It should be noted that the angular momentum remain constant  and kinetic energy of the skater increases.

<h3>What is Angular momentum?</h3>

Angular momentum  can be regarded as the property of any rotating object given by moment of inertia times angular velocity, since No net torque is done on the object, then  angular momentum is constant.

Kinetic Energy which is also the energy of motion in the Ice skater will increase since their is a pull.

According to Newton's 3rd Law of Motion, when you walk on the sidewalk, the push of your shoe on the ground is _______ the push
Nady [450]

Answer:

opposite

Explanation:

Newton's 3rd law of motion: If object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.

so it should be opposite because the ground/floor pushes the shoe up and forward, the shoe pushes down and back.

correct me if you see a mistake.
