Math Problem Statement

Calculate the gravitational force (Fg) between the Earth and the Moon using Newton's law of universal gravitation with given values.

Solution

The formula displayed is for calculating the gravitational force (FgF_g) between two masses using Newton's law of universal gravitation:

Fg=Gm1m2r2F_g = \frac{G \cdot m_1 \cdot m_2}{r^2}

where:

  • G=6.67×1011Nm2/kg2G = 6.67 \times 10^{-11} \, \text{Nm}^2/\text{kg}^2 is the gravitational constant,
  • m1=5.97×1024kgm_1 = 5.97 \times 10^{24} \, \text{kg} (mass of the Earth),
  • m2=7.35×1022kgm_2 = 7.35 \times 10^{22} \, \text{kg} (mass of the Moon),
  • r=3.84×108mr = 3.84 \times 10^8 \, \text{m} (distance between the Earth and the Moon).

Let's calculate it step-by-step.

  1. Compute Gm1m2G \cdot m_1 \cdot m_2: 6.67×1011×5.97×1024×7.35×10226.67 \times 10^{-11} \times 5.97 \times 10^{24} \times 7.35 \times 10^{22}

  2. Square the distance rr: (3.84×108)2(3.84 \times 10^8)^2

  3. Divide the results from step 1 by the result from step 2 to find FgF_g.
