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.

(Centripetal acceleration points toward the center of the circular path and changes the direction of velocity; for uniform circular motion it does not change the object’s speed.)
