What effect does friction have on a roller coaster

Hello There!

Let's first talk about "What Is Friction"

Friction is a force that pulls when two object touch each-other. Friction happens because the molecules on one surface interlock with the molecules on another surface.

Now, let's get back to our original question "What Effect Does Friction Have On A Roller Coaster"

On a roller coaster, friction is a force that opposes motion and significantly slows the cars as they move on the track.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
