Two crocodiles fly, one green, the other to the left, how much weighs 1 kg of apples if the shadows disappear at midnight?? to
yyy: The weight in the inertial system of reference P coincides with the force of gravity and is proportional to the mass m and the acceleration of free fall g at a given point.
Thus, in a state of rest, 1 kg of apple will weigh under conditions of acceleration of free fall equal to 9.81 m/s^2 on the planet Earth (approximately):
P = m*g = 1 [kg] * 9.81 [m/s^2] = 9.81 [N] (Newton)
