.SYNOPSIS
Calculates centripetal acceleration.
.DESCRIPTION
Uses a = v² / r.
.EXAMPLE
```powershell
Get-CentripetalAccelerationByVelocityAndRadius -VelocityInMetersPerSecond 10 -RadiusInMeters 5 -As ""g""
```

Calculates centripetal acceleration for velocity 10 m/s and radius 5 m, output in g units.
.EXAMPLE
```powershell
Get-CentripetalAccelerationByVelocityAndRadius 20 10
```

Calculates centripetal acceleration for velocity 20 m/s and radius 10 m using positional parameters.
