AssessmentQuestion 1(1 point)SavedIf the skater in the picture is starting at rest willhemake it over the first hump?Question 1 options:A)No – He doesn’t have enough PEB)Yes, friction will turn into thermal energy which will boost his speedC)Not enough informationD)Yes, but friction but will slow him downQuestion 2(1 point)Gotohttps://phet.colorado.edu/en/simulation/energy-skate-parkand open the simulation.On the right click the button that says “Show Path”. Let it make purple dots marking the position of the skater at regular time intervals.Turn “Path” off when the skater has gone from one side of the ramp to the other.What happens with the dotsat the lowest part of the track.Question 2 options:A)They get closer togethershowing the the skater is speeding upB)They getcloser togethershowing the the skater is slowing downC)They get farther apart showing the the skater is speeding upD)They get farther apart showing the the skater isslowing downQuestion 3(1 point)SavedHit the “pause” button and click & drag the blue circle at the end of the track opposite the skater until its at half the original height. (if the skater is paused on the left, lower the right end of the track.)Hit play. What happens when the skater gets to the lowered end of the track?Question 3 options:A)Not enough information.B)Because the end is now lower the PE is lower. With less energy he doesn’t make it to the end.C)He stops abruptly at the lowered end.D)Because the end is now lower he still has KE left over and flies off the end.Question 4(1 point)SavedHit the “Reset” button at the top and confirm. The skater and track shape and everything should return to original configuration.Click the measuring tape checkbox at top right, and move the tape such that the tape marks the maximum height of the skater.Click the “Choose Skater” button at the top right of the animation and replace the skater with the 5 kg red ball.What happens to the max height of the red ball versus the max height of the skater.Question 4 options:A)The red ball goes the same height as the skaterB)Not enough information.C)The skatergoeshigher thanas the red ball.D)The red ball goes higher thanas the skater.Question 5(1 point)SavedNon-Conservative ForcesHit the “Reset” button at the top and confirm. The skater and track shape and everything should return to original configuration.Hit the “Energy vs Position” button. The green graph shows KE rising and fallingas PE falls and rises. The yellow line at the top is the sum of KE & PE – showing that energy is conserved. The red graph is thermal energy or heat from friction. Right now the friction is zero.Click the “Track Friction” button. Drag the slider a little to the right to cause friction to increase.Watch the skater AND the graph! What happens?Question 5 options:A)I don’t really care what happens!B)The KE and PE energy both increase as thermal energy increasesin order to conserve energy.C)The friction “steals” some of the KE, so the skater doesn’t go as high. The”stolen” energy becomes thermal energy/heat.D)Everything stays the same as it was before there was friction.
