Question 1
A student claims that a heavier ball will hit the ground before a lighter ball when both are dropped from the same height in a vacuum. Which of the following best describes how a teacher should guide the student to test this claim scientifically?
Correct Answer:
Design a controlled investigation in which mass is the only variable changed while air resistance is eliminated, then compare fall times
Question 2
In an experiment measuring the period of a pendulum, a student measures the time for 20 complete swings rather than a single swing. What is the primary advantage of this technique?
Correct Answer:
It reduces the relative effect of human reaction-time error in the measurement
Question 3
A measured value is reported as 4.50 cm. How many significant figures does this measurement contain, and what does the trailing zero communicate?
Correct Answer:
Three significant figures; the trailing zero indicates precision to the hundredths place
Question 4
Which of the following correctly distinguishes the accuracy and precision of a set of measurements?
Correct Answer:
Accuracy describes how close measurements are to the true value; precision describes how close measurements are to one another
Question 5
A graph of an object's position versus time produces a straight line passing through the origin with a positive slope. What does the slope of this line represent?
Correct Answer:
The constant velocity of the object
