  4. none of the above

Show answer
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?

physics kinematics different types of motion basics of motion motion and reference point

  1. Motion

  2. Rest

  3. Stationary

  4. None of the above

Show answer
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?

physics kinematics different types of motion basics of motion motion and reference point

  1. Rectilinear motion

  2. Periodic motion

  3. Circular motion

  4. None of the above

Show answer
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.

physics kinematics different types of motion basics of motion motion and reference point

  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

Show answer
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 as 
physics along with motion different types of motion basics of motion motion and reference point

  1. Rolling

  2. Rotatory

  3. Both A and B

  4. Translational

Show answer
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?

physics along with motion different types of motion basics of motion motion and reference point

  1. Periodic motion

  2. Rectilinear motion

  3. Circular motion

  4. None of the above

Show answer
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.

If an object moves along a straight path it is said to be ____ or ____ motion. Fill in the blank.

physics along with motion different types of motion basics of motion motion and reference point

  1. Linear

  2. one dimensional

  3. two dimensional

  4. both A and B

Show answer
Correct Option: D
Explanation:

Linear motion (also called rectilinear motion) is one dimensional motion along straight line.

Which of the following is a type of motion?

physics along with motion different types of motion basics of motion motion and reference point

  1. Circular

  2. Rectilinear

  3. Periodic

  4. All of the above

Show answer
Correct Option: D
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

physics motion and types of motion different types of motion basics of motion motion and reference point

  1. Uniform

  2. Accelerated

  3. Retarded

  4. Along a circular track

Show answer
Correct Option: B
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 :

physics motion and types of motion different types of motion basics of motion motion and reference point

  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.

Show answer
Correct Option: A,B
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.
