Unit Activity Unit: Polynomials This activity will help you meet these educational goals: Mathematical Practices—You will make sense of problems and solve them, reason abstractly and quantitatively, use mathematics to model real-world situations, and look for and express regularity in repeated reasoning . Introduction In this unit, you learned about number systems and polynomials. You also learned how to write equations and rearrange them to answer questions. In this unit activity, you will write equations and rearrange them to answer questions and explain concepts about closure pertaining to number systems and polynomials. __________________________________________________________________________ Directions and Analysis Task 1: The Force of Gravity 1 © 2015 EDMENTUM, INC.

The force of gravity, F , exerted between two objects is equal to the product of the gravitational constant, G , the mass of the first object, m 1 , and the mass of the second object, m 2 , divided by the square of the distance between their centers, d . This is often used to determine the gravitational attraction between two massive bodies, such as planets, in space. a. Write the formula for F described in the situation above. Type your response here: F =G m m / R ² b. If you were a physicist trying to determine the gravitational constant and you were able to measure the force of gravity exerted between two objects, their masses, and the distance between their centers, how would you rewrite this formula? Type your response here : G=FD^2/(M1M2) c. When the center of Earth is 2 × 10 11 meters from the center of Mars, the force of gravity between the two planets is about 64.32 × 10 14 newtons. The mass of Earth is

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
