Sometimes it isn't enough to just read about it. You have to interact with it!
And that's exactly what you
do when you use one of The Physics Classroom's Interactives. We would like to suggest that you
combine the reading of this page with the use of our It's All Uphill Interactive. You can find it in the
Physics Interactives section of our website. The It's All Uphill Interactive allows a learner to explore the
effect of an incline angle upon the force and the work done in pulling a cart up a hill at a constant speed.
