## Course Syllabus

### Welcome to PHYS101: Introduction to Mechanics

Specific information about this course and its requirements can be found below. For more general information about taking Saylor Academy courses, including information about Community and Academic Codes of Conduct, please read the Student Handbook.

### Course Description

Explore the physical underpinnings of our universe, the basic principles of physical laws, their application to the behavior of objects, and how we use the scientific method to advance our knowledge.

### Course Introduction

Physics is the branch of science that explores the physical nature of matter and energy. Physicists examine the story behind our universe, which includes the study of mechanics, heat, light, radiation, sound, electricity, magnetism, and the structure of atoms. They study the events and interactions that occur among the elementary particles that comprise our material universe.

In this course, we study the physics of motion from the ground up – learning the basic principles of physical laws and their application to the behavior of objects. Classical mechanics studies statics, kinematics (motion), dynamics (forces), energy, and momentum developed prior to the 1900 from the physics of Galileo Galilei and Isaac Newton. We encourage you to supplement what you learn here with the Saylor course PHYS102 Introduction to Electromagnetism.

Since mathematics is the language of physics, you should be familiar with high school level algebra, geometry, and trigonometry. We will develop the small amount of additional math and calculus you need to succeed during the course.

This course includes the following units:

- Unit 1: Introduction to Physics
- Unit 2: Kinematics in a Straight Line
- Unit 3: Kinematics in Two Dimensions
- Unit 4: Dynamics
- Unit 5: Rotational Kinematics
- Unit 6: Rotational Statics and Dynamics
- Unit 7: Work and Energy
- Unit 8: Momentum and Collisions

### Course Learning Outcomes

Upon successful completion of this course, you will be able to:

- identify common units and S.I. prefixes while using significant digits and converting units;
- use kinematic equations to solve one-dimensional linear-motion problems;
- use kinematic equations to solve two-dimensional problems such as projectile motion;
- use Newton's laws of motion to analyze and solve dynamic problems involving various types of forces such as the universal law of gravity;
- use centripetal force and rotational kinematics to solve problems involving objects in circular motion;
- solve statics and dynamic problems involving rotation;
- use the work-energy theorem and the conservation of energy law to analyze machines and to solve linear and rotational problems; and
- use conservation of momentum to solve elastic and inelastic collision problems for linear and rotational motion.

Throughout this course, you will also see learning outcomes in each unit. You can use those learning outcomes to help organize your studies and gauge your progress.

### Course Materials

The primary learning materials for this course are articles, lectures, and videos.

All course materials are free to access and can be found in each unit of the course. Pay close attention to the notes that accompany these course materials, as they will tell you what to focus on in each resource, and will help you to understand how the learning materials fit into the course as a whole. You can also see a list of all the learning materials in this course by clicking on Resources in the navigation bar.

### Evaluation and Minimum Passing Score

**Only the final exam is considered when awarding you a grade for this course. **In order to pass this course, **you will need to earn a 70% or higher on the final exam**. Your score on the exam will be calculated as soon as you complete it. If you do not pass the exam on your first try, you may take it again as many times as you want, with a 7-day waiting period between each attempt. Once you have successfully passed the final exam you will be awarded a free Course Completion Certificate.

There are also **end-of-unit assessments and practice problems** in this course. These are designed to help you study, and **do not factor into your final course grade**. You can take these as many times as you want until you understand the concepts and material covered. You can see all of these assessments by clicking on Quizzes in the course's navigation bar.

### Earning College Credit

This course is eligible for college credit via Saylor Academy's Direct Credit Program. **If you want to earn college credit, you must take and pass the Direct Credit final exam. That exam will be password protected and requires a proctor.** If you pass the Direct Credit exam, you will receive a Proctor Verified Course Certificate and be eligible to earn an official transcript. For more information about applying for college credit, review the guide to college credit opportunities. Be sure to check the section on proctoring for details like fees and technical requirements.

There is a **14-day waiting period** between attempts of the Direct Credit final exam. There is no waiting period between attempts for the not-for-credit exam and the Direct Credit exam. You may only attempt each Direct Credit final exam a **maximum of 3 times**. Be sure to study in between each attempt!

### Tips for Success

PHYS101: Introduction to Mechanics is a **self-paced course**, which means that you can decide when you will start and when you will complete the course. There is no instructor or an assigned schedule to follow. We estimate that the "average" student will take **33**** hours to complete this course**. We recommend that you work through the course at a pace that is comfortable for you and allows you to make regular progress. It's a good idea to also schedule your study time in advance and try as best as you can to stick to that schedule.

Learning new material can be challenging, so we've compiled a few study strategies to help you succeed:

- Take notes on the various terms, practices, and theories that you come across. This can help you put each concept into context, and will create a refresher that you can use as you study later on.
- As you work through the materials, take some time to test yourself on what you remember and how well you understand the concepts. Reflecting on what you've learned is important for your long-term memory, and will make you more likely to retain information over time.
- Although you may work through this course completely independently, you may find it helpful to connect with other Saylor students through the discussion forums. You may access the discussion forums at https://discourse.saylor.org.

### Technical Requirements

This course is delivered entirely online. You will be required to have access to a computer or web-capable mobile device and have consistent access to the internet to either view or download the necessary course resources and to attempt any auto-graded course assessments and the final exam.

- To access the full course including assessments and the final exam, you will need to be logged into your
**Saylor Academy account**and enrolled in the course. If you do not already have an account, you may create one for free here. Although you can access some of the course without logging in to your account, you should log in to maximize your course experience. For example, you cannot take assessments or track your progress unless you are logged in. - If you plan to attempt the optional Direct Credit final exam, then you will also need access to a
**webcam**. This lets our remote proctoring service verify your identity, which is required to issue an official transcript to schools on your behalf.

For additional guidance, check out Saylor Academy's FAQ.

### Fees

**This course is entirely free to enroll in and to access.** Everything linked in the course, including textbooks, videos, webpages, and activities, is available for no charge. This course also contains a free final exam and course completion certificate.

This course also has an **optional** final exam that can give you an opportunity to **earn college credit**. This exam requires the use of a proctoring service for identity verification purposes. **The cost for proctoring for this optional exam is $5 per session.**
