A:### Quick Answer

**Angular motion is the motion of a body about a fixed point.** The motion of pendulums and planets are examples of angular motion. Angular motion can also be used to describe the angle made during the motion of a body about a fixed axis.

Motion is the change in position of an object from its initial position to its final position with respect to time. Angular displacement or rotational displacement is the angle passed over at the point by a line drawn from the given axis of rotation, and it is expressed in radians. Angular motion with constant acceleration occurs in a machine with spinning parts.

- Q:
## What is a lever called when it rotates around a fixed point?

A:A lever, by definition, is a rigid bar that rotates around a fixed point. The fixed point is called a fulcrum. A lever is a simple machine, and its function is to use a force, called effort, to move a weight, called a load or resistance.

## How do you find angular velocity?

A:Find the angular displacement using the formula ? = d?/dt, ?/t or v/r. "?" represents the angular velocity, "d?" represents change in angular displacement, "dt" stands for change in time,"?" represents displacement and "t" represents time taken. "V" is the linear velocity, and "r" is the radius of circular path.

## What are angular acceleration units?

A:

Full Answer >**The units for angular acceleration are radians per second squared (rads/sec^2).**Angular acceleration is the change in angular velocity during a given time interval, where radians is the measure for velocity and seconds are the units of time.Filed Under: - Q:
## What is the angular acceleration formula?

A:While there are several formulas for angular acceleration, the basic equation is the change in angular velocity divided by the change in time. This relationship is shown in the following equation: (Av2 - Av1)/(T2 - T1).
