In the “Physics 500 Lab” you used constant velocity cars, and you will use them again in this lab! This lab is very simple, but it does give you something measureable and students realize that constant velocity in a circle IS acceleration after completing this lab. Different cars will require different masses in order to keep from tipping over, so encourage students to “play” around first before actually taking any measurements. (Trust me-that’s one instruction they don’t mind following at all!) Analysis #8 does require that students rearrange two equations to show that they really are the same equation, just written in different form. Students who struggle with algebra may have trouble with this question so you may want to do it together as a class.
