I found this a little confusing as velocity and distance seem to have the same units. Or did you mean to write v-1?
- alexhwoods 11y agoGood question! Each iteration of the model occurs for one unit of time. Because of this, we can directly compare distance and velocity. Like if velocity was meters per second, and distance was meters, since the velocity update occurs for one second, we can compare the two. I'll clarify in the post, this confused me too when I first started reading about the model.
- lindig 11y agoIf you adjust the velocity to v-1 it would be an incremental update, which seems natural. But if you update the velocity to d-1 (as stated) I can imagine this could be a jump and even could result in negative velocity for d=0.
