> The resultant force on an object moving in a circular motion at a constant speed is referred to as the centripetal force as it acts in the same direction as the centripetal acceleration.
Examples of centripetal force
> An object spinning on a bit of string - Tension in the string
> A satellite orbiting the earth - Gravity pulling the satellite towards the earth
> For an object moving at a constant speed, v in a circular motion of radius, r
Centripetal force, f = mv² / r
Centripetal force, f = mω²r
