Weekly Quiz Competition

Question 1
1 / -0

Identify the action involved in opening or shutting a door.

A
Pulling

B
Pushing

C
Both a and b

D
None of the above

Solution

We need to apply a PULL when trying to open a door.
We need to apply a PUSH when trying to close a door.
Question 2
1 / -0

In which direction does a car at rest move when pushed by a few persons?

A
In the direction opposite to push

B
In the direction of the push

C
Making an acute angle with the push

D
None of the above

Solution

To move a car there must be interactions between the men and the car. The interaction is exerted in terms of push and the car moves in the direction of net force which is the direction of push, i.e., in the direction of the force applied.
Question 3
1 / -0

When you and your friend push a table in opposite directions, it becomes difficult to move. This is because:

A
the net force becomes the sum of the two forces.

B
the net force becomes the difference of the two forces.

C
the table becomes heavier.

D
the table becomes lighter.

Solution

When two forces are applied in opposite directions, the net force becomes the difference of the two. So, the net force becomes small and the table becomes difficult to move.
Question 4
1 / -0

In the game of tug-of-war, the team that pulls the rope harder wins the game. This is because:

A
the rope moves in the direction of larger force.

B
the rope moves in the direction of the smaller force.

C
the rope does not move at all.

D
the rope moves in the direction of product of the forces.

Solution

In a game of tug-of-war, teams apply forces in terms of pulls on the rope. On the rope, two pulls act in opposite directions. The net force becomes the difference of the two forces (pulls) and the rope moves in the direction of the larger force (pull).
Question 5
1 / -0

What happens when there is no interaction between the objects?

A
Force comes in action.

B
Force does not come in action.

C
Force may or may not come in action.

D
None of the above is correct

Solution

There are two types of force
1) Interactive force: Its effect comes when two objects will come in contact.
2) Non- Interactive force: Its effect will come when an object comes in their respective field strength.
exp: Charge in an electric field, Mass in gravitation field.
Hence Option C.
Question 6
1 / -0

When you and your friend pushes heavy table in the same direction, it becomes easier to move. This is because:

A
the net force is the sum of forces.

B
the net force is the difference of forces.

C
the table becomes lighter.

D
friction reduces.

Solution

When you and your friend pushes heavy table in the same direction, the force applied by you and your friend get added. So, applied forces sum up to get a larger force. Hence the table moves easily.
Question 7
1 / -0

What happens when two forces are applied in the opposite direction on an object?

A
Net force is the addition of forces.

B
Net force is the subtraction of forces.

C
Net force is the division of forces.

D
Net force is the multiplication of forces.

Solution

When two forces are applied in the opposite direction on an object, the net force will be the difference between the two forces.Because both forces in opposite direction opposes each other.Hence net effect is reduced.
Question 8
1 / -0

Fill in the blanks:
In the game of tug-of-war, both the teams pulls each other. So ________.

A
force is applied due to interaction.

B
force is not applied although there is interaction.

C
force is applied although there is an interaction.

D
none of the above.

Solution

Force always comes into action when there will be interaction between the objects, Here both the teams are exerting force on each other through the rope.
Question 9
1 / -0

What happens when two forces are applied to an object in the same direction?

A
Forces add up

B
Forces subtract

C
Resultant force is the division of forces

D
None of the above

Solution

When two forces are applied on a object in the same direction, forces added up and net force increases.
Question 10
1 / -0

Fill in the blanks:
A force applied on an object can change its ________.

A
mass

B
state of motion

C
temperature

D
None of the above

Solution

A force applied on an object can change its state of rest or motion and its shape or size.
