The acceleration property returns the amount of acceleration recorded by the device, in meters per second squared (m/s2).

Note: If the hardware doesn't know how to remove gravity from the acceleration data, this value may not be present in the DeviceMotionEvent. In this situation, you'll need to use DeviceMotionEvent.accelerationIncludingGravity instead.


var acceleration = instanceOfDeviceMotionEvent.acceleration;


The acceleration property is an object providing information about acceleration on three axis. Each axis is represented with its own property:

Represents the acceleration upon the x axis which is the west to east axis
Represents the acceleration upon the y axis which is the south to north axis
Represents the acceleration upon the z axis which is the down to up axis
