What is the difference between linear momentum and angular momentum?
Answers
Linear momentum is a property of objects which are changing their position with respect to a reference point.
Angular momentum is a property of objects which are changing the angle of their position vector with respect to a reference point.
Linear momentum of a system of particles is conserved so long as there is no resultant force on the system.
Angular momentum of a system of particles is conserved so long as there is no resultant torque on the system.
The rate of change of linear momentum of a system of particles is equal to the resultant force acting on the system.
The rate of change of angular momentum of a system of particles is equal to the resultant torque acting on the system.
Linear Momentum is measured in units of kg m2 s-1.
Angular momentum is measured in units of kg m2 s-1.
