Questions Related to motion around us

A ball lying on the ground does not move on its own because:

physics kinematics motion around us motion and rest moving things around us

  1. it has inertia

  2. it has no energy

  3. it does not want to move

  4. All of the above

Show answer
Correct Option: A
Explanation:

According to Newtons's first law , body remains in its state unless acted by external force. This property of body is termed as Inertia.

Option A is correct.

A tree in a park is in a state of _____with respect to the ground.

physics kinematics motion around us motion and rest moving things around us

  1. rest

  2. motion

  3. data is insufficient

  4. both A and B

Show answer
Correct Option: A
Explanation:

This totally depends on the frame of refrence, any object is relatively at rest or moving.

earth as  frame of refrenece in this case, the tree is at rest.

The earth is in a state of ______

physics kinematics motion around us motion and rest moving things around us

  1. motion

  2. rest

  3. both a and b

  4. linear motion

Show answer
Correct Option: A
Explanation:

Earth is continously moving in its orbit around the sun and on its own axis.

So, it is in the state of motion.

A book lying on a table is an example of -

physics kinematics motion around us motion and rest moving things around us

  1. a body in motion

  2. a body at rest

  3. a body neither at rest nor in motion

  4. none of these

Show answer
Correct Option: B
Explanation:

when the position of a body does not change with respect to its surroundings and time the body is said to be in rest. A book lying on the table is at rest because its position with respect to other object on table or room is fix. 

A book lying on a table is in a state of ____

physics kinematics motion around us motion and rest moving things around us

  1. rest

  2. motion

  3. periodic motion

  4. linear motion

Show answer
Correct Option: A
Explanation:

A book lying on the table is at rest. 


Since no net external force is acting on the book in this state and so it is not capable of moving the book.

Option A is correct.

Electric drill, rolling ball, wheel of a moving car, pendulum of a wall clock,spinning ball. Find the odd one out.

physics kinematics motion around us motion and rest moving things around us

  1. pendulum of a wall clock

  2. Electric drill

  3. wheel of a moving car

  4. spinning ball

Show answer
Correct Option: A
Explanation:

Pendulum of a wall clock- It is in periodic motion. Rest all are in multiple motion. The restoring force is proportional to displacement .While electric drill, rolling ball etc are in multiple motion like rotational +transnational or Vibrational motion.

Apple falling from a tree, car moving on a straight road, coins moving over a carrom board, giant wheel. Find the odd one out:

physics kinematics motion around us motion and rest moving things around us

  1. gaint wheel

  2. Apple falling from a tree

  3.  car moving on a straight road

  4. coins moving over a carrom board

Show answer
Correct Option: A
Explanation:

Giant wheel- because it has rotational motion as well as transnational motion. While apple falling from a tree, a car moving on straight rod and coin moving over a carrom board have only linear or rectilinear motion.  

Find the odd one out.
Table, chair, tree, moon

physics kinematics motion around us motion and rest moving things around us

  1. moon

  2. chair 

  3. tree

  4. table

Show answer
Correct Option: A
Explanation:

Moon 

When the position of a body does not change with respect its surroundings and time the body is said to be in rest.
But moon is in motion with respect to earth while other object like book ,table and tree are in rest with respect to earth . When these object are viewed from other planet ,then they will appear moving with earth velocity.  

Tree, hut, earth, dustbin, chair. Find the odd one out.

physics kinematics motion around us motion and rest moving things around us

  1. earth

  2. Tree

  3. dustbin

  4. chair

Show answer
Correct Option: A
Explanation:

Earth, because earth is in motion while other object are in rest with respect to earth.  

Select the odd one :

Bouncing ball, spinning top, oscillating pendulum, study table

physics kinematics motion around us motion and rest moving things around us

  1. study table

  2. bouncing ball

  3. spinning top

  4. oscillating pendulum

Show answer
Correct Option: A
Explanation:

All the three object are in any osscilatory motion wrt to earth as frame of refrence. But study table is at rest.

So study table is odd one out of the four objects.
