重力是指地球表面附近物体所受到的地球引力,它还受到因地球自转而产生的惯性离心力的微小影响,同一物体在地球上不同纬度和高度所受重力稍有不同,愈近两极和愈近地面,重力愈大,广义上任何天体使物体向该天体表面降落的力都称重力。例如:月球重力、地球重力、火星重力等。 Gravity refers to the gravitation of the Earth upon which the objects near the Earth’s surface are subjected. It is also slightly affected by the centrifugal force of inertia due to the rotation of the Earth. The same object experiences slightly different gravities at different latitudes and altitudes on Earth, The greater the gravity of the ground, the greater the force that any celestial body causes the object to land on the surface of the celestial body in a broad sense. For example: the moon gravity, Earth’s gravity, Mars gravity.
