2.
Testing your prototype and redesign is a very important part of the engineering design process. Why?
a)
Redesigning and testing is so much fun!
b)
It fixes design issues, makes it better, and allows your solution to be as successful as possible.
c)
It allows you to make as many prototypes as you can.
d)
It allows you to ask questions and define problems.
3.

a)
trade-offs
b)
constraints
c)
patent
d)
engineers
5.
Which of the following was a constraint in the balloon powered car project?
a)
size
b)
time
c)
material
d)
internet resources
6.
What is the main transfer of energy taking place in the balloon racer car?
a)
thermal to sound
b)
potential to kinetic
c)
kinetic to potential
d)
sound to thermal
7.

a)
A car with a balloon with little air.
b)
A car with a balloon with medium air.
c)
A car with a balloon with a lot of air.
8.
Why doesn't the balloon racer car travel forever?
a)
The force of friction causes the balloon car to slow down.
b)
An outside force, like a wall or other object may make it stop.
c)
Both answers are correct
9.
You noticed your car did not travel as far as your neighbor's car. Which is one reason why?
a)
Your car had more mass and less force.
b)
Your car had more kinetic energy.
c)
Your car had less mass and more force.
d)
Your car had more potential energy.
10.
What is the first step in the engineering design process?
a)
research the problem
b)
identify the need or problem
c)
construct a prototype
d)
redesign
11.
After researching the problem, you should begin
a)
constructing a prototype
b)
redesign
c)
developing possible solutions
d)
testing and evaluating solutions
12.
Newton's 3rd law is demonstrated in the balloon racer by
a)
Car will stay at rest until an outside force acts on it.
b)
The more mass the car has the more force is needed to accelerate it.
c)
more air = more force which equals greater acceleration
d)
air pushes back out of balloon causing car to move forwar
13.
