A rod PQ of mass M and length L is hinged at end P.A rod of weight W is supported by two parallel knife edges A and B and is in equilibrium…?.A rod of length is 3 m and its mass acting per unit length is directly proportional to distance…?.A ring of mass m and radius r rotates about an axis passing through its centre and perpendicular…?. A particle of mass m = 5 is moving with a uniform speed v = 3√2 in the XOY plane along…?.A mass m supported by a massless string wound around a uniform hollow cylinder of mass…?.For a shorter radius, velocity will be high and for a higher radius, velocity will be low.When no torque is applied, the perpendicular velocity of a body is determined by the radius of the circle.The angular momentum of an extended object is expressed as L = I x ω.The angular momentum of a point object is expressed as L = r x p.The revolution of Earth around the sun reflects orbital angular momentum, whereas the rotation about its axis indicates spin angular momentum.Angular Momentum is of two types- Spin angular momentum and orbital angular momentum.Mathematically, the magnitude of angular momentum ‘L’ can be expressed as L = rmv sin Φ.Angular Momentum is defined as the property of any rotating object given by the product of the moment of inertia and angular velocity of the rotating object.Kinematics of Rotational Motion around a Fixed Axis Relation between torque and moment of inertia This is useful in space applications where a spacecraft's attitude is an important criterion to regulate. It locks on to the orientation when turned at a rapid speed, and it will not deviate from it. It makes use of a three-degree-of-freedom spinning wheel. The principle of angular momentum is used by a gyroscope to maintain its position. Due to this, the angular momentum is conserved and they spin faster. When they require greater angular velocity to spin, they bring their hands and legs closer to their body. When the ice skaters initiate a spin, they position their hands and legs widely apart from their body's center. Some of the real life applications of angular momentum include: Ice-skater
