angular quantity
rotational or circular motion rotate around an axis
Radians or radi
si unit for angular quantity
Relationship between linear and angular
both of them are directly proportional
displacement
s=r0
angular velocity
how fast it rotates
w= 0/t
angular acceleration
how quickly the velocity changes
a=( r )(a)
Linear velocity
V= (r ) (0)
acceleration
a= wf-wi/ t
light 3×10^8 m/s
velocity
displacement per unit per unit of time
v= vf-v1/T
speed
distance travelled per sec(scalar quantity)
