What is the acceleration due to gravity?

टिप्पणी लिखिए

उत्तर

According to Newton’s second law of motion, a force acting on a body results in its acceleration. Thus, the gravitational force due to the earth on a body results in its acceleration. This is called acceleration due to gravity and is denoted by ‘g’.
