Exercises on Oscillations and Waves
Exercise 1.1
You nd a spring in the laboratory. When you hang 100 grams at the end of the spring
it stretches 10 cm. You pull the 100 gram mass 6 cm from its equilibrium position and
let it go at t = 0. Find an equation
Exercises on Work, Energy, and Momentum
Exercise 1.1
Consider the following two vectors:
A : magnitude 20, direction 37 North of East
B : magnitude 10, direction 45 North of West
Find the scalar product A B.
One could solve this problem two ways. First, t
Notes on Thermodynamics
The topic for the last part of our physics class this quarter will be thermodynamics. Thermodynamics deals with energy transfer processes. The key idea is that
materials have internal energy. The internal energy is the energy that
Notes on Introductory Mechanics
These notes are meant to help students understand the basic physics behind
introductory Newtonian mechanics. The ideas are presented in the order in which
they are taught in my rst year class, and are designed to supplement
Exercises on Thermodynamics
Exercise 1.1
Tom wants to measure his temperature using a thermocouple as a thermometer. He
denes temperature such that T is to be proportional to the thermocouple voltage.
He places the thermocouple in ice water (0 ), in boili
Supplimentary Notes III for Rotational Dynamics
So far we have only considered the motion of point objects. We have not allowed
the objects to rotate, nor have we considered how forces might produce a twisting
force. In this last section, the last 3 weeks
Notes on Oscillations and Mechanical Waves
The topics for the second part of our physics class this quarter will be oscillations
and waves. We will start with periodic motion for the rst two lectures, with our
specic examples being the motion of a mass at
Force and Motion
In the last section we demonstrated and discussed two fundamental laws of motion
and interaction: Newtons rst law and part of Newtons third law. (1) If an object
does not have any forces acting on it, it will oat along with a constant vel
Exercises on Force and Motion
Exercise 1.1
A small object is subject to two forces. One force has a magnitude of 5 units and a
direction due East. The other force has a magnitude of 10 units and a direction of
37 North of West. What is the net force on th
Notes on Fluid Dynamics
These notes are meant for my PHY132 lecture class, but all are free to use them
and I hope they help. The ideas are presented roughly in the order in which they are
taught in my class, and are designed to supplement the text. I wil
Exercises on Fluids and Gravity
Exercise 1.1
The Empire State Building in New York is around 320 meters tall. If we assume that
the density of air is 1.2 Kg/m3 throughout the height of the building, what is the
dierence in air pressure from the top to the
