Catherine was upset that she couldn't master her turns, but her flexibility was on point because she had her split down packed.
Cora was angry because, she could not get her center leap high enough like the others in her class.
Catherine and Cora had an important talk with their dance teacher Mrs. Nicky about the upcoming recital she wanted Catherine to do the turns and Cora to do leaps no acceptions.
Mrs. Nicky was helping Catherine with her turns. She was explaining to her that her force needed to decrease to perform the turn, because she applied to much force for her body mass, causing so much acceleration she fell out of her turns each time.
Mrs. Nicky was on a roll. She also helped, Cora with her center leap. She explained that when she was leaning down toward the floor her body mass was bringing her down affecting her height. Her force was the same and her acceleration and height of her leap improved.
The show was a success. Both of the girls mastered their goals, Catherine with her turns and Cora with her center leap. With Newton's Second Law. Which explains Force= Mass*Acceleration. Grasping this key concept helped the girls meet their expectations before the recital. Thanks to Newton's second law and the help of their dance teacher, Mrs. Nicky. The End
