Essay Concept Regions: Final Exam 

1 
Momentum: Linear and
angular 

1A 

External force exists 

1B 

""""""""""""""does
not exist 

1C 

External torque exists 

1D 

""""""""""""""does
not exist 



2 
Strength of materials: 

2A 

Modul. 
Stress/strain 

2B 

K=F/x 

2C 

Y=F/A divided by delta L/L 

2D 

Bulk Mod.=P/delta V/V 



3A 
Fluids: 
Fluids under fluids; p=dgh 

3B 

Pascal Prin.: F/A
= f/a 

3C 

P = same in fluid 

3D 

Archimedes Prin. 

3DA 

Wt. fluid displaced = Buoyant force 

3DB 

How used to get density of
objects…remember lab we did. 

3E 

Bernuillie's Principle. 

3EA 

Work energy theorem for multiple
particles. 

3EB 

W/V = delta K/V + delta U/V 

3EC 

velocity of fluid = inverse proportional to
pressure. Varies inverse to each 
3F 

Eq. of continuity: VA =va, Vol/unit
time at one point 

other. 





is Vol./unit time at another point
in pipe 



4A 
Simple Harmonic Motion: Penduliums and spring mass motion(frequency) and period. 
4B 

What does f and T depend on and is
that reasonable? 



5A 
Waves: 
v = (wave length) X frequency 
Where is this OK? 

5AA 

When wave length is up, what happens
to frequency? 

5AB 

………and vice versa 

5BA 

Transverse and longitudinal waves?
What are they and what is the motion of 

5BB 

medium they are in. Where do we find
each type? 

5CA 

Waves on strings, harmonics on
strings and standing waves. 



5DA 

frequency of vibes on string = 



5EA 

Standing waves in tubes. If you know
one f, how can you get another? 



6A 
Sound: 
Echos 

6B 

Intensity is measured in dBs. What
are intensity units? 



6CA 

Doppler? What does that say about
waves going away or toward some receiver? 


A receiver could be your ears
listening to cars passing on street. 



6CB 

How do cops use the doppler effect
to give you a prize ticket? 



6CC 

How do doctors use the doppler
effect to find the speed of your blood? 


6CE 

What is the red shift all about?
