The kinetic energy is increasing between points 10 and 11, and also between points 12 and 13 on the graph.
The potential energy in the graph is represented by the blue line. The potential energy is increasing when the blue line is sloping upwards, and it is decreasing when the blue line is sloping downwards. The potential energy remains the same when the blue line is horizontal.
The kinetic energy is increasing at the following points in the graph:
Between points 10 and 11
Between points 12 and 13
At these points, the blue line is horizontal, which means the potential energy is not changing. However, the system is still moving, so its kinetic energy must be increasing.
