If you’ve ever walked up a ramp, then you’re familiar with one of the simple machines that people have used for thousands of years — the inclined plane! In this BrainPOP movie, Tim and Moby explain the physics behind how inclined planes work. You’ll discover why you can see them in lots of places — in ramps, doorstops, axles, and even in screws! And you’ll learn how inclined planes decrease the amount of effort you need to expend to move something. It’s a simple physical concept, but it’s an important one too — watch our movie and learn all about it!
