Suppose you are playing ice hockey in the middle of a totally frictionless frozen pond.How can you move youself to the edge of the pond ?

If it is totally frictionless, you only need to throw the hockey stick to one side and wait for yourself to move slowly to the other side. This will happen by the law of conservation of momentum, and Newton's first law (continues to move in a uniform velocity without external, i.e. friction, forces).

I wonder how you are standing on a totally frictionless surface, much less how you would throw something, or swing a hockey stick.

Haha, it's all hypothetical.

We're supposed to be playing hockey on a totally frictionless ice rink!
I think crutches with sharp ends would help.

To move yourself towards the edge of the frictionless frozen pond while playing ice hockey, you can utilize Newton's third law of motion, which states that every action has an equal and opposite reaction. This principle allows you to propel yourself by pushing off against another object or exerting force in a specific direction. Here are a few ways you can move yourself towards the edge of the pond:

1. Swing your arms and use your stick: By swinging your arms and stick in one direction and then quickly pushing off in the opposite direction, you can create a reactionary force that propels you in the desired direction. This action mimics the motion of a swimming stroke in the air, allowing you to move forward on the frictionless surface.

2. Bending and extending your legs: You can flex and extend your legs alternatively, similar to a jumping jack motion, to generate a forward or backward push. By pushing your legs in one direction and then extending them in the opposite direction, you create a reaction that propels you forward.

3. Utilizing another object: If there is another object available on the ice, such as a wall or hockey goal, you can push off against it to gain momentum towards the edge. By exerting force against the object and then rebounding off it, you create a reactionary force that moves you in the opposite direction.

Remember, since the pond is totally frictionless, any initial movement or push you give yourself will continue in a straight line until interrupted or countered by another force. Therefore, it is crucial to plan your movements carefully and use the principles of action and reaction to gradually propel yourself towards the edge of the pond.
