Getting Entities PhysObject/Velocity On The Client?

I have an entity with a valid physobject, and I am trying to get the velocity of this entity from the client. However, trying to get the physobject returns nil on the client.

I assume the client must be sent the velocity of entities from the server for interpolation, so how can I get this value?

I know I could just network the value from the server but this seems inefficient, considering I need the velocity every frame.

Entity:GetVelocity

Oh wow, that was simple.
