Click the pause button first. Place the skater on the ramp at a height of 4 meters. Look at the bar graph. What type of energy does the skater start with before it starts moving?

HS-PS3-A-2

Required

1

The skater should still be on the ramp at 4 meters. Now click play. Watch the bar graphs. What happens to the potential energy as the skater moves downhill (increase, decrease, stays the same)?

HS-PS3-B-3

Required

1

Watch the bar graphs. What type of energy does the skater gain as it moves down the hill?

HS-PS3-A-2

Required

1

Look at the bar graphs. At what location does the skater have the most Potential Energy (top, middle, or bottom)?

HS-PS3-A-2

Required

1

Look at the bar graphs. At what location does the skater have the least Potential Energy (top, middle, or bottom)?

HS-PS3-A-2

Required

1

At what location does the skater have the most Kinetic Energy (top, middle, or bottom)?

HS-PS3-A-2

Required

At what location does the skater have the least Kinetic Energy (top, middle, or bottom)?

HS-PS3-A-2

Change the start height of the skater and watch how it affects how high the skater goes on the other side.

In other words, start the skater at 2 meters and watch how high it goes on the other side.
Then start the skater at 4 meters and watch how high it goes on the other side.
Then start the skater at 6 meters and watch how high it goes on the other side.

Is the ending height always the same, more than, or less than the starting height?

Required

1

Compare what happens to both types of energy as the skater goes down the hill and up the hill.

Even though the type of energy changes, the total mechanical energy of the system ____.
