Physics Classroom is making strides to make our site accessible to
everyone, and features many accessibility features.
Our site contains 6 navigation areas. The Primary, Secondary,
and Page Level navigations have a screen reader version of their nav
structure that allows using the left and right keys to navigate sibling
navigation items, and up or down keys to navigate parent or child
navigation items. The others can be navigated using tabs.
Within the main content, we leverage headers to provide in page or
in tool navigation.
Although we are still rebuilding our content to leverage these tools,
our images should have both short and verbose descriptions, the later
describing in great detail the image for those who cannot see. Any
formulas found within the images are often in the image figure below the image.
Equations and formulas are rendered using MathJax, which has both verbal,
braille (including nemath braille), and keyboard navigation within them.
Learn how to configure and leverage this for various screen readers on our
Equation Navigation Page.
While not every area of
Physics Classroom is usable purely from keyboard and screen reader, we
are committed to continue work on making this possible. If you have
questions or need additional help, please use

Position-Time Graphs: Changing Speed Motion Video Tutorial
The Position-Time Graphs: Changing Speed Video Tutorial discusses the features of a position-time graph for the motion of objects that have a changing velocity. Numerous examples, illustrations, and animations assist in the explanations.
The video lesson answers the following questions:
What does a position-time graph look like for a changing velocity motion?
How is a speeding up and a slowing down motion represented on a position-time graph?
How can the direction of the velocity and acceleration be determined from a position-time graph?
Physics Interactives: Graphs and Ramps
This interactive simulation has a game-like feel as users design ramps along which balls will roll. The goal is to design a ramp that leads to a motion that matches a specific position-time graphs. Great practice and you'll love it.
Concept Builder: Position-Time Graphs - Conceptual Analysis
The consensus is Concept Builders are phun! They include a collection of questions to answer; feedback to your answers is immediate. Each question includes a Help page. Dataways, stars, and trophies are your rewards as you apply Physics principles to work your way through a variety of difficulty levels. Any of the three activities would serve you well at this point.
Concept Builder: Dots and Graphs
The consensus is Concept Builders are phun! They include a collection of questions to answer; feedback to your answers is immediate. Each question includes a Help page. Dataways, stars, and trophies are your rewards as you apply Physics principles to work your way through a variety of activities. The first activity is a perfect complement to this video tutorial.
MOP the App #1: Kinematics Graphing, Missions KG1 - KG3 on Position-Time Graphs
You may not find a better exercise for putting knowledge to practice than the Minds On Physics program. Available as an app on several devices, the MOP program consists of carefully crafted questions that target discrete concepts. Any of the three mentioned missions will provide the work-out required to solidify your understanding of this video.

Teacher Resources
Teacher Toolkits - Position-Time Graphs
We love our Teacher Toolkits. These short Toolkits were made for busy teachers. They include annotated links to a variety of vetted, standards-based, multimedia-supported resources across he web. We have one on the topic of Position-Time Graphs. Check it out!
Curriculum Corner - Kinematic Concepts
Don't overlook our Curriculum Corner. It is the in-the-trenches curriculum on our website and coordinates well with the Tutorial and other sections. It includes a variety of classroom-ready Think Sheets that can be used with your classes. Depending on your interests and needs, you will find 3-5 Think Sheets that address the topic of Position-Time Graphs.
Physics Interactives: Graphs and Ramps
This is a great interactive exercise that gets students thinking. It is best used after the videos (or comparable instruction) on the topic of both constant speed and changing speed motion. The goal of this game-like activity is to design a ramp that leads to a motion that matches a specific position-time graph. Its a good challenge and a captivating activity.
Concept Builder: Position-Time Graphs - Conceptual Analysis
Students like Concept Builders. They consist of a battery of questions which are delivered in random order. Feedback to student answers is immediate. When questions are missed, a similar question is given. Stars and trophies are used as a progress-tracking tool to help teachers assess student understanding. This CB has three activies. It's a great exercise once a constant speed and a changing speed understanding is developing.
Concept Builder: Dots and Graphs
Here is another Concept Builder that makes for a great formative assessment. This CB has three activies. It's recommended after a constant speed and a changing speed understanding is developed. The first activity pertains to position-time graphs. Other activities require an understanding of velocity-time graphs.
MOP the App #1: Kinematics Graphing, Missions KG1 - KG3 on Position-Time Graphs
The Minds On Physics program provide students a rigorous exercise in thinking, analyzing, and using Physics concepts. Available as an app on several devices, the MOP program consists of carefully crafted questions that target discrete concepts. Any of the three mentioned missions will provide the work-out required to solidify your understanding of this video. You will find them in the Kinematic Graphing module of App #1.
We have many other online activities ... particularly in the Physics Interactives and Concept Builders section. Most require a dual understanding of both position-time and velocity-time graphs. So please return after both graphical understandings have developed.
