How are units interpreted from simulink to physical signals in SimScape?

I don't have any compiler error or fatal errors. I am attempting to model a person "pumping" on a swing to go higher. I'm starting with a small (approximating a point) mass traveling upward on a rigid body. I'm using a prismatic joint on a simple pendulum and I have input motion actuation as a step function with varying values, none of which seem to cause any actuation. I don't know what units the physical signal is sent in at, I just attached a step signal to a Sim->PS converter and put that as input for motion actuation.

Any reference is appreciated as much as instruction or guidance.

If you leave the unit at "1" in the PS-Simulink/Simulink-PS Converter blocks, Simscape models will use the default units for that particular variable.

In the case of motion, the default unit is meters (or m).

This page has the full list you can use.
