Weekly Quiz Competition

Question 1
1 / -0

Inertia is __________.

A
A property of mass

B
A type of force

C
The speed of an object

D
None of these

Solution

The mass of an object is a measure of its inertia. Its SI unit is $$kilogram\ (kg)$$.
Question 2
1 / -0

Catching a cricket ball is an example of:

A
Balanced force

B
Unbalanced force

C
Both A and B

D
Neither A nor B

Solution

Catching a cricket ball, being an unbalanced force, causes the change in state of motion of the ball.
Question 3
1 / -0

In order to apply a force on the body:

A
there has to be an interaction.

B
there must be no interaction.

C
sometimes there may be an interaction.

D
None of these

Solution

Two bodies must interact in order to apply a force.
Whenever we see a force acting we see actually two bodies exerting force on each other. As per third law forces apply in pairs always.
So actually whenever we note a force there are actually two forces and two bodies interacting mutually.
Question 4
1 / -0

An unbalanced force:

A
never tends to change the state of motion of the body

B
tends to change the state of motion of the body

C
never exists

D
does not provide acceleration to a body

Solution

An unbalanced force tends to change the state of rest or of uniform motion of the body. This force provides acceleration or retardation to the body.
Question 5
1 / -0

Motion of a football after kicking is an example of:

A
balanced force

B
unbalanced force

C
both A and B

D
neither A nor B

Solution

Kicking a football, being an unbalanced force, sets the ball into motion. Therefore, Option (B) is correct.
Question 6
1 / -0

Name the property of matter due to which a body continues to be in its state of rest or uniform motion unless an external force acts on it :

A
Inertia

B
Elasticity

C
Viscosity

D
Density

Solution

Inertia is the tendency of any physical object to resist any change in its state of uniform motion or rest.
Question 7
1 / -0

The resultant of balanced forces is :

A
equal to infinity

B
Equal to zero

C
Not equal to zero

D
Equal to the acceleration produced in the body

Solution

Balanced forces cancel out the effect of each other resulting in a zero net force acting on the object.
Hence option B is correct.
Question 8
1 / -0

The acceleration in a body is due to:

A
Balanced force

B
Unbalanced force

C
Mass

D
Temperature

Solution

Unbalanced forces do not cancel out the effect of each other completely and thus resulting in a net external force acting in a particular direction causing the body to accelerate.
Question 9
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.
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.
