What else can I help you with?
Is the direction of angular velocity same as that of angular momentum when agular velocity is decreasing?
Yes, suppose a body is rotating anti-clockwise, then its angular velocity and angular momentum, at any moment are along axis of rotation in upward direction. And when body is rotating clockwise, its angular velocity and angular momentum are along axis of rotation in downward direction. This is regardless of the fact whether angular velocity of the body is increasing or decreasing.
What is the relationship between the direction of angular momentum and the motion of a rotating object?
The direction of angular momentum is always perpendicular to the axis of rotation of a rotating object. This means that as the object rotates, its angular momentum will also change direction, influencing its motion and stability.
Is angular momentum a vector quantity?
Yes, angular momentum is a vector quantity because it has both magnitude and direction.
How can linear momentum be converted to angular momentum?
Linear momentum can be converted to angular momentum through the principle of conservation of angular momentum. When an object with linear momentum moves in a curved path or rotates, its linear momentum can be transferred to create angular momentum. This conversion occurs when there is a change in the object's direction or speed of rotation.
Is angular momentum a vector quantity?
Angular momentum is a vector quantity. Angular velocity, which is a vector quantity, is multiplied by inertia, which is a scalar quantity.

When is the angular momentum of a system not conserved?
The angular momentum of a system is not conserved when external torques are applied to the system. These torques can change the angular momentum by causing the system to rotate faster or slower or by changing the direction of its rotation.
How the direction of angular momentum is given by right hand rule?
Angular momentum = r x p... That is position vector r, CROSSED (not multiplied) with momentum vector p. So, to find out the direction the angular momentum will act, take ur right hand, point your fingers in the direction of r, and "curl" (close/bend whatever u wanna call it) ur FINGERS (not thumb) towards p. New, whichever way ur thumb points, that is the direction of the angular momentum Hope that helped
What is the relationship between angular momentum and the cross product in physics?
In physics, angular momentum is related to the cross product through the formula L r x p, where L is the angular momentum, r is the position vector, and p is the linear momentum. The cross product is used to calculate the direction of the angular momentum vector in rotational motion.
How can you find the direction of angular momentum if the position vector and force vector lie on the plane?
By finding the direction of angular velocity because it's always parallel to it.
Angular momentum is a measure of?
angular momentum is the measure of angular motion in a body.
What is the difference between linear momentum and angular momentum, and how does this difference impact the motion of objects?
Linear momentum is the momentum of an object moving in a straight line, while angular momentum is the momentum of an object rotating around an axis. The main difference is the direction of motion - linear momentum is in a straight line, while angular momentum is in a circular motion. This difference impacts the motion of objects by determining how they move and interact with their surroundings. Objects with linear momentum will continue moving in a straight line unless acted upon by an external force, while objects with angular momentum will continue rotating unless a torque is applied to change their direction.
