... kilograms (kg), and weight is calculated from W = mg. If the gravitational acceleration (g) is specified in units of m/s2, then the weight is expressed in newtons (N). On the earth’s surface, g can be taken as g = 9.81 m/s2. W (N) = m (kg) g (m/s2) => N = kg·m/s2 FPS System: In the FPS system of uni ...

... force there is an associated work and an associated energy. The stretching of a spring requires a force and performs work (active energy); that work is stored as energy in the spring for later use (passive energy). Forces (F) are vector properties; they have magnitude and direction (e.g., weight and ...

... We found in Module 5.5 that falling objects accelerate at a rate of 10 m/s2 (a more accurate number is 9.8 m/s2). We say that this is the acceleration of gravity (ag) for all objects. Knowing the mass (m) of an object and its acceleration due to gravity (ag) , the weight of any object (Fw) can be ca ...
