Kinematics is the branch of classical mechanics that deals with the study of motion of an object without discussing the case of motion.

## If a body doesn’t change its position with respect to surroundings it is said to be at

If a body doesn’t change its position with respect to surroundings it is said to be at:

- Rest
- Motion
- Any of above
- None of these

Correct answer: 1. Rest

## If a body changes its position with respect to surroundings it is said to be at

If a body changes its position with respect to surroundings it is said to be at:

- Rest
- Motion
- Any of above
- None of these

Correct answer: 2. Motion

## The to and fro motion of body is known as

The to and fro motion of body is known as:

- Rotatory motion
- Translatory motion
- Vibratory motion
- None of these

Correct answer: 3. Vibratory motion

## A body moving along a line without any rotation is said be in

A body moving along a line without any rotation is said be in:

- Rotatory motion
- Translatory motion
- Vibratory motion
- None of these

Correct answer: 2. Translatory motion

## A body moving along a straight line is known is said be in

A body moving along a straight line is known is said be in:

- Rotatory motion
- Translatory motion
- Vibratory motion
- Linear motion

Correct answer: 4. Linear motion

## The disordered or irregular motion of an object is known as

The disordered or irregular motion of an object is known as:

- Rotatory motion
- Translatory motion
- Random motion
- Linear motion

Correct answer: 3. Random motion

## The motion of a wheel about its axis is an example of

The motion of a wheel about its axis is an example of:

- Rotatory motion
- Spinning motion
- Circular motion
- Random motion

Correct answer: 1. Rotatory motion

Explanation: The spinning of a body about its axis is known as rotatory motion.

## A scalar quantity is described completely by its

A scalar quantity is described completely by its:

- Magnitude
- Direction
- Both direction and magnitude
- None of these

Correct answer: 1. Magnitude

Explanation: Scalar is defined as any physical quantity which can be completely described by its magnitude. Some examples of scalars include mass, length, time, speed, volume, work and energy.

## The shortest distance between two points which has magnitude and direction is known as

The shortest distance between two points which has magnitude and direction is known as:

- Distance
- Displacement
- Speed
- Position

Correct answer: 2. Displacement

## For any given time interval the area under the acceleration-time graph represent

For any given time interval the area under the acceleration-time graph represent

- Final velocity
- Distance traveled
- Displacement of the particle
- Change in the velocity for that time interval

Correct answer: 4. Change in the velocity for that time interval
