Linear acceleration from MPU 6050 When reading the MPU 6050 has accelerometer and gyro, I assumed it was linear acceleration, but now I second guess that.  From this video https://www.youtube.com/watch?v=qmd6CVrlHOM it seems like they are using acceleration and gyro to make one rotation direction.  I need to know what direction the mpu is moving, not just a rotational value.  Is there a way to extract this information?
The MPU6050 has an accelerometer and a rate gyro (which tells you how fast it is rotating). The accelerometer will tell you which direction is down and in a motionless situation, that is all the information you have.

You'll probably want something like the MPU9150, it has a compass, which will give you the directional information you're asking for.
