The physical meaning of G = g / M Like the gravity per kilogram?
Almost, it's the ratio of gravity to mass. It's a fixed value, equal to 9.8n/kg, which can be calculated as 10 without requiring accuracy

Flying man in the air, when one person and then another person's hand swing to the highest point (the lower body is still perpendicular to the horizontal plane), the lower part of the lower person from the ground is marked as o point. At this time, the two people let go and asked, does that person fall at o point, or to the right or left of o point? PS: now there are two kinds of disputes, one is on the o point, the other is on the left side of o point. Please express your opinions and explain the reasons!
