Correct!
The chair will support me when I sit on it because it looks strong.
Belief
Using the principle of cushioning we can make a more comfortable chair.
Technology
t!
Using the principle of tensile strength, we can show people how the chair supports someone when he or she
sits on it.
Science
rect!
Using the equations for kinematics we can determine that when we drop the chair it will start with an
acceleration of 9.8 m/s2.

, Question 9
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?rrect!
Direct proportion
Question 10
As you increase the pressure on a gas, the volume of this gas decreases. This is what kind of proportion?
Inverse proportion
Question 11
A good hypothesis is both _________ and ________.
Answer: plausible, testable – either order
Question 12
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. For this
experiment, match up the measurement in the left column to the type of variable it is from the list in the right
column.Answered
Height of drop: Independent variable
Mass of ball: Controlled variable
Time of fall: Dependent variable
Question 13
What is defined as prejudice in favor of or against one thing, person, or group compared with another, usually
in a way considered to be unfair? [answer1]
Correct Answers: Bias
Question 14
During an experiment, the mass of a cart is increased and the acceleration of it is measured, while all other
variables remain constant. Below are the data. According to these data, what relationship exists between mass
and acceleration? Also, explain how the data indicate this relationship.
Acceleration
Trial Mass (kg)
(m/s2)
1 0.100 2.00
2 0.200 1.75
3 0.300 1.50
4 0.400 1.25
5 0.500 1.00
Your Answer:
Inverse proportion – As the mass is increased, the acceleration decreases
Question 15
During an experiment, the force exerted on a cart is increased and the acceleration of it is measured, while all
other variables remain constant. Below are the data. According to these data, what relationship exists between
force and acceleration? Also, explain how the data indicate this relationship.
Trial Force (N) Acceleration (m/s2)
1 250 1.50
2 350 1.75
3 450 2.25
4 550 3.00
