Description
Motivation
What I want to do is apply a velocity to a rigid body in a specific direction. This can be useful in cases where I want to simulate an impact, especially when the user is not concerned with how the impact affects the static object, but rather the deformable one.
Proposal
Velocity override option for static or rigidbody.

Research direction
Start by tracing how static and rigidbody contact states are represented and how velocity is currently applied during simulation. Clarify whether the override affects only the rigid body, how direction and timing are specified, and how existing physics behavior should remain unchanged. Done should include an agreed API, implementation, and tests covering the override for both object types.
