Force of Head Striking a Marble Floow

AI Thread Summary
The discussion revolves around calculating the force of impact on the head after a fall from a height of approximately 9 to 10 feet onto a marble floor. The formula F=ma is mentioned, but the complexity arises from the variable 'a', which depends on how quickly the head decelerates upon impact. Factors such as the deformation of skin, muscles, and brain during the impact significantly influence the outcome. There is skepticism about the accuracy of such calculations due to the numerous variables involved, suggesting that using an accelerometer would provide a more reliable measurement. The individual seeks this information to better communicate the impact effects to healthcare providers.

Sorry, but my math is a bit rusty but -- Recently while using a wheel chair I fell from a lift banging my head on a marble floor. the lift was 6 feet off the ground, plus adding 4 feet while in a sitting position, the total fall was between 9 and 10 feet. Could someone help me calculate the force on my head when I hit the marble floor.

PS. broken back plus ribs. But I would really like to know the force on my head at point of impact. would i use the general formula F=ma. But i would really like someone knowledgeable in math/physics to do the calculation.\

thanks

Yes the formula is f=ma, the complexity is that the 'a' is the rate at which your head slowed down as it hit.
And so depends on the details of how your skin, muscles and brain deformed on microsecond timescales.
Then there is the question of how much force/energy/momentum is transferred to which organs in your head on what timescale to asses any possible damage.
 
This is no joke -- it happened and I've been suffering the effects of it for a year. I need a way to convey the impact on my brain to my doctors / health care therapists. So please help calculate because I can't.
 
Your doctor can't diagnose a concussion? These types of calculations are misleading at best. There are so many factors involved that influence the time of deceleration that the only viable way to do this is to measure the shock with an accelerometer.
