Energy Skate Park activity: Calculations with Conservation of Mechanical Energy using time graphs https://phet.colorado.edu/en/simulation/energy-skate-park Energy Skate Park Estimate a location for the Skater on a track. Calculate the speed or height of the Skater Predict energy distribution for tracks with and without friction. Without using the simulation, predict the answers to the PR 5 following questions. I DOWNLOAD EMBED Directions: 1. This graph below was made with the 50 kg Skater riding on the track shown. The Skater was initially positioned on the top left of the track. Without using the simulation, provide a prediction to the following questions Energy Graph Position Time Speed 2508 Stick to Track Kinetic . Energy (3) XXXXXXXXX VW Them .

Change the Mass of the Skater to 100 kg. a) Predict how you think the 100 kg Skater's position, speed and energy compares to the 50 kg Skater. b) Using the simulation, discuss how the 100 kg Skater's position, speed and energy compare to the 50 kg Skater. Provide a screenshot of the Skater and graph. 3. Move the Friction slider to 'Lots' . a) Predict how you think the 100 kg Skater's position, speed and energy compares to the 50 kg Skater. b) Using the simulation, discuss how the 100 kg Skater's position, speed and energy compare to the 50 kg Skater. Provide a screenshot of the Skater and graph
