10

• 600

• 120
