# Relation between linear acceleration and angular acceleration in vector form

## The Universal Portal for Education Linear position, velocity, and acceleration have their the axis of rotation is related to the angular velocity by the relation vt = r?. The centripetal acceleration vector points inward from the.

In this section, we relate each of the rotational variables to the translational variables defined in Motion Along a Straight Line and Motion in Two and Three Dimensions. This will complete our ability to describe rigid-body rotations. In Rotational Variables , we introduced angular variables. If we compare the rotational definitions with the definitions of linear kinematic variables from Motion Along a Straight Line and Motion in Two and Three Dimensions , we find that there is a mapping of the linear variables to the rotational ones. Linear position, velocity, and acceleration have their rotational counterparts, as we can see when we write them side by side:.
