## Teacher Resources

The Physics Classroom has been devoted to helping students, teachers, and classrooms since the 1990s. We are as passionate about that mission now as we have ever been. If you are a teacher of Physics or Physical Science, we encourage you to use our Video Tutorial with your students. And we also encourage you to consider the use of other resources on our website that coordinate with the video. We have listed a few below to help you get started.

Curriculum Corner, Circular Motion and Gravitation

Get students active and thinking with our free Think Sheets from the Curriclum Corner section of our website. The following Think Sheet is a reasonably good fit to this video:

Universal Gravitation

Try a Teacher Toolkit ... you might be very glad that you did. Each toolkit includes annotated links to vetted resources from across the web that we feel reliably support the specific topic. Give this one on universal gravitation a try.

Calculator Pad, Circular Motion and Gravitation Problem Set, Problems #19-21

Our Calculator Pad problem sets provide a collection of problems, with answers, and audio-guided solutions. For a student attempting to learn how to use a physics equation, you couldn't ask for more.

Concept Builders, Circular Motion and Satellite Motion section, Gravitational Field Strength

Concept Builders provide students an opportunity for practice with immediate feedback and opportunities for correction. A Help Me! button is available for each question. This one on gravitational field strength provides support for this video.

A Minds On Physics mission provides students a great workout in close reading, analytical thinking, and conceptual reasoning. They're difficult but there's a Help button waiting to assist. Those who endure the frustration of getting questions wrong will come out of the exercise and get it right on the test. That's a win!

Physics Interactives: Value of g on Earth

This activity (referenced on Slide 4 of the video) allows you to click at various locations on a globe and view the value of g at that location. There are some surprising results.

Physics Interactives: Value of g on Other Planets

This activity (referenced on Slide 5 of the video) provides an easy interface for viewing the value of g on other planets in our Solar System.

The Tutorial, Circular and Satellite Motion Chapter: The Value of g

This page from our written Tutorial section mirrors much of the video and is a great reference for students. Many teachers include a link to it on their course page.
