acceleration

 [ak-sel″er-a´shun]
1. a quickening, as of the pulse rate.
2. in physics, the time rate of change of velocity.
psychomotor acceleration generalized physical and emotional overactivity in response to internal and external stimuli, such as that seen in the manic phase of bipolar disorder.

ac·cel·er·a·tion

(ak-sel-er-ā'shŭn), Avoid the mispronunciation uh-sel-er-ā'shŭn.
1. The act of accelerating.
2. The rate of increase in velocity per unit of time; commonly expressed in g units; also expressed in centimeters or feet per second squared.
3. The rate of increasing deviation from a rectilinear course.

Patient discussion about acceleration

Q. What herbs are known to be helpful against Arthritis acceleration?

A. mind you- herbs most of the time contain the same medication that pills do but without an exact amount and accompanied with other materials. there is great danger in that area, here is a guide for choosing a herbal supplement that will give you some tips :
