Answer» Thegravity of Earth, denoted byg, is thenet accelerationthat is imparted to objects due to the combined effect ofgravitation(from distribution of mass withinEarth) and thecentrifugal force(from theEarth's rotation). InSI unitsthis acceleration is measured inmetres per second squared(in symbols,m/s2or m·s−2) or equivalently innewtonsperkilogram(N/kg or N·kg−1). Near Earth's surface,gravitational accelerationis approximately 9.8m/s2, which means that, ignoring the effects ofair resistance, thespeedof an objectfalling freelywill increase by about 9.8 metres per second every second. This quantity is sometimes referred to informally aslittleg(in contrast, thegravitational constantGis referred to asbigG).
