Question

Explain why a point on the rim of a tire has an acceleration when the tire is on a car that is moving at a constant linear velocity.

Answer 1

Step-by-step explanation:

This is because even with the constant linear velocity, as that point transverses the circle its direction is always changing, and any point on a rotating object possesses centripetal acceleration. hence it is said to be accelerating. Also we can see that from the formula for centripetal acceleration (a) =
`(velocity^(2) )/(radius)` , we can have acceleration with just velocity.
