WebOn Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth’s mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects. At Earth ’s surface the acceleration of gravity is about 9.8 metres (32 feet) per second per second.

WebJan 27, 2016 · Gravity is a force, and according to Newton's Second Law, a force acting on an object will cause it to accelerate: F = ma Acceleration is a rate of change of speed (or velocity, if working with vectors). Speed is measured in m s, so a rate of change of speed is measured in m s s or m s2. WebJul 21, 2014 · ECG. A Brief introduction to ECG • The electrocardiogram (ECG) is a time-varying signal reflecting the ionic current flow which causes the cardiac fibers to contract and subsequently relax. The surface ECG is obtained by recording the potential difference between two electrodes placed on the surface of the skin. toys r us facebook page
