# Two masses connected by constant distance

## Main Question or Discussion Point

Hello, apologize if this is basic for some of you. Its been a while since I've taken physics and I'm looking to model an interaction similar to the dual ships in the classic video game Space Duel.

Basicly two masses connected by a rigid connector (constant distance). One mass (m1) does all the accellerating. The other (m2) gets dragged ( also effecting the ability of m1 to accellerate), causing both to rotate about each other at the midpoint of the connector (sort of like a bolas effect) while the entire mechanism (both masses and connector) move about the field. This is a 2D flat space.

I'm thinking a spring connector model (please correct me if I'm wrong) with 0 expansion or retraction, but am not sure how to go about modeling this. Any help would be appreciated.

What exactly are you trying to find? Force is a vector quantity, could you please attach a diagram?

Hi KN, thanks for your time. I'm trying to find the equations to program the model I'm describing. Here's an example of the original game to see the ship behaviors I'm talking about that I'm trying to model (look at the 1 Player cooperative play):
