what is the difference between in velocity speed and in omega in circular motion?
-when object moves along with straight line or in plane, we use the term velocity for speed, which is defined as rate of change of the displacement with the time. It is denoted by v = d/t.
where d is the displacement in meter and t is the time in sec.
-when object move along with circular path, we use term angular velocity for speed, which is defined as the rate of change of the angular displacement (in radians) with time, and it has units 1/s. It is denoted by w (omega) = theta/Time
where theta is the angular displacement in radian and time in seconds.
