The salesman is telling you the average magnitude of the car's acceleration.
| Acceleration | = (change in speed) / (time for the change)
| Acceleration | = (60 mi/hr) / (6 sec)
| Acceleration | = 10 miles/hr-sec
That would be 36,000 miles per hour squared,
or 0.0028 mile per second squared.
The ones that interact would be Atmosphere, biosphere, and cryosphere. :)
Medicine to a patient. That should be calculated based on weight, strength/dosage and possibly other factors
