Angular velocity and its direction | v = ω x r | Angular acceleration | fixed point & Axis Rotation
In this video, we will start by introducing the concept of angular velocity and its relation with the linear velocity. We found that v = ω r, angular frequency ω can't be a scalar quantity because r and V are not parallel. Angular frequency is a vector quantity and its direction is given by the right hand rule or right hand screw rule. angular frequency is always along the rotational axis and using right hand rule for vector cross product we come up with v = ω x r. This relation is a general relation valid for fixed point and fixed axis rotation. In fixed axis rotation the direction of angular frequency do not change but in fixed point rotation it do change. Magnitude of angular frequency can change in both type of rotation. Thereafter we introduce the concept of angular acceleration and its relation with the linear acceleration, Here we have tangential acceleration and centripetal acceleration. angular velocity,v = ω x r, angular acceleration, why angular velocity is a vector, direction of angular velocity, angular velocity is vector or scalar, relation between angular velocity and linear velocity, fixed axis rotation, fixed point rotation, rotational motion, tangetial acceleration, centripetal acceleration, centrifugal acceleration, angular velocity class 11, angular velocity physics, angular velocity class 11 physics, angular velocity and angular frequency, physics #physicsconcept #physics #physicsclass11 #class11 #class11physics #neet #neetexam #jeemains #jee #jeeadvanced #jeemain #jeemains #ncert #ncertsolutions #ncertphysics #ncertsolution #cbseclass11 #systemofparticlesandrotationalmotion #systemofparticles #rotationaldynamics #rotationalmotion #rotational_motion #rotational_dynamics #rotational #chapter7 #centreofmass #centreofgravity #rigidbodydynamics #rigidbody #motion #frameofreference #vector #vectors #crossproduct #vectorproduct #righthandthumbrule #angular #angularvelocity #angularmomentum #angularacceleration #torque #couple #momentofforce #momentofinertia #centrifugalforce #centripetalforce #centripetalacceleration
