Weekly Quiz Competition

Question 1
1 / -0

Fill in the blanks:
Force comes into action when ________.

A
objects interact.

B
objects do not interact.

C
object move.

D
None of these

Solution

When two body interact with each other then momentum of body will change that change in momentum of the body is effect of mutual force between them.
Question 2
1 / -0

Fill in the blanks:
The net force is ______ than the individual applied forces.

A
Either larger or smaller

B
Always smaller

C
Always greater

D
Always equal

Solution

The net force is the resultant force of all the individual applied forces. So, the force is either larger or smaller than individual forces, because force is a vector quantity.
Question 3
1 / -0

What brings a change in the state of the motion of an object?

A
The path of motion

B
Mass of the object

C
Force acting on the object

D
Density of the object

Solution

The speed and direction of motion can be changed by applying force on an object and thus a force can bring a change in the state of motion of an object.
Question 4
1 / -0

Change in state of motion of an object can be described as:

A
change in speed only.

B
change in direction of motion only.

C
change in either speed or direction.

D
change in neither speed nor direction.

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.
Question 5
1 / -0

The application of a force would result in a change in the state of motion of an compressible object. The given statement is:

A
Always true.

B
Not always true.

C
Always false.

D
Insufficient information

Solution

Many a times, application of force does not result in a change in the state of motion. For example, no effect of force in the state of motion is observed when you try to push a wall.
Question 6
1 / -0

What happen when a lump of dough on a plate is pressed down with your hands?

A
Change in state of motion takes place.

B
Change in shape takes place.

C
Change in mass takes place.

D
Both B and C

Solution

Here, applied force changes the shape of the dough and compresses it. The dough still remains in a state of rest.
Question 7
1 / -0

If you push a light object continuously, its speed:

A
will keep on increasing.

B
will keep on decreasing.

C
will remain same.

D
will become zero.

Solution

If the force applied on the object is in the direction of its motion, the force aids the motion of the object and hence the speed of the object increases.
Question 8
1 / -0

What happens when a ball is set in motion by pushing it along a level surface and a moving ball strikes a small stone in its path?

A
The direction of motion of the ball changes.

B
The direction of motion of the ball remains the same.

C
The moving ball stops.

D
The ball bursts.

Solution

When a moving ball strikes a small stone in its path, the stone applies a force on the ball and the speed of the ball reduces and the direction of the ball changes.
Question 9
1 / -0

What happens to the speed of the object when the applied force is in the opposite direction to the direction of motion?

A
Speed increases.

B
Speed decreases.

C
Speed remains the same.

D
None of the above

Solution

If the force is applied in the direction opposite to the direction of motion, it opposes the motion of the object and hence the speed of the object decreases.
Question 10
1 / -0

In pressing a rubber ball placed on a table, the application of force leads to:

A
a change in the shape of the object.

B
a change in the state of the motion of the object.

C
a change in the mass of the object.

D
no change anywhere.

Solution

On pressing a rubber ball placed on a table, the ball get compressed and hence, the shape of the ball changes.

The state of motion of the ball doesn't change. It is because when we press the ball, the ball presses the table surface. The table surface applies an equal and opposite force on the ball. Therefore, the net force on the ball is zero so it doesn't change its state of motion.

The mass remains unchanged because we are not removing any portion of the ball. We are not changing the amount of matter contained by the ball. The force applied only brings the particles of the ball closer to compress it.
