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.
Stress testing gives your doctor information about how your heart works during physical stress. Some heart problems are easier to diagnose when your heart is working hard and beating fast. During a stress test, you exercise (walk or run on a treadmill or pedal a bicycle) to make your heart work hard and beat fast.Tests are done on your heart while you exercise. You may have arthritis or another medical problem that prevents you from exercising during a stress test.he stress part of a stress test (when you're exercising or given medicine that makes your heart work hard) usually lasts about 15 minutes or less. However, there's prep time before the test and monitoring time afterward.
