Question

Jules is conducting an experiment involving friction. He is measuring the temperature of various objects and surfaces after quickly rubbing them together.
He is testing a steel ball bearing and a tennis ball on carpet, linoleum flooring, and a glass surface by rubbing the object 20 times in 6 seconds over the surface.
Match the predictions based on the most likely result of his experiment
correct prediction –

incorrect prediction –

The tennis ball over the linoleum floor will have no friction, as the temperatures will not change.

The temperature of the surface of the ball bearing when rubbed over glass will be the least.
