This image of a roller coaster is designed to show important information about potential and kinetic energy. One of these pieces of information is incorrect. Which information is wrong, and why?
*
1 point
The roller coaster would only have kinetic energy at the point labeled “gravitational potential energy and kinetic energy.”
The spot with the “maximum kinetic energy” should be on the lowest point of the roller coaster, at the far left side on the bottom.
The roller coaster would only have potential energy at the point labeled “gravitational potential energy and kinetic energy.”
The information that is incorrect is that "The roller coaster would only have potential energy at the point labeled 'gravitational potential energy and kinetic energy.'" This is incorrect because the roller coaster has potential energy at any point where it is above the ground, not just at that specific point. As the roller coaster climbs up the track, it gains potential energy, which is converted to kinetic energy as it goes back down the track. Therefore, potential energy and kinetic energy are constantly changing throughout the ride.
The incorrect information is:
"The roller coaster would only have potential energy at the point labeled 'gravitational potential energy and kinetic energy.'"
This statement is incorrect because at any point on the roller coaster, it would have both potential energy and kinetic energy. The potential energy would be highest at the highest points of the roller coaster, like at the top of the incline or the peak of a loop, and the kinetic energy would be highest at the lowest points of the roller coaster, like at the bottom of a drop or the bottom of a loop.
