Nickalos and Zack are sledding down a snowy hill and notice that their sled heats up as they go faster. Curious, they set up an experiment. They measure their sled’s speed and the surface temperature of the sled at different points on the hill. They record their data on a table: Relationship Between Speed, Kinetic Energy, and Sled Surface Temperature.

• GOT IT!

• I don't get it.
