Angular Motion - Power and Torque - Angular velocity and acceleration vs.Acceleration Units Converter - Converting between units of acceleration.Mechanics - Forces, acceleration, displacement, vectors, motion, momentum, energy of objects and more.Dynamics - Motion - velocity and acceleration, forces and torque.I = Moment of inertia (lb m ft 2, kg m 2)

= 120 degrees/s 2 Angular Moment - or TorqueĪngular moment or torque can be expressed as: The deceleration of the flywheel can be calculated as Ω = (ω o 2 + 2 α θ) 1/2 Angular AccelerationĪngular acceleration can be expressed as:ĭt = change in time (s) Example - Flywheel Decelerationīy Geni (Photo by User:geni), via Wikimedia CommonsĪ flywheel is slowed down from 2000 rpm ( revolutions/min) to 1800 rpm in 10 s. Α = angular acceleration or deceleration (rad/s 2) Angular DisplacementĪngular distance can be expressed as (angular acceleration is constant):

Ω o = angular velocity at time zero ( rad/s) The tangential velocity of the tire can be calculated asĪngular velocity can also be expressed as (angular acceleration = constant): R = distance from center to the point (m, ft, in) Example - Tangential Velocity of a Bicycle TireĪ 26 inches bicycle wheel rotates with an angular velocity of π radians/s (0.5 turn per second). V = tangential velocity (m/s, ft/s, in/s) The tangential velocity of a point in angular velocity - in metric or imperial units like m/s or ft/s - can be calculated as Linear Motion Calculators Average velocityĪngular velocity can be expressed as (angular velocity = constant): The acceleration can be calculated by transforming (1b) to = 20.5 km/h Example - Acceleration of a CarĪ car accelerates from 0 km/h to 100 km/h in 10 seconds. If a marathon - 42195 m - is run in amazing 2:03:23 (7403 seconds) (Wilson Kipsang, Kenya - SeptemBerlin Marathon) - the average speed can be calculated Velocity can be expressed as (velocity is variable) Linear distance can be expressed as (if acceleration is constant):Ĭombining 1b and 1c to express the final velocity V 0 = initial linear velocity (m/s, ft/s) If acceleration is constant then velocity can be expressed as: we use velocity and speed interchangeable - but be aware that speed is a measure of how fast or slow a distance is covered, the rate at which distance is covered - velocity is a vector, specifying how fast or slow a distance is covered and the direction.distance is the length of the path a body follows in moving from one point to another - displacement is the straight line distance between the initial and final positions of the body.Average velocity/speed of a moving object can be calculated as
