PHet Skate Park Pre-Lesson

 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

 Do you think the Skater will make it over the first hump  if there where a lot of 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

 Do you think the Skater will make it over the first hump If there is a lot of FRICTION on the track?

• No, because his potential energy will be converted to thermal energy
• Yes, if not too much energy is converted to thermal
• 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

In the next moment, the KE piece of the pie gets larger, then

• The Skater is going up hill (left)
• The Skater is going down hill (right)
• There is no way to tell

In the next moment, the KE piece of the pie gets larger, then

• The PE part stays the same
• The PE part gets larger too
• The PE part gets smaller
• There is no way to tell

In the next moment, the KE piece of the pie gets larger, then

• The Skater will be going faster
• The Skater will be going slower
• There is no way to tell
