Question
If you could skate on a perfectly smooth, frictionless surface (like ice!), what would happen when you push yourself once?
Solution
If you were to push yourself once on a perfectly smooth, frictionless surface, you would continue to move in the direction of the push indefinitely. This is due to Newton's first law of motion, which states that an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. In this case, the lack of friction means there is no unbalanced force to slow you down or change your direction after the initial push.
