Throughout the semester you will work as part of 3 person team

* Organize yourselves into teams of 3

* When you are happy with your team register your team on a computer and record your team number eg 7REG14

* Complete questionnaire and place in the box at front of lab

Rotation system – Preparatory Work marked at the start of each session. Zero mark recorded if not completed before the lab class.

Teams

1 to 8: 1st column Collisions

9 to 16: 2nd column Terminal Velocity

17 to 24: 3rd column Liquid Flow (1)

constant:

“power”

T = k an

variable:

length of semi-major axis

variable: period of orbiting body

constant:

k = 2 / (G1/2MS1/2)

How do we find the values of the constants?

EXCEL: 5.791010 5.79e10

y = ??x??

R2 = ??

power fit using EXCEL trendline

period T (s)

semi-major axis a (m)

(0,0)

T = k an

lbf

log(T)

EXCEL – linear fit

y = ??x + ??

R2 = ??

LINEST command:

slope & uncertainty

intercept & uncertainty

log(a)

(0,0)

slope = n n

T = k an

log(T) = n log(a) + log(k)

intercept = log(k)  log(k)

k = 10intercept

(kk+k-)

Identify / Setup

hman

hcyl

Execute

straight line through origin y = m x

(0, 0)

Execute

1 significant figure for uncertainty, hence, one decimal place  best estimate also one deciaml place

uncertainty: difference between slopes ‘lbf’ and ‘lwf’or linest command

relative density

slope of ‘lbf’

Evaluate

You will have two results: your paper graph results and the result from the Excel analysis

s.f. ok units ok

value sensible man > cyl since hcyl > hman

Do not follow instruction in lab manual (pages 1.10 – 1.11)

From your estimate of the relative density calculate the density of the liquid in the manometer knowing that the density in the cylinder is water. Compare your value of the density of liquid in the manometer with the value determined by the hydrometer
