Work

By Jared Rovny, PhD

Work consists of three important variables: force, cause, and displacement. For a force to do work on an object, there must be some displacement of the object caused by that force. There are many examples of work around us every day—a wagon being pulled by a child, a cart being pushed down a grocery store aisle. This course will provide a broad overview of the concept of work and how to calculate work done on an object.

The material is accessible and very well thought out. Thank you for this resource.

By Kenneth A. on 11. August 2022 for Work

The material is accessible and very well thought out. Thank you for this resource. Imagine if we can have clinical material as well for Years 3, 4, 5, and 6 that would be awesome!

Very simple explanation. Intuitive in nature.

By Aaishah F. on 25. November 2017 for Work: Example 1

Very simply explained. He made a concept that I had been struggling with seem very simple. He explained better than my physics instructor who seems to have given up on teaching a subject that is very interesting.

like it very much

By keabetswe r. on 02. March 2017 for Work: As Change in Energy

every concept is made very simple and as short as possible
