How does an object change its orientation?

An object translates , or changes location, from one point to another. And an object rotates , or changes its orientation . In general, the motion of an object involves both translation in all three directions and rotation about three principle axes . On this page we will only consider the rotation of a solid object about one axis.

Orientation

The concept of orientation describes how a body is currently rotated relative to a set neutral orientation. Along with the position, it is necessary to fully define the location of a rigid body.

Angular Displacement

The angular displacement is simply the change in orientation between two points in time.

Angular Velocity

The angular velocity of a rigid body is defined as the rate of change of orientation over the rate of change of time.

Angular Acceleration

Finally, the angular acceleration is defined as the rate of change of the angular velocity over time. Since the angular velocity itself is the rate of change of the orientation over time, the angular acceleration is the double derivative of the orientation with respect to time.

What is a Radian?

An angular displacement defines how far an object has rotated. We measure angular displacement in radians. A radian is a measure of an Angle. It is defined by a rotating object moving a circular distance equal to the radius. The simulation to the left illustrates how we get the measure of one radian.

Arc Length

In physics we use arc length to measure the distance an object travels while rotating around a fixed axis. If we use radians to measure degrees then the distance traveled in meters is equal to the angular displacement in radians times the radius. .

Converting Radians Revolutions and Degrees

is the circumference of a circle and a radian is defined by an object traveling the distance of one radius around a circular path. That means there are radians in one complete revolution. Converting radians degrees and revolutions is like any other unit conversion.

Rolling Without Slipping

One last important note before you take the quiz. If an object is rolling without slipping, like a bicycle with its wheel rolling on the ground, then the linear distance travelled by the bicycle is the same as the arc length for the wheel. In cases like this we can say that .
