To walk on ice while conserving momentum, focus on minimizing the friction between your feet and the ice by taking slow and deliberate steps. By keeping your center of mass over your base of support, you can maintain stability while walking on the slippery surface. Additionally, using shorter steps and maintaining a low center of gravity can help you adapt to the reduced friction on ice.
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.
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.
An example of conservation of momentum is when two ice skaters push off each other on a frictionless surface. As they push off in opposite directions, the total momentum of the system remains constant before and after the interaction, even though their individual momenta change.
Collisions between billiard balls where the total momentum before the collision is equal to the total momentum after. Recoil of a gun when a bullet is fired, where the forward momentum of the bullet is equal and opposite to the backward momentum of the gun. Ice skaters pushing off each other in opposite directions, resulting in a conservation of momentum system.
The person can throw something in the opposite direction, like their clothing, to propel themselves towards the shore due to conservation of momentum. When the person throws the clothing, they will move in the opposite direction with an equal force, allowing them to gradually reach the shore. This is based on the principle that momentum is conserved in a closed system.

Their masses are equal. According to the law of conservation of momentum, the total momentum of the system will remain constant before and after the push-off. Since the two ice skaters have equal and opposite momenta after the push-off, their masses must be equal in order to fulfill this conservation law.
The momentum of the ice skater can be calculated using the formula: momentum = mass x velocity. Plugging in the values (mass = 50 kg, velocity = 2 m/s), the momentum would be 100 kg*m/s.
It is 250 kgm/s in the direction of the skater's motion.
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.

The angular momentum of the ice skater spinning with her arms out and not being acted upon by an external torque remains constant.
