The oscillatory motion is regularly repeated through equal intervals of time.

• false

• true

The amplitude is measured in a metre.

• false

• true

The simple harmonic motion is a form of the oscillatory motion.

• false

• true

The velocity of the oscillating body reaches its maximum value when it passes

its rest position.

• false

• true

The kinetic energy of the simple pendulum decreases by increasing its velocity.

• false

• true

The oscillation of the tuning fork is an example of the periodic motion.

• false

• true

The motion of a swing is an example of periodic motion.

• false

• true

The movement of a swing is known a ****

• b. oscillatory motion.

• a. transitional motion.

• d.circular motion.

• c.wave motion.

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

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

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

• C. will reach its minimum value when it passes its rest position.

• d. remains constant.
