Yerçekimi ivmesi; bir vakum ortamı içerisinde serbest düşmeye bırakılan bir cismin hızında birim zamandaki artış miktarı; değeri enlem ve yükseltiye göre değişir; deniz düzeyinde ve 45° enlemdeki uluslar arası standart yer çekimi ivmesi 9.806 65 m/s2 ya da İP birim sisteminde 32.174 ft/s2 dir
The acceleration imparted to a body by the gravitational field of some small body, planet, star, galaxy, or cluster of galaxies; a measure of the intensity of a gravitational field
Any acceleration due entirely to gravity, e g , in a vacuum a freely falling body falls toward the earth's center at a velocity of 32 2 feet the first second, and an increased velocity of 32 2 feet per second the second second (velocity at the end of the second second is 64 4 feet per second, etc ) This is commonly expressed as 32 2 feet per second per second, or 32 2 feet per second square In air the rate of acceleration is modified by the force due to tair resistance A freely falling body will finally reach a speed at which the force of gravity and air resistance are equal and no greater speed is gained, i e , terminal velocity
The acceleration of freely falling bodies under the influence of terrestrial gravity, equal to approximately 9.81 meters (32 feet) per second per second
the gravitational acceleration of a freely falling object, expressed in terms of the rate of increase of velocity per second: on earth 980 665 cm (32 l7 ft ) per second per second is the standard
