# CMAcceleration

The type of a structure containing 3-axis acceleration values.

```
struct CMAcceleration
```

## Overview

A G is a unit of gravitation force equal to that exerted by the earth’s gravitational field (9.81 m s−2).

## Topics

### Initializers

[`init()`](/documentation/CoreMotion/CMAcceleration/init())

[`init(x:y:z:)`](/documentation/CoreMotion/CMAcceleration/init(x:y:z:))

### Getting the Acceleration Values

[`x`](/documentation/CoreMotion/CMAcceleration/x)

X-axis acceleration in G’s (gravitational force).

[`y`](/documentation/CoreMotion/CMAcceleration/y)

Y-axis acceleration in G’s (gravitational force).

[`z`](/documentation/CoreMotion/CMAcceleration/z)

Z-axis acceleration in G’s (gravitational force).
