## acceleration

change in motion of a body or object: the rate of change of velocity with respect to time.**the rate of change in linear velocity with respect to time; related to force by Newton's second law of motion (often stated as force = mass×linear acceleration). Measured in metres per second squared (m.s**

*linear acceleration:*^{-2}).

**the rate of change in angular velocity with respect to time. Measured in degrees per second squared (°.**

*angular acceleration:**s*

^{-2}) or radians per second squared (rad.s

^{-2}); related to moment by Newton's second angular law of motion (moment = moment of inertia×angular acceleration).

**the acceleration of an object or body acting at a tangent to its direction of motion, e.g. when it is moving in a circle or around a curve.**

*tangential acceleration:***acceleration measured over a very short (infinitesimal) period of time, effectively a continuous measurement of acceleration.**

*instantaneous acceleration:**See also*

**gravitational acceleration.**

## 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 :
