PhysicsEq is a course in Mechanics, the study of motion. It covers the topics typically treated in the Mechanics unit of an introductory algebra based college course, a college prep high school class or Advanced Placement Physics B. Although algebra based, it can be an asset to students in an introductory calculus based course where the concepts of Physics can be lost in striving to master the math at the same time as the Physics. The purpose of this course is to build an understanding of the concepts of Mechanics using the equations as guides. Proportions and graphing are extensively used to develop a feeling for how the variables described by a particular equation relate to one another. Some particular problems are used as examples but the principal focus is how concepts, in the form of equations, can be used and combined to solve for problems in general. The sections include multiple choice questions but they are generally there to help you digest and apply the concepts. Sections are formatted with scrollable text on the right and an images area on the left. A section contains, on average, 10 subsections each of which displays a new image, slide show, animation or mini-sim in the image area. There are also 26 simulations which occupy their own full screen and allow you to set certain variables and view the results. The simulations have their set of "notes", instructions which help you learn the most from a given simulation. Navigating in PhysicsEq is versatile either with button presses or by swiping and tapping various regions of the screen. An index allows selecting sections by name from a menu. A button press in the main screen accesses the EquationCards or the Glossary. There is a preferences pane allowing you to change the appearance of the interface. PhysicsEq contains: 49 content sections with over 750 images 26 simulations 15 mini simulations 15 animations ("movies") 129 multiple choice questions 21 EquationCards, each with a key equation of Mechanics, its meaning, conditions, units and pertinent information 63 item glossary of key terms, accessible from table and embedded in context Chapters for the seven subunits are listed below: • Introduction: Measurement, Position, Displacement, Proportions, Graphing, Velocity, Problem Solving. • Linear Motion: Acceleration, Instantaneous Velocity, Linear Motion, Area Under a Curve, Freefall, Vector Addition. • 2D Motion: 2D Motion, Vector Angles, Projectile Motion, Vector Resolution. • Forces: Forces, Newton's 1st Law, Newton's 2nd Law, Tour de Forces, Newton's 3rd Law, Forces In One Dimension, Systems, Forces In Two Dimensions, Friction, Statics. • Energy: Energy, Work, Kinetic Energy, Gravitational Energy, Work-Energy Principle, Elastic Energy, Other Forms of Energy, Conservation of Energy, Energy and Friction, Energy In Action, Power. • Momentum: Impulse and Momentum, Conservation of Momentum, Collisions In 2D • Circular Motion and Gravitation: Uniform Circular Motion, Universal Gravitation, G Fields and Satellites, Torque, Simple Harmonic Motion. PhysicsEq runs natively on iPad and iPhone/iPod touch and is fully optimized for retina display. I've taught Physics for over 20 years. My AP Physics students were highly successful on the AP Exams; I've endeavored to incorporate some of what I imparted to them into PhysicsEq. If you own PhysicsEq feel free to email me with comments or suggestions.

There are motion maps, lots of graphs, and good concise explanations along with interactive graphs and review questions. I especially like that students aren't simply given a way to plug numbers into boxes and get answers. This app actually teaches the basic concepts. It's not perfect but I really like it! ### 5/5 — Well done *2014-04-17, version 1.2* This application provides great animations accompanied by thorough, conceptually complete descriptions. It can be easy to lose your place in each lesson, and the transitions are not the most intuitive, but still, this application is great and I'm looking forward to other physics apps, like for electricity and magnetism. ### 5/5 — Dr. *2013-08-22, version 1.0* Clear, concise and practical, PhysicsEq makes the concepts very accessible. Who says physics can't be fun? ### 5/5 — Teacher *2013-08-22, version 1.0* I am impressed with the clarity of the explanations. The interactive simulations help bring concepts to life. It's like having a physics tutor in your phone! ## Frequently asked questions about PhysicsEq ### What topics does PhysicsEq cover?
