Question

When a road curves, (let's say to the right) why does it slope towards the right direction?

Answer 1

... I'm not a Physics master.

Answer 2

there has to be a centripetal force for things to travel curved paths. otherwise they travel in a straight line... If you bank a curved road, then you are using the Normal force to produce some or all of the required centripetal force...

Answer 3

If you didn't bank the roadway, you'd be relying entirely on the friction between the tires and the road to provide a centripetal force... and it's not a very predictable force.
it changes with road conditions, tire conditions, etc.

Answer 4

Oh yes, gotcha.

Answer 5

Thank you.

Answer 6

sure:)
