Did anything happen to F = m × a in the last 20 years?
Acceleration a is heavily dependent on the mass m.
Since a = F / m having half the mass would result in double the acceleration with same amount of force F available.
- thedufer 11y agoUnlike in high school physics, we have to account for drag, which is a lot more important than mass at these speeds. F=ma is true, of course, but you have to think more about what F really is.
- mapt 11y agoThe same amount of force F is not available. If they're putting athletes into this thing, the bigger the athlete, the more force (okay, the more power) is available for propulsion. They have bigger muscles which store more glycogen and have greater total mitochondrial activity, because there are simply more of these cells available to do the work.
