This high school teacher (formerly a worker at NASA) claims to have come up with a calculation for how it wastes less gas to have the air conditioning turned on versus rolling down the windows. I told my friend this teacher must be a complete moron, but my friend insists that I should "broaden my horizon." So, do you think this theory is pathetic or not?
Answer:
You're talking about a moving car of course. The idea is that rolling down the windows causes more drag from the air.
It's a close call and depends on the exact car, speed, temperature, etc.
The teacher is not a moron, although the issue is not easy to calculate exactly.
that doesnt make any sense she should give people an explanation not just say that .
What is the theory? You have just made a statement.
He could be right. Opening windows on a car causes more drag due to wind resistance. In order to overcome this resistance more gas would be used.
