00:00:00Hello students.
00:00:22Today we are going to discuss about Circular Motion, which is class 11th chapter of Physics.
00:00:32We are going to discuss about Angular Displacement, Angular Velocity, Angular Acceleration.
00:00:42We are going to discuss the question of Circular Motion in today's lecture.
00:00:48So, are you all here?
00:00:52What's the matter?
00:00:54You came very early.
00:00:56Very good.
00:00:58No, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no
00:01:28no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no,

00:03:51body is moving on a circular path
00:03:56pay attention to the physics of the board
00:04:01here at t is equal to 0, the body starts from point A
00:04:06at t1 time theta 1 angle rotates
00:04:11at t2 time theta 2 rotates, so at t1 to t2 time this delta theta angle rotates
00:04:16this will be the angular displacement
00:04:21we will find the value here
00:04:26at t1 to t2, we will take the time interval
00:04:31the angle in this time interval will be delta theta theta 2 minus theta 1
00:04:36this is called angular displacement
00:04:41is there any problem?
00:04:46hello, is there any problem?
00:04:51the SI unit of angular displacement is radian
00:04:56SI unit, this is radian
00:05:01now what will be the dimension of this?
00:05:06how will we find the dimensionless quantity of angular displacement?
00:05:11tell me how will we find the dimensionless quantity?
00:05:16now see the angle
00:05:21angle is theta, arc upon radius
00:05:26one minute
00:05:31one minute
00:05:36one minute
00:05:41we will talk about all this later
00:05:46what is this?
00:05:51what is this?
00:05:56you people disturb me a lot, why do you think so much?
00:06:01without disturbance
00:06:06you people are sitting in the class and there is no disturbance
00:06:11is it possible?
