Weekly Quiz Competition

Question 1
1 / -0

Which of the following actions describe pushing force?

A
Kicking

B
Lifting

C
Picking

D
Opening

Solution

Kicking is a pushing action while the others are pulling actions.
Question 2
1 / -0

Which of the following is NOT a force?

A
Muscular

B
Magnetic

C
Chemical

D
Electric

Solution

Chemical energy is not a force.
Question 3
1 / -0

A force is applied on an object in the direction of its motion. What is the effect of force on the object?

A
The speed of the object will increase.

B
The speed of the object will decrease.

C
The speed of the object will remain unchanged.

D
The object comes to rest.

Solution

Since, the force is applied in the direction of motion of the object, the speed of the object will increase.
Question 4
1 / -0

If no force acts on a body at rest, then what effect can be observed?

A
The body changes shape.

B
The body moves with increased speed.

C
The body remains at rest.

D
The body breaks up.

Solution

In the absence of a force, a body will remain at rest (static object) or move with uniform velocity.
Question 5
1 / -0

Which of the following examples describe the change of shape on applying force?

A
A ball being kicked

B
A fan switched on

C
A man jumping from a height

D
Repeatedly tearing of a paper

Solution

We apply certain force to tear a paper. The shape of the paper changes after it is repeatedly torn into pieces.
Question 6
1 / -0

Which of the following effects is caused by frictional force?

A
Change in the shape of an object

B
Change in the direction of the motion of an object

C
Slowing down of a moving object

D
Acceleration in a moving body

Solution

Frictional force between two surfaces tends to decrease the speed of a moving object.
Question 7
1 / -0

Which of the following is a non-contact force?

A
Muscular force

B
Electrostatic force

C
Elastic spring force

D
Frictional force

Solution

The electrostatic force is a non-contact force.
Question 8
1 / -0

What causes the atmospheric pressure?

A
The sky above our head

B
The air surrounding the earth

C
The gravitational force of the sun and other planets

D
The mass of the earth

Solution

Atmospheric pressure is caused by the weight of air molecules surrounding the earth.
Question 9
1 / -0

How does the pressure exerted by a liquid change?

A
Increases with depth

B
Decreases with depth

C
Remains constant

D
First increases and then decreases

Solution

The pressure exerted by a liquid increases with depth.
Question 10
1 / -0

What is thrust equal to?

A
Force×area

B
Force/area

C
Pressure

D
  Pressure×area

Solution

Thrust is the total force applied on a given area. It is given as the product of pressure and area.
