In case of Russian dance, the dancer will spin her body about the vertical axis passing through her toe. If she keeps extending her hands then number of rotation and so angular velocity will be less. If she brings her hands close to her body then number of rotations would increase. Same scene could be enjoyed in case of circus with girls hanging just with a tight hold with their teeth.
Elastic collision.
One of the best examples that demonstrates the conservation of angular momentum is the spinning ice skater. When a skater pulls in their arms while spinning, their rotational speed increases due to the conservation of angular momentum. This principle shows that the total angular momentum of a system remains constant unless acted upon by an external torque.
One example of conserved momentum is a collision between two objects where the total momentum before the collision is equal to the total momentum after the collision. This is known as conservation of momentum.
One of the best examples of transfer of momentum is when a cue ball strikes a stationary billiard ball, causing the stationary ball to move while the cue ball slows down or stops. This transfer of momentum demonstrates the principle of conservation of momentum in action.
There are several laws of conservation; please clarify which one you mean. For example, there is the law of conservation of mass, of energy, of momentum, of rotational momentum, of electrical charge, and others.
An example of an event when momentum is not conserved is when two ice skaters on frictionless ice push off each other. When they push off, one gains momentum in the opposite direction, causing the total momentum of the system to change from the initial state. This violates the principle of conservation of momentum.
Always. There are no expections to the conservation of momentum.
The equation that best describes the law of conservation of momentum is: m1v1_initial + m2v2_initial = m1v1_final + m2v2_final This equation states that the total momentum of a closed system before a collision is equal to the total momentum after the collision.
In an isolated system the total momentum of a system remains conserved. For example If you fire a bullet from Gun , bullet go forward with some linear momentum and in order to conserve the linear momentum the gun recoils
An example of the principle of conservation of momentum, which states that the total momentum of an isolated system remains constant before and after a collision.
