Phet Energy Skatepark

Based on the information provided, could the skater gain more speed?

• No, because he has reached his maximum KE

• Yes, because he has not reached his maximum KE

• No, because he has not reached his maximum PE

• Yes, because he has reached his maximum PE

Do you think the Skater will make it over the first hump?
(No friction on the track)

• No, because his potential energy will be converted to thermal energy

• No, because he doesn’t have enough potential energy

• Yes, because all of his potential energy will be converted to kinetic energy

• Yes, because some of his energy will be potential and some kinetic
