Acceleration towards the centre of the circle
Isn't it centripetal acceleration? I don't think there is an acceleration called centripedal.
If it is centripetal acceleration,
"Centripetal acceleration is the idea that any object moving in a circle will have an acceleration vector pointed towards the center of that circle. Centripetal means towards the center".
You can find out the centripetal acceleration, using this formula,
r= the radius of the circle
I hope this helps
