Velocity spinning bike4/8/2024 ![]() If the sum of the torques on an object is equal to zero, then the total angular momentum will be conserved and will have the same final value as it did initially.Ī fun example of the conservation of angular momentum can be demonstrated with a bike wheel and a rotating chair. If a torque acts on an object, the angular velocity of that object will change, along with its angular momentum. Where is the distance to the axis of rotation and is the force applied. When the fingers of the right hand curl in the direction of rotation, the extended thumb points in the direction of angular momentum.Ī torque is defined as the product of a force applied at some distance from an axis of rotation: The right-hand rule can be used to determine the direction of angular momentum. The larger the moment of inertia, the more torque is needed to cause an angular acceleration on an object. It is related to the mass distribution of a rotating object and the axis of rotation. The moment of inertia is the rotational analog of mass for linear motion. Where is the moment of inertia and is the angular velocity.
