I've simply found that it's hard to judge intuitively how much speed will be required to coast to the top of a hill. I've come to realize that this is because the
vertical distance is not a function of velocity, but of velocity squared.

What do you want the needle sweep from 0-60 mph to be? - 60*
- 40* (my understanding)
- Some other number of degrees. (If so, what number?)
If the answer is 40*, I'd don't see why you'd need/want any additional scale markings other than km/h. |
Yes, 40 degrees.
The speed markings (both mph and kph) would be on a parabolic scale. They would start out squnched together and spread apart as the speed went up. The rise (in feet/meters) would be a linear scale, just like the current speedometer.
What I think I'm going for is trying to get a better intuitive grasp on how much kinetic energy I have and how much drag I'm experiencing. Maybe it won't do a whit of good, or maybe I'll be surprised.
