The process in which organ systems work to maintain a stable internal environment is called homeostasis. Keeping a stable internal environment requires constant adjustments. Here are just three of the many ways that human organ systems help the body maintain homeostasis:
Respiratory system: A high concentration of carbon dioxide in the blood triggers faster breathing. The lungs exhale more frequently, which removes carbon dioxide from the body more quickly.
Excretory system: A low level of water in the blood triggers retention of water by the kidneys. The kidneys produce more concentrated urine, so less water is lost from the body.
Endocrine system: A high concentration of sugar in the blood triggers secretion of insulin by an endocrine gland called the pancreas. Insulin is a hormone that helps cells absorb sugar from the blood.
The concept of momentum tells us that it is equivalent to the product between the mass and the velocity of the object, that is to say that in general it can be written as
![p = mv](https://tex.z-dn.net/?f=p%20%3D%20mv)
Where,
m = mass
v = Velocity
Our values are given as,
![m = 0.145kg](https://tex.z-dn.net/?f=m%20%3D%200.145kg)
![v = 67mi/h = 30m/s](https://tex.z-dn.net/?f=v%20%3D%2067mi%2Fh%20%3D%2030m%2Fs)
Replacing we have that,
![p = (0.145)(30)](https://tex.z-dn.net/?f=p%20%3D%20%280.145%29%2830%29)
![p = 12.45 kg\cdot m/s](https://tex.z-dn.net/?f=p%20%3D%2012.45%20kg%5Ccdot%20m%2Fs)
Therefore the magniude of the momentum of the pitched baseball is ![12.45 kg\cdot m/s](https://tex.z-dn.net/?f=12.45%20kg%5Ccdot%20m%2Fs)
On or near the surface of the Earth, 1 newton is the weight of about 102 grams of mass.
Note that the gravitational force between the object and the Earth is always the
same. It doesn't matter whether the object is falling, flying, floating, fluttering,
rising, sinking, rolling, sliding, or just laying there. It doesn't change.
