Angular Kinematics and Kinetics Overview

Change in position of an object.

Displacement

Change in position over time interval.

Velocity

Change in velocity over time interval.

Acceleration

Force applied off the center of mass.

Eccentric Force

Rotational force causing angular motion.

Torque

eccentric force has a specified ___

axis of rotation

Line around which an object rotates.

Axis of Rotation

Angle from reference axis to point.

Angular Position

Angular position with a moving reference axis.

Relative Angular Position

Angular position with a fixed reference axis.

Absolute Angular Position

Change in angular position of a segment.

Angular Displacement

Total angle through which an object rotates.

Angular Distance

Scalar rate of angular motion.

Angular Speed

Vector rate of angular motion.

Angular Velocity

Linear velocity of a point on rotating segment.

Tangential Linear Velocity

Maximum rate of motion achieved.

Peak Rate of Motion

Rate of motion at a specific instant.

Instantaneous Speed

Change in angular velocity over time.

Angular Acceleration

Total change in angular velocity over time.

Average Angular Acceleration

Change in angular velocity at a specific moment.

Instantaneous Angular Acceleration

Linear acceleration of a point on rotating segment.

Tangential Linear Acceleration

Acceleration due to change in direction.

Centripetal Acceleration

Resistance to change in motion state.

Inertia

Resistance to change in angular motion.

Rotational Inertia

Moment of inertia about principal rotation axis.

Principal Moment of Inertia

without angular displacement angular velocity is equal to

0

If the object is already rotating with a given velocity, there is no change in that angular velocity without an

externally applied eccentric force.

If angular velocity does not change, then there is no angular ___.

acceleration

When referring to the moment of inertia with respect to one of the principle axes of rotation, the moment of inertia is called the ___

principal moment of inertia.

In angular kinematics there is a specified___

axis of rotation

In angular kinematics an __ force is applied and therefore torque is present

eccentric force

A segment rotating around an axis may have the ability to travel completely in a circle, therefore the number of __ may be specified

number of revolutions
