Energy Skate Park Simulation - Conservation of Free energy

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

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

conservation of energy tells united states of america that nosotros tin never create or destroy energy, but we can modify its form.

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

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

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

simulation volition open in a moment.

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

right side of the screen. Get familiar with the 'Reset' buttons on the right and how to change 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 accept at the 2 meter mark?

The energy the skater has is potential energy.

two. How high does the skater become on the other end of the ramp?

The skater got 2meters.

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

to question 2 at this point.
