Question 1
1 / -0

The force resulting due to the action of muscles is known as the ____________.

A
Muscular force

B
Electromagnetic force

C
Nuclear force

D
None of the above

Solution

When we push an object like a school bag or lift a bucket of water. This force is caused by the action of muscles in our body. The force resulting due to the action of muscles is known as the muscular force.
Question 2
1 / -0

When a charged balloon attaches to wall without any help ___________ force is in action.

A
Magnetic Force

B
Electrostatic Force

C
Muscular Force

D
Force of Gravity

Solution

The force exerted by a charged body on another charged or uncharged body is known as electrostatic force. This force comes into play even when the bodies are not in contact. The electrostatic force, therefore, is another example of a non-contact force.

When a charged balloon attaches to wall without any help electrostatic force is in action.
Question 3
1 / -0

A force that oppose the motion of one surface sliding over other is called;

A
Gravitational Force

B
Friction

C
Push and pull

D
Electrostatic force.

Solution

The force of friction opposes the motion of one surface sliding over the other. Friction opposes the motion. Hence option B is the correct answer.
Question 4
1 / -0

The SI unit of force is;

A
Newton

B
Watt

C
Joule

D
Coulomb

Solution

The SI I unit of force is Newton. That is denoted by N symbol.
Question 5
1 / -0

There is one force which is exerted by all matter on all other matter. What force is this?

A
Gravitational force

B
Magnetic force

C
Electromagnetic force

D
Frictional force

Solution

Objects or things fall towards the earth because it pulls them. This force is called the force of gravity, or just gravity. In fact, every object in the universe, whether small or large, exerts a force on every other object. This force is known as the gravitational force.

Thus option A is the correct answer.
Question 6
1 / -0

What is a force?

A
Push

B
Pull

C
Both push and pull

D
None of these

Solution

In science, a push or a pull on an object is called a force. Thus, we can say that the motion imparted to objects was due to the action of a force.

Hence option C is the correct answer.
Question 7
1 / -0

Force can affect the state of motion of a body by:

A
Increasing speed

B
Changing shape of the object

C
Changing direction of speed

D
Both increasing speed and Changing direction of speed

Solution

A change in either the speed of an object, or its direction of motion, or both, is described as a change in its state of motion. Thus, a force may bring a change in the state of motion of an object.

Thus option D is the correct answer.
Question 8
1 / -0

Is force always accompanied by change in shape of object?

A
No

B
Yes

C
Never

D
Sometimes

Solution

Force may bring change in the shape of an object. Although it might not always affect the change in the shape of the object. The change in the shape of the object may occur if the force acting on the object is of greater magnitude. Thus option D is the correct answer.
Question 9
1 / -0

Force exerted during digestion of food in elementary canal is:

A
Force of Friction

B
Force of gravity

C
Magnetic Force

D
Muscular Force

Solution

The digestion of food is caused by the action of muscles in our body. The force resulting due to the action of muscles is known as the muscular force.

Therefore, option D is the correct answer.
Question 10
1 / -0

Which of the following statement incorrectly describe the characteristics of force;

A
it may make an object move from rest

B
may change the direction of motion of an object.

C
always bring about a change in the shape of an object

D
may change the speed of an object if it is moving

Solution

Force may bring change in the shape of an object. Although it might not always affect the change in the shape of the object. The change in the shape of the object may occur if the force acting on the object is of greater magnitude.

Apart from this a force may bring some or all of these affect mentioned in the options.

Hence option C is the correct answer.
