Is angular momentum conserved when a spinning ice skater pulls in their arms?
Yes, angular momentum is conserved when a spinning ice skater pulls in their arms. This is because the skater's rotational speed increases as they bring their arms closer to their body, balancing out the decrease in their moment of inertia.
When a skater glides across the ice on one skate what kind of motion does the skater have?
The skater would exhibit rotational motion as well as translational motion during the glide. Rotational motion is the spinning of the skater around their own axis, while translational motion is their movement across the ice in one direction.
What is the momentum of a 50 kg ice skater gliding across the ice at a speed of 5 ms?
It is 250 kgm/s in the direction of the skater's motion.
Why are speed skates shaped so oddly?
so the skater can have a better turning on the ice
What is the momentum of a 50 kilogram ice skater gliding across the ice at a speed of 5 m's?
500 kg·m/s
What is the momentum of a 50-kilogram ice skater gliding across the ice at a speed of 50?
250 kg * m/s
Is ice skater a compound word?
Ice skater is not a compound word.
An ice skater glides around a rink at a constant speed of 2 ms is the skater acceleratng explain your answer?
Acceleration is change in velocity. These are vectors that have magnitude and direction. Changing either magnitude (speed) or direction will have the skater be accelerating. SO, if the skater is going at a constant speed of 2m/s in a straight line, he is not accelerating. If he is at a constant speed of 2m/s traveling in a circle (you gave the word "around"), he is accelerating. Going around in circles means there is a force constantly changing your direction. Obviously that force is coming from the skaters legs.
How does change in pressure help in ice skating?
When ice skating, applying pressure on the ice with the blade of the skate helps create friction between the blade and the ice, allowing the skater to push off and glide smoothly. By adjusting the pressure applied to the skate, a skater can control their speed, direction, and stability on the ice. Changes in pressure also help to initiate turns and maneuvers while skating.
What is the best example that demonstrates the conservation of angular 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.

What is the part of the blade that controls change in direction while speed skating?
This is a multi-answerable question. Without the "rocker" of the blade, you wouldn't be able to change the direction of your foot while it's on the ice. But modern day speed skates are all rockered so that the skater can change direction when needed. But the skater can always pick up his/her foot and place it in a different direction, making the person go in tat direction.
