The weight of the body is equal to the force of gravity when the body is at rest or in uniform rectilinear motion.
If the acceleration of the body a, directed vertically upwards, then the body weight will increase and be determined by the formula: P = m * (g + a).
If the acceleration of the body a is directed vertically downward, then the body weight will decrease and be determined by the formula: P = m * (g – a).
