PISA QUESTIONS IN THE PRETEST FOR PHYSICS
Quiz by Kim Dela Cruz
Tag the questions with any skills you have. Your dashboard will track each student's mastery of each skill.
​"You are observing the motion of a car during a test drive. The car starts from rest at a traffic signal. Over the first 5 seconds, the driver gradually increases the speed by pressing the accelerator pedal uniformly. Once the car reaches a steady cruising speed, the driver maintains that constant velocity for the next 10 seconds."
What does the horizontal line on the velocity-time graph from 5 to 15 seconds represent about the car's motion? (Select three correct answers)
​A bus is driving along a straight stretch of road. The bus driver, named Ray, has a cup of water resting on the dashboard: Suddenly Ray has to slam on the brakes.
What is most likely to happen to the water in the cup?
 The water will spill over side 2.
The water will stay horizontal.
The water will spill over side 2.
The water will spill over side 1.

The electromagnetic spectrum is a range of frequencies, wavelengths and photon energies covering frequencies from below 1 hertz to above 1025Â Hz, corresponding to wavelengths which are a few kilometres to a fraction of the size of an atomic nucleus in the spectrum of electromagnetic waves as shown in diagram below.
Use the model to rank the following bands of the EM spectrum by frequency.Â
Block A starts with initial speed \[v\] and slides down a frictionless incline of height \[h\]. Block B is thrown horizontally with speed \[v\] from height \[h\]. The blocks are identical.
Which block hits the ground with the greatest speed?
Bicycle on a Hill
A cyclist is riding up a hill at a constant speed. Which of the following statements explains why the cyclist is not accelerating?
 Two small spheres are charged with opposite types of charge and placed a certain distance apart. If the charge on one sphere is doubled, what happens to the electrostatic force between the spheres?
In many countries, images can be taken of a fetus (developing baby) by ultrasound imaging (echography). Ultrasounds are considered safe for both the mother and the fetus.
The doctor holds a probe and moves it across the mother’s abdomen. Ultrasound waves are transmitted into the abdomen. Inside the abdomen they are reflected from the surface of the fetus. These reflected waves are picked up again by the probe and relayed to a machine that can produce an image.
Can ultrasound examinations of expectant mothers provide answers to the following questions?
An image of a fetus can also be obtained using X-rays. However, women are advised to avoid having X-rays of their abdomens during pregnancy.
Why should a woman avoid having her abdomen X-rayed during pregnancy in particular? (2 answers are need)
