PHYSICS MATH REVIEW
UNDERSTANDING THE LANGUAGE OF PHYSICS
This optional preparatory course is for students
registered in Physics 115.3 to review math
concepts and techniques that are used in a
first-year physics course.
Topics include
linear, quadratic
Earths Magnetic Field
The Earths geographic north pole
corresponds to a magnetic south pole.
The Earths geographic south pole
corresponds to a magnetic north pole.
Strictly speaking, a north pole should be a northseeking pole and a south pole a south-s
Estimates
Can yield useful approximate answers
An exact answer may be difficult or impossible
Mathematical reasons
Limited information available
Can serve as a partial check for exact
calculations
Examples in Class
Section 1.6
Estimate the order of m
Quiz 1
Question 1:

SI?
A. meter
B. foot
C. centimeter
Question 2:
The age of universe is:
A. 5,000 teraseconds
B. 500 petaseconds

Quiz 2
If a is acceleration, v is velocity, x is
position and t tis time, then
Emission Spectrum of Hydrogen Equation
The wavelengths of hydrogens spectral lines can be
found from
RH is the Rydberg constant
RH = 1.097 373 2 x 107 m-1
n is an integer, n = 1, 2, 3,
The spectral lines correspond to different values of n.
