10
The ball is rolling down the ramp. What frictional forces are acting on it?
Truss friction and rolling friction
Rolling friction and drag
Dora and Steve
Normal friction and cool friction
11
What energy does it have at point D?
Kinetic Energy

12
Which of Newton's Laws say that each action has an equal and opposite reaction?
First
Third
Fourth
Second
13
Which of Newton's laws say that the rocket will keep moving in space with the engines off?
Fifth
Second
First
Third
14
How is velocity different from speed?
Tacos have velocity, burritos have speed.
Velocity is speed in a direction, and speed is how fast something is going.
Velocity is acceleration, and speed is just how fast something is going.
Velocity and speed are always the same.
15
Which of Newton's laws is about inertia?
Third
Second
None
First
16
What is the equation for acceleration?
a=t\times\sqrt{v}
a=\frac{Δv}{Δt}
a=b\times c\times d\times e
a=v\times t
17
Which of Newton's laws is depicted in the image below?
First
Second
Fourth
Third
18
What is the volume of the figure below?
Not enough numbers to determine volume.
100 cm3
75 cm3
25 cm3
19
Which is NOT a method of heat transfer?
Convection
Radiation
Wax Paper
Conduction
20
Still talking about you flying through the air as a human cannonball, what is your vertical acceleration?
0 m/s2
It's decreasing as you go.
-9.81 m/s2
-400 m/s2
21
What kind of bridge is this?
Steve
Cable-stayed
Suspension
Truss
22
What is the formula for density?
Density = Wood Glue + Smurfs
Density = Mass / Volume
Density = Volume - Mass
Density = Mass + Volume
23

The Physics of Engineering
Marine Eco... Haha just kidding, The Physics of Engineering
Examining the Physics of Engineering
24
What kind of energy does this ball have at point A? (Assume the ball is sitting at the top of the hill, about to roll)
Elastic Potential Energy
Gravitational Potential Energy
Sitting Energy
Kinetic Energy
25

First
Third
Fourth
Eleventh
26

3.09 m/s2
110 m/s2
It depends on your mass.
9.81 m/s2
29
The acceleration of a falling object...
increases over time.
is 0.
is constant over time.
decreases over time.
30
Which of Newton's laws predict the tank rocks back when firing the shell?
Seventeenth
Fifth
Second
Third
31
What is the equation for speed when give distance and time?
speed = distance x time
speed = acceleration + time
speed = distance + time x Steve
speed = distance / time
32
Heat rises because...
Steve pushes hot air up.
Hot air is made of different gases than cold air.
Hot air is less dense than cold air.
Gravity doesn't like hot air.
33
