os.motion

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

• transitional motion.

• b. oscillatory motion.

• wave motion

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

• decreases تقل when it goes far from بعيد عن its rest position.

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

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

Kinetic energy =

• 1/2 MV²

• M²V²

• M

• V

All of the following are examples of oscillatory motion, except

• motion of a simple pendulum.

• motion of a car.

• motion of a tuning fork.

• motion of a string.

The oscillaloty motion is regularly repealed through equal intervals of time.

• 
• 

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

• 
• 

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

its rest position,

• true

• false

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

• true

• false

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

• true

• false

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

• true
