Ivan Drago back in '85 got higher.

 

I don't believe this is correct. In fact it's not correct as force = mass x acceleration.

 

Mother ****er was also juicing. Had Rocky insisted on olympic stlye testing, he wouldn't have gotten ****ed up liked that and suffered brain damage.

 

Looking back that is a fair analysis. Pacquiao should take a note of that.

 

It's perfectly correct. Acceleration under gravity (ignoring affects of wind resistance which is irrelevant for this example) is uniform for every object on Earth, at approximately 9.8 m/s^2. Likewise your mass is obviously constant.

Therefore whether you fall from 100 feet, 10 feet, or 1 foot, the force you hit the earth with is always your mass times 9.8 m/s^2.

 

On the hit like a girl experment it is all a matter of technique. Mo throws a more textbook punch. While Rijker winds up more. The result is that Rijker delevers a punch with more power. She dose leave herself somewhat exposed but if your fast enough it won't matter. It is a risk though.

 

Technically you're correct. However, velocity is also a determinant of force, as there is more than one equation that defines force. Clearly if you're acceleration stays constant, your velocity increase the higher up you are. It takes a certain amount of force to break a human bone. Under your theory, it wouldn't matter how high you fell your force would remain constant and your chances of breaking a bone would be the same. We all know that's not true. Drop a penny from ten feet up on someone's head and it does no damage. Drop a penny from the empire state building and it will go through someone's head.

 

This urban legend has been debunked many, many times.

 

That still doesn't change the main argument, which is that velocity will increase force.

 

Nowhere was the validity of that statement put into question. Hence why it wasn't quoted.

 

Did you even finish high school? This is just high school physics.
F=ma is for static body - bodies that are stationary position. The energy force here is gravity: G = mgh where h is the height of fall.
Once moving you also have kinetic energy: K = mv*v/2 where v is the velocity, which will depend among other things on how long you are falling.
At the time of impact impulse and momentum will take over.

 

:thumbsup

 

LOL. The force remains constant but the energy increases. It's energy you have to dissipate when you hit ground. That's what counts.

 

This is a fragment.

 

The reason being is that a falling body will reach terminal velocity because of air resistance, hence the velocity will not increase anymore, hence the energy won't increase anymore.
