- Q1
Life would be impossible without force. Force affects the movement of objects. Which force causes a rolling ball to stop after a few seconds?
applied force
frictional force
gravitational force
normal force
300s - Q2
Friction affects all objects. Which of the following statements about friction is TRUE?
Friction opposes motion of objects.
Friction occurs between non rubbing surfaces.
Friction causes moving objects to move faster.
Friction acts in a direction similar to the direction of an object’s motion.
300s - Q3
Friction is a force that opposes the motion of two objects. Will it be easier for a person to push a table on a carpeted floor?
No, because the carpeted floor is rough, so friction is lesser.
No, because the carpeted floor is rough, so friction is greater.
Yes, because the carpeted floor is smooth, so friction is lesser.
Yes, because the carpeted floor is smooth, so friction is greater.
300s - Q4
A book on top of the table shows static friction. Which of the following statements describes static friction?
The strongest friction that keeps the book motionless
The strongest friction that keeps the book in motion.
The least friction that keeps the book motionless
The least friction that keeps the book in motion
300s - Q5
Static friction is a force that acts between objects in contact. Which of the following is an example of static friction?
A car skidding on the wet road.
A boy sliding on the smooth floor.
A flower vase on top of dining table.
A running horse with calesa (kalesa).
300s - Q6
What type of friction occurs when a body slides over a surface?
kinetic friction
static friction
stationary friction
rolling friction
300s - Q7
Friction is a force that affects the movement of an object. It makes objects stop or slow down because it opposes motion. Which of the following BEST describes kinetic friction?
It is a force that acts between non-moving objects.
It is a force that acts between moving objects.
It is a force that slows and stops moving objects.
It is a force that does not affect an object.
300s - Q8
A delivery man uses a wooden ramp when he delivers thus, packages do not slide off easily making his work take longer. What would be the best way to make the packages slide easily?
make his wooden ramp wider.
use water on his wooden ramp
make his wooden ramp narrower.
use a lubricant to polish and smoothen the ramp.
300s - Q9
The effect of friction can be desirable or undesirable. Which of the following shows undesirable effects of friction?
It allows you to grip things.
It reduces the speed of a moving vehicle
It converts energy to heat and noise.
It helps in converting one form of motion into another.

300s - Q12
When you touch your vocal cord as you talk, you can feel the vibrations inside. The number of vibrations must be about 20 to 20 000 in a second. What form of energy does it show?
electrical
heaT

300s - Q13
Sound is the movement of energy through a substance – like air or water. How is sound produced?
Sound travels in the form of molecules.
Sound is caused by vibrations.
Sound came from a vacuum.
