# Simple Harmonic Motion with Motion Graphs

### Summary

Pick a Video:
Tools:

A low-friction glider moves on an air track. Springs apply forces to the glider that cause simple harmonic motion. The motion graphs above are not animated, nor computer generated. They are recordings of data collected from a Vernier ultrasonic motion detector.

Students use this video to observe the relationship between the position, velocity, and acceleration of an object moving in simple harmonic motion.

### Instructor Note

When teaching with this video, direct students to the student video library, which provides student access to all videos without links to instructor materials and solutions.

Simple Harmonic Motion with graphs in DMV Player

## Teaching Materials

This video can be used as a conceptual introduction to the kinematics of simple harmonic motion. Students can observe, compare, and contrast the position, velocity and acceleration of the glider at different times. Here are some example questions to guide students:

• At what location is the velocity the at a maximum?
• At what location is the acceleration at a maximum?
• Sometimes people claim it is impossible for an object which is not moving to be accelerating. They say that if v=0, then it must be true that a=0. Use this example to respond to this claim.

The Direct Measurement Video project has become Pivot Interactives, an educational resources company run by the same dedicated physics teachers who've been developing DMVs since in 2010. We're more committed than ever to bringing powerful teaching tools to students and instructors everywhere.

Our free service on the SERC website will come to an end on June 1, 2018. We invite you to subscribe to Pivot Interactives where you'll find new functionalities. For example, the new learning platform includes integrated, modifiable instructions, data tables with calculated columns, graphing with linear fit, and enhanced grading tools, ...not to mention a boatload of really cool new videos. This integrated platform is far more powerful and effective than videos alone. We hope that if you've had success with DMVs you'll try a free 30-day trial of the new videos and easy-to-use teacher tools.

• Access to hundreds of videos with interactive tools, which can be used on their own or paired with the integrated activities
• Over 150 new classroom-ready activities, which can be edited, modified, and saved in your account.
• Integrated components: videos and tools, instructions, graphing, and grading
• Enhanced students' scientific reasoning
• A free, 30-day trial allows access to the entire Pivot platform without restrictions

What teachers say about Pivot Interactives:

"The new Pivot Interactives platform is an impressive leap over just having the videos only. I'll use the new PI platform in my AP Physics class more than I would use the original Direct Measurement Videos alone. " -Alan Calac, Abraham Lincoln High School. San Francisco, California

Pivot Interactives is a game changer. The price is reasonable and you can build a physics curriculum around them. The new tools in Pivot Interactives are wonderful and give more independence to the students. -Tim Taylor, Stratton Mountain School; Stratton, Vermont

"I've made it my official teaching goal this year to replace as many textbook-style homework problems as possible with Pivot exercises. Everything I see on the site is something that makes me say 'wow'. I highly recommend." -Greg Jacobs Woodberry Forest School, Woodberry Forest, VA 22989

My thoughts on Pivot Interactives in perpetuity: Take my money! -Trevor Register, Cherokee County GA
