Free energy Skate Park Simulation - Conservation of Energy

Purpose: When Tony Hawk wants to launch himself equally high equally possible off the half-pipe, how does he

achieve this? The skate park is an fantabulous example of the conservation of energy. The law of

conservation of energy tells us that we can never create or destroy energy, only we can change its form.

In this lab, you lot will analyze energy transfer between gravitational potential energy, kinetic energy, and

energy lost due to collisions or friction (thermal energy) as a skate boarder rides along a runway.

Instructions: Go to the web address written below, and click the "Run Now" button ( ). The

simulation will open in a moment.

Take some fourth dimension to play with the simulation. Turn on the 'Bar Graph,' 'Grid,' and 'Speed' options on the

right side of the screen. Become familiar with the 'Reset' buttons on the correct and how to modify the

speed of the simulation with the buttons on the lesser.

Part I: Introduction ( Turn on the 'Bar Graph,' 'Filigree,' and 'Speed' options.)

Set the skater 2 meters above the ground on the ramp and release him.

1. What type of energy does the skater have at the 2 meter mark?

The energy the skater has is potential energy.

2. How high does the skater get on the other end of the ramp?

The skater got 2meters.

3. Explain, in terms of the conservation of energy, why the skater will never go college than your answer

to question 2 at this point.
