## Detailed Description

The QAccelerometerReading class reports on linear acceleration along the X, Y and Z axes.

#### QAccelerometerReading Units

The scale of the values is meters per second squared. The axes are arranged as follows.

A monoblock device sitting at rest, face up on a desk will experience a force of approximately 9.8 on the Z axis (ie. towards the roof). This is the proper acceleration the device experiences relative to freefall.

## Property Documentation

### x : const qreal

This property holds the acceleration on the X axis.

The scale of the values is meters per second squared.

Access functions:

qreal | x() const

See also QAccelerometerReading Units.

### y : const qreal

This property holds the acceleration on the Y axis.

The scale of the values is meters per second squared.

Access functions:

qreal | y() const

See also QAccelerometerReading Units.

### z : const qreal

This property holds the acceleration on the Z axis.

The scale of the values is meters per second squared.

Access functions:

qreal | z() const
