Push the cart from the lower end of the track up the incline.Release from the elevated end of the track and let it accelerate to the lower end.You have two options for collecting velocity data from the cart: Record each value of h chosen, and then obtain a graph of velocity versus time for that value.ģ. Choose at least five values of height h, to vary over the range 1-8 degrees.Ģ. The low end of the track should have a magnetic bumper installed on it (magnets face upward along the track). Connect a motion sensor to the ULI and mount it on the elevated end of the track. Measure h by measuring the difference in the two heights of your two points.Ĥ.You can choose any two points along the track to serve as your L, but they must be the same two points for all your runs!.Choose a value of h so that the angle of inclination stays less than about 8 degrees. Elevate one end of the track slightly using the vertical rod. Attach the ramp clamp to the lab stand and attach one end of the ramp.ģ. ![]() Connect the ULI to the computer via the USB cable and connect the AC adapter.
