Question 1
1 / -0

When a spring is pulled:

A
Shape of the spring changes

B
Size of the spring changes

C
Size of the spring doesn't change

D
Both $$A$$ and $$B$$

Solution

Force is an external agent (push or pull) which changes the state of motion or rest of an object.
When spring is pulled, both the shape and size of the spring change.
Question 2
1 / -0

What type of force is applied in kicking a football?

A
Magnetic force

B
Muscular force

C
Electrical force

D
Nuclear force

Solution

A football is kicked with the help of foot muscles. So, the force applied is mechanical force.
Question 3
1 / -0

Mark the correct option

A
Force can be seen

B
When an inflated balloon is pressed between the two hands,only its shape changes

C
Force is a push,pull or squeeze

D
All

Solution

Force cannot be seen.we can 'see' or 'feel' the force through its effects.when an inflated balloon is pressed between the two hands,its shape and size changes.

Force acting on a body is a push,pull or a squeeze.
Question 4
1 / -0

Muscular force is a type of

A
mechanical force

B
magnetic force

C
electrostatic force

D
gravitational force

Solution

Muscular force is a type of mechanical force as it is produced by mechanical contraction of muscles.
Question 5
1 / -0

Muscular force can:

A
Change the state of motion of an object

B
Change the shape of an object

C
Both $$A$$ and $$B$$

D
None of these
Question 6
1 / -0

What type of force is applied to pick up a load from ground by hand?

A
Muscular force

B
Magnetic force

C
Electrostatic force

D
Gravitational force

Solution

We pick up loads from the ground with our hands with the help of our muscles. So, the type of force applied is muscular force.
Question 7
1 / -0

Force is _______. Fill in the blank.

A
a push

B
a pull

C
both A and B

D
none of these

Solution

Force is a push or pull which changes or tends to change the state of rest or of uniform motion.
Question 8
1 / -0

Mark the incorrect option:

A
A force always make an object to move

B
A force has both magnitude and direction

C
A force can be represented by an arrow

D
Force is a vector quantity

Solution

We are to remember that force does not always make an object to move. For example,we may push a large piece of rock without displacing it from its position.We may even push a wall without any success. And, on the other had, we may apply force on a dough by our fingers to change its shape and size. So, a force does not always make an object to move, it may be used to change the shape and size of an object as well.

Force is a vector quantity because it has both magnitude and direction.
It can be represented by an arrow.
Question 9
1 / -0

Fill in the blank.
When a force is applied on a soft object,it changes the_________ of the object.

A
Shape

B
Size

C
Direction of force

D
Both a and b

Solution

A soft object is a non-rigid object. Force can change the shape and size of a soft object.
Question 10
1 / -0

A force when applied on a non rigid object

A
it does not change the inter spacing between its constituent particles

B
it does not cause any change in its dimension

C
it does not produce motion in it

D
None

Solution

A force when applied to a non-rigid object, the object can not hold its original shape. Therefore, the inter-spacing between the constituent particles changes. At the same time, the force causes a change in the state of motion of the object. So, none of the given options is correct.
