Question 1
1 / -0

If two bodies do not interact

A
still a force can be applied

B
no force can be applied

C
contact force can be applied

D
non-contact force can be applied

Solution

If two bodies do not interact there won't be any force between them as
interaction is must for having any sort of force between two bodies.
Question 2
1 / -0

When a football is kicked, its shape changes for a fraction of a second. This is because

A
force changes the shape of an object

B
force does not change the shape of an object

C
momentum changes the shape of an object

D
motion changes the shape of an object

Solution

Football is deformable body When a football is kicked, a contact force is applied and thus its shape changes. Hence Force is responsible to change its shape.
Question 3
1 / -0

You are pushing a ball. If your younger sister pushes it from the opposite side with lesser force, the ball will

A
move slower

B
move faster

C
move at same speed

D
move in another direction

Solution

When forces are applied from opposite directions, the forces get subtracted. So, the resultant or net force is less than the force which was applied initially. As a result, the object's speed will reduce.
Here, if you are pushing the ball with force $$F_1$$, and your sister is pushing it with force $$F_2$$ then the net force will be
$$F_{net}=F_1-F_2$$
Since $$F_1>F_2$$, then the net force $$F_{net}$$ is obviously less than $$F_1$$ which you were applying., and hence the ball moves slower.
Question 4
1 / -0

You alone can push a roller. But when your friend joins you, the roller moves faster. This is because:

A
forces in same direction add up.

B
forces in same direction do not add up.

C
forces in same direction get subtracted.

D
forces in same direction remain same.

Solution

When your friend joins you, both of you push the roller in same direction. So, your forces, being applied in same direction, add up to a larger value. Thus the roller moves faster.
Question 5
1 / -0

To pull a heavy goods' train, two engines are often connected one after another. This is to

A
increase the pull

B
decrease the pull

C
save the power

D
do none of these

Solution

Since both engines will try to pull in the same direction so their pull forces will add up and total pull on the train will increase which will make it easier to pull it.
Question 6
1 / -0

A spring is compressed when a force is applied. This is an example of

A
force changing the shape of an object

B
force changing the motion of an object

C
force breaking a rigid object

D
none of these

Solution

A spring gets compressed by the application of a force. This is an example of one of the effects of force: that it can change the shape of an object.
Question 7
1 / -0

Mechanical force exerted by living animals is

A
muscular force

B
magnetic force

C
electrostatic force

D
none of these

Solution

Mechanical force exerted by muscles of living animals is muscular force.
Question 8
1 / -0

If a force changes the shape of a body, the body should be

A
non-rigid

B
rigid

C
fluid only

D
none of these

Solution

An object that is easily folded on application of force and has a lot of flexibility is called a non-rigid body.
When a force is applied on a non-rigid body, its shape changes.
Question 9
1 / -0

When a force is applied on a non-rigid object,

A
its shape changes

B
its shape remains same

C
only its state of motion changes

D
nothing happens

Solution

A non-rigid body can not hold its shape when a force acts on it. It deforms under the action of the force. So, force can change the shape of a non-rigid body.
Question 10
1 / -0

When a force is applied on a rigid object

A
It changes the inter spacing between its constituent particles.

B
It changes the dimension of the object

C
It only causes motion in it

D
All

Solution

A force, when applied to a rigid object, does not change the interspacing between its constituent particles and therefore it does not change the dimension of the object. It only causes motion in it.
