Rotational frequency - Wikipedia
WebRotational frequency, also known as rotational speed or rate of rotation (symbols ν, lowercase Greek nu, and also n ), is the frequency of rotation of an object around an axis . Its SI unit is the reciprocal seconds (s −1 ); other common units of measurement include the hertz (Hz), cycles per second (cps), and revolutions per minute (rpm).
Angular velocity - Wikipedia
WebWith orbital radius 42,000 km from the Earth's center, the satellite's tangential speed through space is thus v = 42,000 km × 0.26/h ≈ 11,000 km/h. The angular velocity is positive since the satellite travels prograde with the Earth's rotation (the same direction as the rotation of Earth).
Revolutions per minute - Wikipedia
WebRevolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or r⋅min −1) is a unit of rotational speed (or rotational frequency) for rotating machines. One revolution per minute is equivalent to 1 / 60 hertz.
Rotation - Wikipedia
WebRotation or rotational motion is the circular movement of an object around a central line, known as axis of rotation. A plane figure can rotate in either a clockwise or counterclockwise sense around a perpendicular axis intersecting anywhere inside or outside the figure at a center of rotation.
Earth's rotation - Wikipedia
WebThe angular speed of Earth's rotation in inertial space is (7.292 115 0 ± 0.000 000 1) × 10 ^ −5 radians per SI second. Multiplying by (180°/π radians) × (86,400 seconds/day) yields 360.985 6 °/day, indicating that Earth rotates more than 360 degrees relative to the fixed stars in one solar day.
Torque - Wikipedia
WebFor example, if rotational speed (unit: revolution per minute or second) is used in place of angular speed (unit: radian per second), we must multiply by 2 π radians per revolution. In the following formulas, P is power, τ is torque, and ν ( Greek letter nu ) is rotational speed.
Angular frequency - Simple English Wikipedia, the free …
WebIn physics, angular frequency, ω, (also called the angular speed, radial frequency, and radian frequency) is a measure of rotation rate. A high rate of angular frequency means something is turning very fast. The angular frequency is the magnitude of the vector quantity angular velocity which is also known as angular frequency vector .

WebAngle of Rotation. What exactly do we mean by circular motion or rotation? Rotational motion is the circular motion of an object about an axis of rotation. We will discuss specifically circular motion and spin. Circular motion …
Rotational Speed and Velocity - Physics Bootcamp
WebThe direction of angular velocity vector is the direction of rotation axis and the magnitude is the rate at which the body is rotating. Therefore, if the body is rotating at speed 10 rad/sec 10 rad/sec about an axis in the direction ^u, u ^, we will write this as. →ω = (10 rad/sec)^u. ω → = ( 10 rad/sec) u ^. Figure 9.3.9.
