Directions:
Infer how friction affects movements of different objects. Read and answer the questions below. Write your chosen letter on a separate sheet of paper.


1. Which of the following statements about friction is TRUE?

A. Friction opposes motion of objects.
B. Friction occurs between non-rubbing surfaces.
C. Friction causes moving objects to move faster.
D. Friction acts in a direction similar to the direction of an object's motion.

2. Will it be easier for a person to push a table on a carpeted floorthan on tiled floor?

A. No, because the carpeted floor is rough, so friction is lesser. B. No, because the carpeted floor is rough, so friction is greater. C. Yes, because the carpeted floor is smooth, so friction is lesser.
D. Yes, because the carpeted floor is smooth, so friction is greater.

3. When can we say that friction on a floor is greater?
A. If the floor is wet.
B. If the floor is tiled.
C. If the floor is rough.
D. If the floor is smooth.
4. Which force causes a rolling ball to stop after a few seconds?
A. friction
B. gravity
C. magnetic
D. motion


5. Why is difficult to move heavy objects on a rough surface?
A. rough surface is slippery
B. there is no friction on a rough surface
C. there is lesser friction on a rough surface
D. there is greater friction on a rough surface


6. When you are travelling along a road, how does the wet road affect friction?
A. It increases friction.
B. It decreases friction.
C. It maintains friction
D. It increases and decreases friction.
