The basic formula for the penguin flying through the air is x += dt + v
If this is calculated 30 times per second you basically get x += dt +
30v, but if you calculate it 32 times per second, you get x +=
(dt*0.937) + 32v
That formula (x += dt + v) doesn't seem right to me.
if velocity is v meters per second, then the distance travelled in time interval dt is v*dt, isn't it?
so I'd expect x += v*dt always.
I don't see what this dt + v is about, much less the (dt*0.937) + v. I get that 30/32 is 0.9375, but I expect to see that multiplied by velocity not added.
Can you explain to me what's going on?
