Join Aaron F. Ross for an in-depth discussion in this video Imparting initial velocity, part of Maya Dynamics: Creating Simulations (2012).
We're ready now to actually create some animation with our little bowling alley.…We need to get that ball rolling down the lane.…Now we can do that in multiple ways, we could create keyframes on the ball and…then key it's active attribute.…However, the simplest thing to do here is to simply apply an initial velocity…that will be the speed of the object at the first frame of the animation. I'll…select the ball and scroll down on the Channel box and open up that Rigid Body…node and you will see Initial Velocity X, Y and Z right up at the top.…
These values will cause the object to move in whatever cardinal direction in X,…Y or Z space and a positive value will cause the object to move in positive X or…positive Y and negative value would cause it to move in the negative direction.…In my scene currently I want the ball to move this way and that's actually…negative Z in my scene.…I need to give a negative value to Initial Velocity Z: let's try value of…-100. Rewind and play that back and you'll see it is rolling along, but it…
