I guess 9 DOF might use a magnetometer, such that you add North, South, East, West degrees of freedom, or perhaps, pressure for elevation. Or perhaps it is used to describe a articulated robotic arm.
An accelerometer is typically a bit slow to react to changes when rolled on an axis, a Gyroscope allows fast reactions to axial rotation, but have a tendency to drift. An accelerometer with gyroscope allows for fast reactions to axial rotation, and the accelerometer prevents the longer term drift. This MPU-6050 simplifies the process of getting this kind of data and it does it for low $.
