Physics 12 Question!

Circular motion!



A car travels around the same circular track at different velocities. which graph best shows the relationship between its centripetal acceleration, ac, and its velocity, v?

Answer 1

ac or a= V^2/r

a= acceleration

v= velocity

r= radius

This is the formula, but I do not understand which graph it is?

Answer 2

since it has different velocities
and a=v^2/r
even acc is increasing
so it has an increasing slope..

Answer 3

I do not understand why ac is increasing, and why it has an increasing slope?


Could you please explain more?
