  1. True

  2. False


Correct Option: A
Explanation:

The given statement is true that the motion of an ant on the floor along the edges is an example of translatory motion.

Smoke particles from a chimney exhibit :

  1. Random or irregular motion

  2. Circular motion only

  3. Linear motion only

  4. Rotational motion only


Correct Option: A
Explanation:

Smoke particles from the chimney have velocities in different direction and thus they exhibit random or irregular motion.

Name the type : A flying insect

  1. Random motion (Irregular motion)

  2. Circular motion

  3. Rolling motion

  4. Purely translation motionĀ 


Correct Option: A
Explanation:

A flying insect is an example of random motion (irregular motion).

Rectilinear motion is a motion that occurs in :

  1. Straight line

  2. Plane

  3. Both A and B

  4. None


Correct Option: A
Explanation:

The rectilinear motion is a straight line motion or one dimensional motion.

The process of change in position of an object over time is called

  1. rest

  2. stationary

  3. motion

  4. none of the above


Correct Option: C
Explanation:

A body is said to be in motion if it changes its position over time.

What we say when a body remains in one position for a long time?

  1. Motion

  2. Rest

  3. Stationary

  4. None of the above


Correct Option: B
Explanation:

A body is said to be at rest if it remains in one position for a long time.

Which type of motion of an object that moves in a straight line?

  1. Rectilinear motion

  2. Periodic motion

  3. Circular motion

  4. None of the above


Correct Option: A
Explanation:
Rectilinear motion is an another name for straight line motion.
Ex. A train moving on a track.

What is common to the following?
Motion of the propeller of a flying helicopter, the minute hand of a watch, the tape of cassette recorder.

  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


Correct Option: C
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.

The motion in which all points of a moving body move uniformly in the same line or direction is known asĀ 
  1. Rolling

  2. Rotatory

  3. Both A and B

  4. Translational


Correct Option: D
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 type of motion of an object that moves at a fixed distance from a fixed point?

  1. Periodic motion

  2. Rectilinear motion

  3. Circular motion

  4. None of the above


Correct Option: C
Explanation:

Circular motion is the motion of an object that moves at a fixed distance from a fixed point. Here all objects rotate in circular motion.
