Which form of energy comes from the nucleus of an atom?
Give an example of chemical energy
Give an example of sound energy
Give an example of light/radiant energy
What forces are acting on you right now?
Why, when you drop the skater off next to the ramp, does the Kinetic energy turn to thermal? Feel free to play with the simulation, you can find it here. https://phet.colorado.edu/sims/html/energy-skate-park/latest/energy-skate-park_all.html
Which is a better way to show that there is only specific amount of energy, and it is always in one form or another?
If the skater's speed is 0, what would you expect the bar and chart graph to look like?
When the board is stuck to the track, why does the skater who started lower than the top of the loop go higher than the skater who is not stuck to the track?
Why do you have to start the skater above the level of the track in order to finish the loop de loop?
Why do you think making the loop skinnier helps the skater stay on the track even though she has the same amount of total energy?
How does changing the gravity (from earth, to the moon, to Jupiter) change the simulation?
Why does changing the gravity change the simulation?
Play with the "w" shaped track. Since the track is asymmetrical, how do you expect the skater to not make it up to the same height as before? why or why not?
What do you observe when the skater is on the "w" track?
Click the path button and watch the dots show up as the skater goes up and down the ramp. are the spaces between the dots on the path spaced evenly or not evenly?
drop the skater well above the top of the ramp. watch the path dots. record some observations here.
Does changing the skater change anything about the speed or energy of the skater? Should it?
8th graders and honors only, everyone else can go! Have you ever watched a skater who seemed to never push off the ground, but still end up higher than when he started?
When the skater in the video pumped when he was on flat ground, what was the effect?
Why was it different when he was on a slope?
Explain why you want to pump at the bottom of the curve and not at the top when you are coming down?
Does the center of mass argument work for going up a hill?
What aspects of good scientific method did the skater display in his demonstration at the end?
