Activity: Operating the Equipment￿Measuring Data

uPrepare the Distance Measurement Setup. Immediately after starting the measurement operation, let the cart go.

u When the cart reaches the desk, stop it.

uGraph the data on the calculator, observe its characteristics, and compare it with theoretical expectations.

uChange the angle of the ramp 10 degrees and then 20 degrees, and measure again.

uObserve how the graph changes as the ramp angle is changed.

Measurementasurement￿Calculator Operation

uFind the applicable program in the Program Library (P.2-16-1), input it into your calculator, and then run it.

uDisplay graphs for the distance traveled, velocity, and acceleration of the cart.

L(m) : Distance Traveled by Cart

v(m/s) : Cart Velocity

a(m/s2) : Cart Acceleration

t(s) : Cart Travel Time
