Do you think the skater will make it over the first hump, based on the PhET lab? (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.

Why do objects at high elevations have more potential energy than objects at low elevations?
Because the thinner air at higher elevations means objects have a greater potential to move very fast
Because objects at high elevations are closer to the sun, which is the source of all energy on earth
Because objects at high elevations tend to move slower than objects at low elevations
Because gravity gives objects at high elevations the potential to fall much further
Why does the nickel have double the kinetic energy compared to the penny?
The mass of the nickel is double the amount of the penny.
The speed of the nickel is double the amount of the penny.
The nickel does not have double the kinetic energy of the penny as they are equal.
The nickel is shinier than the penny so its kinetic energy is higher.
