Explain why the points x = A and x = -A in Fig. 7.23b are called turning points. How are the values of E and U related at a turning point?

Fig. 7.23b

On the graph, the limits of motion are the points where the U curve intersects the horizontal line representing total mechanical energy E.

и -Jue -E = K + U х -A

-Jue -E = K + U -A
