Doing endless inclined plane problems on paper can get old really fast, so why not create a real-life version where students are responsible for taking measurements and using them to calculate actual information?
This lab doesn’t require a lot of fancy materials either. All you need is some sort of ramp (like a 2 x 4), a cart or buggy, some meter sticks, and a spring scale. Prop the ramp up on the chalkboard ledge, a chair, or a couple of books and you’re ready to go. Students should be able to calculate Fg, Fnet F//, Fnormal, Ffriction,θ, μ, acceleration, and velocity.
