```cs
[UiInfo("Collection of standard meta data keys associated with physical properties of objects.")]
public static class StandardNames.Physics
```

Collection of standard meta data keys associated with physical properties of objects.

## Fields

- [Density](https://developer.rhino3d.com/api/gh2/type/grasshopper2.data.meta.standardnames.physics/density.md): (static) Name for specifying the Density of a material.
- [Material](https://developer.rhino3d.com/api/gh2/type/grasshopper2.data.meta.standardnames.physics/material.md): (static) Name for specifying a material type.

## Methods

- [ParseDensity](https://developer.rhino3d.com/api/gh2/type/grasshopper2.data.meta.standardnames.physics/parsedensity.md): (static) Try and parse the density stored in metadata. This method will inspect both the [StandardNames.Physics.Density](https://developer.rhino3d.com/api/gh2/type/grasshopper2.data.meta.standardnames.physics/density.md) and [StandardNames.Physics.Material](https://developer.rhino3d.com/api/gh2/type/grasshopper2.data.meta.standardnames.physics/material.md) entries.
