An astronaut weighing 259 lbs on earth is on a mission to the moon and mars. (a) what would he weigh in newtons when he is on the moon? the acceleration due to gravity on the moon is one-sixth that on earth. 0.043 incorrect: your answer is incorrect. seenkey 192 weight is the gravitational force exerted on an object. recall the formula for weight and the quantities it depends on. which quantity is the same on the earth as on the moon? which quantity changes on the moon? also note your answer should be in newtons. n (b) how much would he weigh in newtons when he is on mars, where the acceleration due to gravity is 0.38 times that on earth? n (c) what is his mass in kilograms on earth? kg
