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.

Answer:

The correct prediction will be:  

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

The incorrect prediction:

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

The opposing force experienced by any object that is in motion and contact with the surface is called friction (f). It is estimated in Newtons and is calculated by:

[tex]\rm f = \mu \rm N[/tex]

Where N = normal force and [tex]\mu[/tex] = frictional coefficient

  • The correct prediction of the experiment is:

The temperature of the exterior of the ball bearing when rubbed over glass will be minimum.

  • The incorrect prediction of the experiment is:

There will be no friction when the tennis ball is rolled over the linoleum surface as the temperatures do not vary.

The predictions can be explained as:

  • The friction raises the temperature because the intermolecular separation expands so that the work done also raises. In this case, the ball bearing will generate the least temperature.

  • When the tennis ball is rolled over the linoleum surface there will be friction and temperature will also change.

Therefore, friction influences the temperature.
