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 two Think Sheets are a reasonably good fit to this video and the one that follows in the series on Circular and Satellite Motion:

Universal Gravitation

The Inverse Square Law of Universal Gravitation

Teacher Toolkits, 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.

Concept Builders, Circular Motion and Satellite Motion section, Universal Gravitation

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 Universal Gravitation supports this video and the next one in our Tutorial series.

Minds On Physics, Mssion CG6: Universal Gravitation

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: Gravitational Fields Simulation

Many times the best way to learn is to play. This simulation allows learners to do that - to play with the variables that affect graviational force. They can drag a planet around, change their masses, and observe its effect. A student-friendly activity sheet is available for classroom use.

The Tutorial, Circular and Satellite Motion Chapter: The Apple, the Moon, and the Inverse Square Law

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.
