PHY 126 Study Guide

Introduction
PHY 126 (General Physics II) is a 2- credit unit course for students studying towards
acquiring a Bachelor of Science degree. The course is divided into 4 modules and 11
study units. It will first introduce the elastic property of material. Next is hydrostatic.
This is followed by an extensive discussion of thermodynamics and statistical
mechanics (the zeroth law and the first law). Thereafter, elementary kinetic theory will
be studied.
The course guide therefore gives you an overview of what PHY 123 is all about, the
textbooks and other materials to be referenced, what you expect to know in each unit,
and how to work through the course material.

Recommended Study Time
This course is a 2-credit unit course having 11 study units. You are therefore enjoined
to spend at least 2 hours in studying the content of each study unit.

What You Are About to Learn in This Course
The overall aim of this course is to introduce you to the study of general Physics. At
the end of this course, you will:
Explain the concept of elasticity.
Describe hydrostatics.
Explain thermodynamics.
Describe ideal and real gases in elementary kinetic theory.

Course Aims
This course aims to introduce students to a wider scope of physics. It is expected that
the knowledge will enable the reader to effectively use the knowledge of physics in
his/her profession.

Course Objectives
It is important to note that each unit has specific objectives. Students should study
them carefully before proceeding to subsequent units. Therefore, it may be useful to
refer to these objectives in the course of your study of the unit to assess your progress.
You should always look at the unit objectives after completing a unit. In this way, you
can be sure that you have done what is required of you by the end of the unit.

i

, However, below are overall objectives of this course. On completing this course, you
should be able to:
(i). Define an elastic property of materials
(ii). Explain the moduli of elasticity
(iii). Describe the components of Hydrostatic
(iv). Describe surface tension and buoyancy-Archimedes’ principle
(v). Discuss the Zeroth law and the first law of thermodynamics
(vi). Explain the application of the first law of thermodynamics
(vii). Describe how ideal and real gases works when pressure is exerted on the walls
of a container

Working Through This Course
In order to have a thorough understanding of the course units, you will need to read
and understand the contents, practice the steps, and be committed to learning and
implementing your knowledge.
This course is designed to cover approximately sixteen weeks, and it will require your
devoted attention. You should do the exercises in the Tutor-Marked Assignments and
submit to your tutors.

Course Materials
The major components of the course are:
1. Course Guide
2. Study Units
3. Text Books
4. Assignment File
5. Presentation Schedule

Study Units
There are 11 study units and 4 Modules in this course. They are:

Module One Unit 1: Elastic Property of Materials
Unit 2: Moduli of Elasticity
Unit 3: Elastic Property of Materials

Module Two Unit 1: Surface Tension
Unit 2: Buoyancy-Archimedes’ Principle
Unit 3: Pressure

Assignment File
The assignment file will be given to you in due course. In this file, you will find all the
details of the work you must submit to your tutor for marking. The marks you obtain
for these assignments will count towards the final mark for the course. Altogether,
there are tutor marked assignments for this course.

Presentation Schedule
The presentation schedule included in this course guide provides you with important
dates for completion of each tutor marked assignment. You should therefore
endeavour to meet the deadlines.

Assessment
There are two aspects to the assessment of this course. First, there are tutor marked
assignments; and second, the written examination. Therefore, you are expected to
take note of the facts, information and problem solving gathered during the course.
The tutor marked assignments must be submitted to your tutor for formal assessment,
in accordance to the deadline given. The work submitted will count for 40% of your
total course mark.
At the end of the course, you will need to sit for a final written examination. This
examination will account for 60% of your total score. You will be required to submit
some assignments by uploading them to PHY 123 page on the u-learn portal.

iii

, Tutor-Marked Assignment (TMA)
There are TMAs in this course. You need to submit all the TMAs. The best 10 will
therefore be counted. When you have completed each assignment, send them to your
tutor as soon as possible and make certain that it gets to your tutor on or before the
stipulated deadline. If for any reason you cannot complete your assignment on time,
contact your tutor before the assignment is due to discuss the possibility of extension.
Extension will not be granted after the deadline, unless on extraordinary cases.

Final Examination and Grading
The final examination for PHY 123 will last for a period of 2 hours and has a value of
60% of the total course grade. The examination will consist of questions which reflect
the Self-Assessment Exercise(s) and tutor marked assignments that you have
previously encountered. Furthermore, all areas of the course will be examined. It
would be better to use the time between finishing the last unit and sitting for the
examination, to revise the entire course. You might find it useful to review your TMAs
and comment on them before the examination. The final examination covers
information from all parts of the course.

Practical Strategies for Working Through This Course
1. Read the course guide thoroughly
2. Organize a study schedule. Refer to the course overview for more details. Note
the time you are expected to spend on each unit and how the assignment relates
to the units. Important details, e.g. details of your tutorials and the date of the first
day of the semester are available. You need to gather together all this information
in one place such as a diary, a wall chart calendar or an organizer. Whatever
method you choose, you should decide on and write in your own dates for working
on each unit.
3. Once you have created your own study schedule, do everything you can to stick
to it. The major reason that students fail is that they get behind with their course
works. If you get into difficulties with your schedule, please let your tutor know
before it is too late for help.
4. Turn to Unit 1 and read the introduction and the Learning Content for the unit.
5. Assemble the study materials. Information about what you need for a unit is given
in the table of content at the beginning of each unit. You will almost always need
both the study unit you are working on and one of the materials recommended for
further readings, on your desk at the same time.
6. Work through the unit, the content of the unit itself has been arranged to provide
a sequence for you to follow. As you work through the unit, you will be encouraged
to read from your set books
