Tippy Teo to Newton's First law

Your probably thinking," How am I suppose to know what Newton's First Law is "? Well to summarize, Newton's first law involves with an object in motion and staying in motion . Also the object stays at the same speed and in the same direction. Take this move for an example the ballerina elevates on her toe's and has to move at the same speed to keep her blances. She is also in motion and stay's in motion until it's time for her next move.
