í Measuring Data
u Prepare the Distance Measurement Setup. Immediately after starting the measurement
operation, let the cart go.
u When the cart reaches the desk, stop it.
u Graph the data on the calculator, observe its characteristics, and compare it with
theoretical expectations.
u Change the angle of the ramp 10 degrees and then 20 degrees, and measure again.
u Observe how the graph changes as the ramp angle is changed.
í Calculator Operation
u Find the applicable program in the Program Library (P.2-16-1), input it into your calculator,
and then run it.
u Display graphs for the distance traveled, velocity, and acceleration of the cart.

2 Ramp Angle: 15 degrees
3 Ramp Angle: 10 degrees
4 Ramp Angle: 20 degrees
u Study the relationships between the changes of distance traveled, velocity, and
acceleration.
u Consider the reasons why the graphs change as the angle of the ramp is altered.
u Find out how the graph is affected when the mass of the cart is changed by
placing a weight on it.
