angular momentum and angular velocity
angular mmtm is a cross product unlike linear momentum
Angular velocity is a vector with a direction and angular speed is a scalar with no direction.
If a body is moving in a straight line then it would have angular momentum about any point which is not along its line of motion. The magnitude of the angular momentum would be its velocity times the perpendicular distance between the line of motion and the point.
I believe that any particle in linear motion must also have some angular momentum because all particles have spin. In the case of a photon the spin, wavelength and angular momentum all vary with the relative linear velocity. So in my point of view time itself is the ratio between relative linear and angular momentum.
Torque is the rate of change of angular momentum.
momentum is product of moment of inertia and angular velocity. There is always a 90 degree phase difference between velocity and acceleration vector in circular motion therefore angular momentum and acceleration can never be parallel

linear velocity= radius* angular velocity
moment is nothing but a force but momentum is the product of mass and velocity.
Momentum is the product of mass and velocity. Energy is the capacity of a body to do work.
The larger the momentum, the harder it will be to stop it. Thus, the larger the force needed to decelarate the object. Since momentum is directly proportional to the velocity, the larger the momentum, the larger the velocity.
To preserve the conservation of; energy, momentum, and angular momentum in beta plus decay. Without the neutrino there is a measurable difference between the energy, momentum, and angular momentum of the initial and final particle. The neutrino rectifies this difference and it's existence was actually postulated before it was ever discovered!
