Question

Which is a characteristic of centripetal acceleration?

Answer 1

Answer:

It is directed inward, toward the center of a circle.

Answer 2

Answer:

It is directed inward, toward the center of a circle.

Explanation:

Centripetal acceleration is the acceleration resulting from a movement along a circular path.

This acceleration is always directed towards the center of the circle and is defined as follows:

$a_{c}=\frac{v^2}{r}$

where $v$ is the tangential velocity of the object in the circular path, and $r$ is the radius of the circle.

So the answer is: It is directed inward, toward the center of a circle.
