  • Q6

    This law states that "every point mass attracts every single other point mass by a force acting along the line intersecting both points. The force is proportional to the product of the two masses and inversely proportional to the square of the distance between them."

    Law of Universal Attraction

    Law of Universal Gravitation

    Law of Celestial Gravitation

    Law of Acceleration

  • Q7

    How do you interpret the part�"the force is�proportional�to the�product�of the two masses and�inversely proportional�to the�square�of the distance between them" into a mathematical formula?

    F\ =\ \frac{Gr^2}{M_1M_2}

    F\ =\ \frac{M_1M_2}{r^2}

    F\ =\ \frac{r^2}{GM_1M_2}

    F\ =\ \frac{GM_1M_2}{r^2}
