Mass doesn't affect speed directly. It determines how quickly an object can change speed (accelerate) under the action of a given force. Lighter objects need less time to change speed by a given amount under a given force.Alternatively, mass determines how strong a force has to be to accelerate an object at a given rate. Lighter objects can do with weaker force to change speed by a given amount in a given amount of time.Thus, mass is a measure of object's inertia which is resistance to changes in object's motion.This is what the equation. \begin{equation} F=ma \end{equation}. means.ighter objects can do with weaker force to change speed by a given amount in a given amount of time.

Ive seen world specialists regards it but im willing to give a TENS machine a go if it will help with pain management. Ive read that the electrical pulses from TENS machines maximum depth is around 2 inches, so Im assuming this will not be deep enough to effect the heart muscle itself and cause rythym problems.
