Question

Which is a characteristic of centripetal acceleration?

It is directed outward from the center of a circle.
It is directed inward, toward the center of a circle.
It results in an object moving faster.
It results in an object moving slower.
​

Answer 1

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

Answer 2

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

Step-by-step 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)=(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.
