●● Physics is concerned with describing the interactions of ____, _____,
_____, and _____.
Answer: energy, matter, space, and time
●● What is a systematic process to find the solution to a problem?
Answer: Scientific method
●● There are two kinds of basic proportionalities in science. From the
list below, select the name of these two types of scientific
proportionalities.
A. Direct proportion
B. Indirect proportion
C. Inverse proportion
Answer: A. Direct proportion
C. Inverse proportion
●● What are the six steps of Karl Pearson's scientific method?
,Answer: 1.) Identify the Problem
2.) Gather Information
3.) Form a Hypothesis
4.) Expand the Hypothesis
5.) Test the Hypothesis
6.) Evaluate the Hypothesis
●● In an experiment, you show that as you increase the force acting on
an object, the acceleration of the object also increases. This is an
example of which kind of proportion?
Answer: Direct proportion
●● As you increase the pressure on a gas, the volume of this gas
decreases. This is what kind of proportion?
Answer: Inverse proportion
●● A good hypothesis is both _________ and ________.
Answer: plausible, testable
, ●● In an experiment, you drop a ball and time how long it takes for it to
fall to the ground. You then drop the ball again from a higher height and
time it again. You continue this pattern for several more trials, each time
you keep increasing the height and timing how long it takes to fall. In
every trial, you use the same ball.
Independent, dependent, or controlled variable
Height of drop:
Answer: Independent variable
●● In an experiment, you drop a ball and time how long it takes for it to
fall to the ground. You then drop the ball again from a higher height and
time it again. You continue this pattern for several more trials, each time
