Could you share your derivation (that uses energy)? I have worked it out with my students using torque. I have tried the energy approach, but it never seems to work out! Can’t figure out where I’m going wrong! Thanks!

]]>I can’t seem to find the video I thought I watched on your blog, but I thought I watched a car go down a ramp and your students predicted/calculated where it would land. My question is this: When you do this activity in class, do you graph the velocity versus height to derive the relationship between PE and KE? May I get more information about your strategy for this particular activity.

Kind regards,
