Question

Estimate the force that the Moon exerts on you when it is directly overhead.(You will need some data to answer this question, I suggest Googling the basic facts.) Briefly explain your process. Try to use words rather than equations in your explanation, but be sure to give a numerical estimate when you are done. (Note that in the image, the Earth and Moon are to scale, but they are WAY too close. In reality, the distance between the two is 30 times the diameter of the Earth!)

" apply Newton graitional law to solve the problem
the force between the two masses is F=G m1 m2 /r^2
here m1 is mass of the person, m2 is mass of the moon and r is is distance between the person and the moon
let mass of the person as 62 kg
F= 6.67*10^-11(62)(7.34767309*10^22kg)/30(12756.2*10^3m)^2
= 0.0020748 N "

4) Re-state the answer you got to the previous question. Now estimate the force you exert on the Moon when it is directly overhead. Explain how you got your answer.

Explanation / Answer

d = distance between moon + radius of moon

F= 6.67*10^-11(62)(7.34767309*10^22kg)/(384400000+1737000)^2 = 2.038*10^-3 N

4) Using newton's third law of motion

every action has equal and opposite reaction

force exerted by us will be the same= 2.038*10^-3 N
