Notes - on Procedure, Experiment 2:
Kinematics on an Inclined Plane
f
If the ramp tends to wobble upon ball release, stabilize
it by holding on to the upper end of the ramp.
Notes - on Analysis
Here are the results for the measurement of the fnal ve-
locities of the ball down the incline plane.
Table 2.1
Δd = 1.6 cm
Here is a plot of describing the linear relationship be-
tween the squared of the final velocity and distance trav-
elled by the ball down the incline plane. The mathematical relationship being depicted by the plot is

Answers - to Questions
c
Yes. a = 0.43 m/s 2
d
. This is because time can be accurately
measured. This is not true for velocity and
accceleration for complex motions.
