Angular Kinematics

 

Angular Kinematics

-                      Angular distance and displacement

-                      Angular speed, velocity & acceleration

 

Unit of measurement of angular motion         body move around an axis or around of circular path or complete one full circle or around –called – revolution. One revolution divided in smaller division – one revolution is 360⁰, so 1⁰ = Rev

                                                 360⁰

or 4 quadrant each cover 90⁰.

i)                   The biggest unit of angular motion is ( revolution )

ii)                 Smallest unit is the degree

The III^rd unit of arm angle motion is radian  is rearly used in connection with sports btechnique into widly used in engineering and other field.

 

Radian   A radian is the angle subtended at center of the circle by an arch equal in length to the radius.

                                    Circumference = 2 Õ r

                                    Radian = circumference   =    2 Õ r

                                                         Radius                  r

2 Õ  radious must be equal to 360⁰ or 1 revolute.

 

 

1 radian = 57.3

              = 0.16 revolution

A diver performing double twisting, one and a half might, with equal accuracy have been said to execute a “720 twisting  540 or a 4  Õ twisting 3 Õ ”.
