Part 1: Click on the intro tab and play around with the simulation.
What happens when you make friction and gravity zero?

____________________
Put friction and gravity to the middle. Now change the skaters mass. What happens as you
increase the mass?
__________________________________________________________________________________________________
__________________________________________________________________________________________________
____________________
Click on the energy graph. What happens to kinetic and potential energy as you release the
skater?
__________________________________________________________________________________________________
__________
What energy is gradually increasing and eventually causes the skater to slowly come to a
stop?

__________
Part 2: Click on the measure tab. You should see a purple device to measure energy.
Put the skater on the track and use the measuring tool to measure kinetic and (gravitational)
potential energy.
What happens to the kinetic energy as you go along the track?
__________________________________________________________________________________________________
__________
What happens to the gravitational potential energy as you go along the track?
__________________________________________________________________________________________________
__________
Click on pie chart at the top. What is happening to the kinetic and (gravitational) potential
energy on the chart as the skater goes down the track.

______________________________
Repeat it again with a different track or different mass/gravity/friction. Did anything change?

Part 3: Click on the playground tab. Create your own track. Try to create a loop for
your skater to go upside down in. What happens to energy while they are in the loop?
