Day 137: Hot Wheels Challenge

Energy-Momentum Energy-Projectile Motion practicum for college-prep students who have finished their assessments: Predict where the Hot Wheels car will land if it is released from the top of the ramp and rolls off the edge of the table.

    Whoops. That was supposed to say "Energy-Projectile Motion." And for now, we didn’t take friction into consideration. I’ve seen labs where kids determine the frictional energy loss per unit length of track first, then go on to do the energy-projectile prediction and supposedly get better results.Since the cars fall short due to friction, I let them use a BeeSpe photogate timer to get the actual speed of the car as it leaves the table. They then do a quick recalculation and I let them test again.
