Question

ars nly shrank to a tenth mass What would o the Sun? d sphere to a and mass How where G-untversal gravitational constant: G-6.67x101 N k m-3 kg- the mass of the baby M-either the mass of Mars or the obstetrician, and r-the separation between the baby and either Mars or the doctor at the instant of birth th bored from one of the Earth, and seball down this e surface What Questions 1. Calculate Fr. the force on the baby due to Mars. Mars has a mass M,-6.23x102kg, and when it is at opposition, it is at r 3.78x10"m distance. the ball 2. Calculate F2. the force on the baby due to the doctor. A reasonable mass would be M2-65 kg, and the distance would be small, r2Im I the resulting 3 What has a greater gravitational influence on the infant. the presence of Mars or the presence of the doctor (And that) emselves as redictions as Calculating the Mass of the Earth The weight of an object is literally the measurement of the gravitational force exerted on it by the Earth. If you know how much an object weighs, you know the force on it. Newton's Third Law of Motion tells us that we also know exactly how much force is being exerted on the Earth by the object as wel planets on a Tep Synergy ww.pynce [email protected] Rearrange Newton's Law of Gravity, solving the equation for the Mass of the Earth: FR M,- GM where Me-mass of the Earth, F-gravitational force between the object and Earth, Re-separation of masses, radius of the Earth, R,-6.38x 10 m G-universal gravitational constant: G-6.67x10-1 Nm kg M-mass of the object attracted to the Earth. Procedure and Questions Using a scale that measures force in Newtons (N), weigh an object with a known mass. Record both the mass (M) and the weight (F) of the 1. 2. object Calculate the mass of the Earth (Me) using the above equation. How accurate is your result? The accepted value for the mass of the Earth is Me= 5.98x1024kg. Calculate the 3. nce. percent error in your value. accepted M, - your M accepted M y is born late the co the x 100 % error=
