WebThe angular momentum of the body after torque induced is, L 2 = r x P 2 L 2 = 1.5 x 100 L 2 = 150kgm 2 /sec The torque acting on the rotating body is calculated as, T=dL/dt π=L 2 -L 1 /t 2 -t 1 Substituting all values, π=150-75/2-0 π=75/2 π=37.5 The torque acting on the body is 37.5Nm. Find Torque from Angular Momentum Web4 hours ago · However, the total momentum of the system (the sum of the momenta of the two objects) will remain constant. Conservation of Angular Momentum: The law of conservation of angular momentum states that the total angular momentum of a closed system remains constant. Angular momentum is a measure of an object’s rotational …

WebAngular momentum is a conserved quantity as there is constant angular momentum in a closed system. The formula for angular momentum is, L = r x p Where, L is the angular velocity r is the radius (the distance between the object and the fixed point it revolves around) p is the linear momentum. Table of Content What is Angular Momentum? WebThe total angular momentum is the sum of the spin and orbital angular momenta.
