Question 1
1 / -0

Fill in the blank.
A rubber balloon _________ when the molecules of air exert force on its walls.

A
Expands

B
Contracts

C
No change in dimension is seen

D
All of the above

Solution

Force can bring change in dimension.A rubber balloon expands when the molecules of air exert force on its walls.
Question 2
1 / -0

When two forces,applied on an object, equal and opposite,then the forces

A
May move the object

B
May stop the object

C
May move the object and also cause a change in its shape

D
Do not move the object but may cause a change in its shape.

Solution

A force may not always succeed in bringing a change in the state of motion of an object.

When equal and opposite force is applied it do not let the body to move,but cause change in shape of the body.
Question 3
1 / -0

If two forces act in opposite directions on an object,the net force acting on it is the

A
Addition of two forces

B
Difference of two forces

C
Division of two forces

D
Multiplication of two forces

Solution

Forces applied on an object in the same direction add to one another.

If two forces axt in the opposite directions on an object,the net force acting on it is the difference between the two forces
Question 4
1 / -0

Mark the correct option

A
The state of motion of an object is described by its speed only

B
Many a time application of force does not result in a change in the state of motion of an object.

C
By sitting on a bicycle seat force is applied to the spring fixed to the seat of the bicycle

D
All of the above
Solution
The statement in option A is true. The object can be in a state of motion or rest which can be described using its speed. State of rest is just a state of motion with speed zero.
In option B, it is common experience that many a time application of force does not result in a change in the state of motion. For example, a heavy box may not move at all even if you apply the maximum force that you can exert.
The force applied on the spring fixed to the seat of the bicycle is an example of effect of force. The force changes the shape of the object (spring).

So all the three option are correct. Answer is option D.
Question 5
1 / -0

Change of shape and size due to force can be seen by applying force on:

A
a spring

B
a sponge

C
an inflated balloon by pressing between the two hands

D
all of these

Solution

When a force is applied on a soft object, the shape and size of the object can change. So, for spring, sponge, and inflated balloon, shape and size are changed by application of force.
Question 6
1 / -0

Length of a rubber band ________ when a stretching force is applied.

A
Increases

B
Decreases

C
Remains same

D
None

Solution

Force can bring change in dimension like in the case of the rubber band when a stretching force is applied, its length increases.
Question 7
1 / -0

If force is applied on the body in the direction of motion then

A
Speed of the body will increase

B
Speed of the body will decrease

C
Speed of the body will not change at all

D
All the options are possible

Solution

If applied force acts on a body in the direction of motion,the speed of the body will increase.

If the direction of force on the body is opposite to the direction of motion,the speed will decrease.
Question 8
1 / -0

In the game of cricket, the stumps fall when the ball strikes them. This is an example of

A
Contact force

B
Non contact force

C
Displacement force

D
None

Solution

The contact forces represent the result of physical contact between two objects, one by which force is exerted and the other by which force is exerted.
Question 9
1 / -0

Identify the type of force in diagram

A
Push

B
Pull

C
No force is acting

D
Both A and B

Solution

When a force is exerted in such a way that movement caused is towards oneself, such type of force is pull.
Question 10
1 / -0

Force can also be defined as

A
Mass per unit volume

B
Distance covered in unit time

C
External cause which can change the state of motion

D
None

Solution

Force is an external cause which can change the state of rest or motion of a body
