Energy Skate Park Lab Part 1

Read and follow the instructions. Then select everything you did below.

First, Click Intro to enter the Intro Energy Skate Park.

On the left side, click the GREEN box to expand the Energy Table.

On the right side, check the boxes for Speed, Pie Chart, and Path, then select the skateboarder you will use for this assignment.

• I entered the Intro Energy skate Park and expanded the Energy Table

• I checked the Speed, Pie Chart and Path boxes.

• I selected my preferred skateboarder

• I unchecked the "stick to track" option without being told to.

Match the colors with the energy they represent in the Energy Skate Park.

• Potential Energy

• Green

• Kinetic Energy

• Blue

• Thermal Energy

• Orange

Click slow at the bottom of the screen.

Place the skater at the top, like in the picture.

Watch the bar graph as the skater moves.

Where is the potential energy the highest?

Potential Energy is based on ​ (a)   . The ​ (b)   the skateboarder goes, the more ​ (c)   potential energy the skateboarder has. In the Energy Skate Park, Potential energy is represented with the color​ (d)  

• position or height
• higher
• gravitational
• blue
• green
• orange
• motion or velocity
• faster
• kinetic

With slow mode enabled (bottom of screen), place the skater as shown in the image.

Make sure your speed is still visible!!

Where will the speed be the highest?

Where is the Kinetic Energy of the skateboarder the highest?

Kinetic Energy of an object is based on ​ (a)   . The ​ (b)   the skateboarder goes, the more ​​ (c)   kinetic energy the skateboarder has. In the Energy Skate Park, Kinetic energy is represented with the color​ ​ (d)   .

• motion or velocity
• faster
• mechanical
• green
• position or height
• slower
• thermal
• blue

Place the skateboarder somewhere in the upper half of the right side and release them. Observe the pie chart. What happens when the skateboarder reaches the top of either side? bottom?

• The skateboarder's pie chart is completely blue at the bottom of the path

• The skateboarder's pie chart is completely blue where they change direction the top.

• The skateboarder's pie chart is completely green where they change direction the top.

• The skateboarder's pie chart is completely green at the bottom of the path

I observe that the dots appearing along the path​ (a)   as the skateboarder goes down the ramp. The dots (b)   as the skateboard goes up the track.

• get further apart
• get closer together
• stay the same distance from each other

Watch the bar graph on the left and increase the mass of your skateboarder to 100 kg using the slider on the right, then click restart skater. How did the graph change?

The maximum value of Kinetic energy ​ (a)   .

The maximum value of Potential Energy ​ (b)   .

The total energy stayed constant and ​ (c)   .

• increased
• stayed the same
• decreased
