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.
There are many things that can cause chest pain. Reflux can make a person think she is having a heart attack. Heart issues, of course, and there are many types of heart issues. Lung issues can cause chest pain, as well as musculoskeletal or neurological problems. An EKG doesn't tell you your heart is fine. It is a snapshot that says you are not having a rhythm problem at that moment the test is done. It is a screening test more than anything else. As far as the stress test, if you can't do the walking one you lie down and have a stress test where your heart rate is increased with medication rather than exercise. So you can get the stress test done whether you can do a treadmill or not. Blood vessel issues or anxiety can also cause chest pain. There are just a lot of possibilities here.
