Angular Displacement formulas Agha_Haseebullah_Babar

 Angular Displacement :

 When a body moves in a circular path and cover some circumference (distance) is called

angular displacement. S = r

 Its SI unit is degree and “radian”. = s/r = L/L = dimensionless.

 It is vector quantity.

 It is axial vector. Its direction is along the axis.

 Use Right Hand rule,

 Clockwise the angular displacement is inward (negative).

 Anticlockwise Angular displacement is outward (Positive).

 S

 S =r ( radius is constant)

 Circumference of circle = 2 .

 For one complete rotation :

 Circumference of circle S = 2 . ( r is radian)
