Energy Skate Park

Questions 1-6 go with the reading passage ("passage 2" at the top).

Potential energy is (a)   .

Kinetic energy is (a)   .

In the half-pipe, when is potential energy the highest?

(top or bottom)

(a)  

In the half-pipe, when is kinetic energy the highest?

(top or bottom)

(a)  

What force acts against the skateboard to slow skaters down?

(a)  

A half-pipe at a skate park demonstrates the law of conservation because energy (a)   but is never created or destroyed.

Click "Intro" to begin. As the skate park opens, observe the movements of the skater in the half pipe WITHOUT CHANGING ANY OPTIONS. Check the "grid", "bar graph", and "pie chart" boxes.

For this question, there is no friction.

The skater reaches the (a)   height on both sides of the track.

(same or different)

On the visual aids, ​ (a)   represents potential energy, ​ (b)   represents kinetic energy, and ​ (c)   represents mechanical energy (or the total amount of energy).

Explore the U-shaped track and the W-shaped track and observe the energy as the skater goes back and forth.

When does the skater have the highest amount of potential energy?​ (a)  

When does the skater have the lowest amount of potential energy?​ (b)  

When does the skater have the highest amount of kinetic energy?​ ​ (a)  

When does the skater have the lowest amount of kinetic energy?​ ​ (b)
