- Q1
Which of the following statements about friction is TRUE?
Friction occurs between non-rubbing surfaces.
Friction acts in a direction similar to the direction of an object’s motion.
Friction opposes motion of objects.
Friction causes moving objects to move faster.
60s - Q2
Will it be easier for a person to push a table on a carpeted floor than on tiled floor?
Yes, because the carpeted floor is smooth, so friction is greater.
No, because the carpeted floor is rough, so friction is lesser.
Yes, because the carpeted floor is smooth, so friction is lesser.
No, because the carpeted floor is rough, so friction is greater.
60s - Q3
When can we say that friction on a floor is greater?
If the floor is tiled.
If the floor is smooth.
If the floor is wet.
If the floor is rough.
60s - Q4
Which force causes a rolling ball to stop after a few seconds?
magnetic
gravity
motion
friction
60s - Q5
Why is difficult to move heavy objects on a rough surface?
there is no friction on a rough surface
there is greater friction on a rough surface
there is lesser friction on a rough surface
rough surface is slippery
60s - Q6
When you are travelling along a road, how does the wet road affect friction?
It decreases friction.
It maintains friction.
It increases and decreases friction.
It increases friction.
60s - Q7
Which of the following forces cause objects to slow down and eventually stop?
air resistance
gravity
magnetic
friction
60s - Q8
What is the direction of friction between a moving object and a surface?
opposite to the direction of object’s motion
toward the direction of object’s motion
perpendicular to the direction of object’s motion
similar to the direction of object’s motion
