Its linear acceleration a is its rate of change in linear velocity v, were v is the velocity vector tangent to the circle at the point where the mass is. The relation between the two is that linear acceleration equals radius of path multiplied by angular acceleration. How does angular acceleration relate to linear acceleration? Physics Rotational Motion Rotational Dynamics. Trevor Ryan. Sep 2,

Angular motion variables. Relating angular and regular motion variables. Practice: Angular and tangential acceleration. Introduction to rotational motion review.

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:.

I am wondering, when solving rigid body exercises, how can I express the relationship between linear and angular acceleration for a general case? And what about the case of a yoyo? As you stated, the angular acceleration, tangential linear acceleration and distance between the reference point and the object are related using the following formula:.

According to the sign convention, the counter clockwise direction is considered as positive direction and clockwise direction as negative. Figure 1. This figure shows uniform circular motion and some of its defined quantities. The faster the change occurs, the greater the angular acceleration. In equation form, angular acceleration is expressed as follows:. Suppose a teenager puts her bicycle on its back and starts the rear wheel spinning from rest to a final angular velocity of rpm in 5. In this part, we know the angular acceleration and the initial angular velocity.
