# Angular acceleration (rotational acceleration)

Angular acceleration (rotational acceleration) refers to the change in rotational speed of an object over time. It is usually measured in radians per second squared (rad/s2).

How do you find angular acceleration from rotation? Assuming that you are given the angular velocity of an object (in radians per second), you can find the angular acceleration by taking the derivative of the angular velocity with respect to time. This will give you the change in angular velocity over time, which is the angular acceleration.

##### What is the relation between angular acceleration and acceleration?

There is no definitive answer to this question as it depends on the specific organization or standard you are referring to. However, in general, angular acceleration is a measure of how quickly the angular velocity of an object is changing, while acceleration is a measure of how quickly the velocity of an object is changing. So, while they are related, they are not the same thing.

### How do you convert angular acceleration to RPM?

There are a few different ways to convert angular acceleration to RPM. One way is to use the following formula:

RPM = (60 * angular acceleration) / (2 * pi)

where RPM is the rotations per minute and angular acceleration is in radians per second. Another way to do the conversion is to use a conversion factor of 9.54929658. This means that for every radian per second of angular acceleration, the RPM would be 9.54929658. When the rotation is speeding up the direction of angular acceleration and angular acceleration is? The direction of angular acceleration is always perpendicular to the plane of rotation. In other words, it is the direction of the axis of rotation.

### What is the rotational equivalent to acceleration?

There is no rotational equivalent to acceleration. Acceleration is a vector quantity that measures the rate of change of velocity of an object. It is a measure of the object's acceleration relative to a frame of reference. Velocity is a vector quantity that measures the rate of change of position of an object. It is a measure of the object's velocity relative to a frame of reference.
