If you increase the radius of circular motion while keeping the angular velocity constant, the centripetal acceleration will decrease.

Here's why:

* Centripetal acceleration formula: a = v²/r

* 'a' is centripetal acceleration

* 'v' is the linear velocity

* 'r' is the radius of the circular path

* Relationship between linear and angular velocity: v = ωr

* 'ω' is the angular velocity (radians per second)

Combining these equations:

* a = (ωr)² / r

* a = ω²r

This shows that centripetal acceleration is directly proportional to the radius when angular velocity is constant.

Therefore, if you increase the radius, the centripetal acceleration decreases.
