SUMMARY

The discussion centers on the physiological effects experienced by pilots when pulling out of a steep dive, specifically the tendency to black out. Participants reference Newton's laws of motion, particularly the implications of circular motion and gravitational forces on blood circulation. The consensus is that the rapid change in direction and speed, known as "pulling G's," causes blood to be pushed away from the brain, leading to potential loss of consciousness. Understanding these forces is crucial for comprehending pilot safety and performance in aviation.

Homework Statement


why does a pilot tend to black out when pulling out of a steep dive?

Homework Equations


Newton's 2nd and 3rd laws

The Attempt at a Solution


I think the pilot passes out because the downward force of the plane pushes all the blood away from his brain and causes him to pass out.

I read the rules of this forum so I don't expect an answer. But please push me in the right direction because I know I am forgetting something.

Almost. But I don't think the plane is pushing down. What forces are associated with circular motion, because it's the pulling out of a dive, you know a radius and a high speed, as the pilots say "pulling G's". How is that force directed may be more to your interest?

Hi aaronb! :smile:

I think it's more Newton's first law …

if you bounce off a trampoline, what does your blood "want" to do? :wink:
