  1. All are example of translatory motion

  2. All are examples of oscillatory motion

  3. All are examples of rotatory motion

  4. All are examples of periodic motion
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Motions of the propeller of a flying helicopter, the minute hand of watch and tape of cassette recorder are the example of rotatory motion.
Correct answer is option C.

Multiple choice physics along with motion different types of motion basics of motion motion and reference point
The motion in which all points of a moving body move uniformly in the same line or direction is known as 

  1. Rolling

  2. Rotatory

  3. Both A and B

  4. Translational
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
If a body rotates its motion its rotatory. Rolling motion is combination of rotation and translation motion.
Only in translational motion body moves along a straight line, that means body doesn't rotate then its motion is translational.

Which of the following is a type of motion?

  1. Circular

  2. Rectilinear

  3. Periodic

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
'A body is said to be in motion, if it changes its position with respect to its surrounding.'
Example;-Circular motion;"The motion of an object in a circular path is known as circular motion"
Linear motion-"(also called rectilinear motion) is one dimensional motion along straight line"
Periodic motion-Motion repeated in equal intervals of time

If a coin is tossed by a boy in a moving train and it falls behind him, then the motion of the train is

  1. Uniform

  2. Accelerated

  3. Retarded

  4. Along a circular track
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

If the train was moving with uniform velocity, then the coil would have fallen at the same place from where it was tossed up. 

When the train is accelerating it changes its speed (increases),on the other hand the coin still moves with the same speed as before .So when the coin is tossed, by the time the coin reaches back, the train would have moved ahead and so the coin will fall behind the spot from where it was tossed.

A person, seated in a train under motion, is at rest with reference to :

  1. The train.

  2. A person watching him from the front seat.

  3. A car moving opposite to the train.

  4. Trees on the ground.

A,B Correct answer
Explanation

When a man seats in a train, he is rest with respect to the train and with respect to another train or car which is moving opposite with same velocity of the first train.
