Starter : At what points on the path of a
swinging child is her speed a maximum?
A minimum? How does this relate to the
height of the child above the ground?
Open the “ Energy Skate Park Basics” at the phet site.
In the “ Introduction” tab, pick the first track (U shaped.)
Check “ bar graph” , “speed”, “grid” and “slow motion”.
Place the skater at 4m above the ground on the track and release.
Read and record the velocity at the following heights.
Each increment on the speed dial is 1.0m/s
Describe how the kinetic energy and the potential energy are
related by observing the bar graph.
a. What can you tell about the sum of KE and PE?
b. When the KE is a maximum, what is the PE?
c. How is the KE related to the velocity?
d. How is the PE related to the height?
2. At what height are the potential energy and the kinetic energy equal?
How are h and v related? Are they directly proportional?
Plot v2 vs. h and do a best fit for the graph. What does this tell you about
the relationship between h and v?
