Dot or Scalar Product of Vectors Dot Product of two vectors A and B is defines as product of magnitude of the vectors and cosine of the angle between them. A•B = |A||B|CosT, Where T is the angle...
It states that if net torque acting on an isolated system is zero, the angular momentum remains conserved. Since Torque is equal to the rate of change of angular momentum so when torque is zero, dL/dt=0 So,...
