The equations of motion can be applied to angular motion as well as linear motion, as long as all tangential/linear quantities are substituted for their angular counterparts.
Time (doesn't change!)
You can convert between linear and angular motion by multiplying or dividing the radius as a factor. To think about this intuitively, this is because , and if the circumference is directly proportional to the radius, then velocity, acceleration, etc. must be directly proportional to the radius as well.
