Rotation Flashcards
Angular Velocity
The rate of change of the angular position of a rotating body.
Angular Acceleration
The rate at which the rotation of a rotating body changes
Angular Displacement
The angle through which something has been rotated about an axis
Moment of Inertia
A quantity expressing a body;s tendency to resist angular acceleration
Torque
The tendency of force to cause or change the rotational motion of a body.
Radian
A unit of angle, equal to an angle at the center of a circle whose arc is equal in length to the radius
Lever Arm
the Perpendicular distance from the axis of rotation to the line of action of the force
Rotational Energy
the kinetic energy of an object due to its rotation
angular momentum
the quantity of rotation of a body, which is the product of its momentum of inertia and its angular velocity
right hand rule
a convention used to relate the direction of the rotation of an object to its vector representation
frequency
the rate at which something occurs or is repeated over a particular period of time or in a given sample
Period
the time need for one complete cycle of a repeated motion
