Angular caprice and its properties were devised over time by many of the bulky minds in physics. Newton and Kepler were probably the two biggest factors in the growth of angular momentum. Angular momentum is the personnel department which a abject body, following a curved path, has because of its ken and motion. Angular momentum is possessed by rotating objects. Understanding torque is the first stair to understanding angular momentum.
Torque is the angular version of cart. The units for torque be in Newton-meters. Torque is observed when a force is exerted on a rigid object pivoted about an axis and. This results in the object rotating around that axis. The torque ? due to a force F about an origin is an inactionl frame delimit to be ? ? r x F1 where r is the vector position of the affected object and F is the force applied to the object.
To understand angular momentum easier it is wise to study it to the less complex linear momentum because they are resembling in many ways. Linear momentum is the product of an objects mass and its instantaneous velocity. The angular momentum of a rotating object is granted by the product of its angular velocity and its moment of inertia.
unspoiled as a moving objects inertial mass is a measure of its resistance to linear acceleration, a rotating objects moment of inertia is a measure of its resistance to angular acceleration.2 Factors which stamp a rotating objects moment of inertia are its mass and on the distribution of the objects mass about the axis of rotation. A low object with a mass concentrated very remainder to its axis of rotation will have a smallish moment of inertia and it will be fairly unclouded to spin it with a certain angular velocity.
