Students were asked to create small roller coasters that contain at least one hill. Students are using marbles and foam tubing so there will be some air resistance and friction. What should the students keep in mind if they want to create a successful roller coaster? [5a, DOK 2]

roller coaster? [5a, DOK 2]
The hill should be taller than the starting height because the marble will pick up
speed on the downward hill and the increased velocity will allow it to travel
higher on the next hill.
The hill should be the exact same height as the starting height because 100% of
the kinetic energy at the bottom of the first hill will be converted back to
potential energy at the top of the next hill.
The hill should be at least a little lower than the starting height because some
of the kinetic energy at the bottom of the first hill will be converted to other
types of energy due to friction so it will not have as much potential energy at
the top of the next hill.
O Without an extra push at the bottom of the first hill, there is no way the car will
make it back up a hill of any height because the marble doesn't have enough
mass or velocity.
