Estimate the maximum centripetal acceleration of the moon around the sun. For this estimate, you may assume that the earth and moon are both and circular orbits around their parent body.

Estimate the maximum centripetal acceleration of the moon around the sun For this estimate you may assume that the earth and moon are both and circular orbits a class=

Respuesta :

Using Newton's second law and the universal gravitation law we find that the maximum acceleration response is

  • the acceleration around the sun is twice the acceleration around the Earth
  • Acceleration around the Sun 6 10⁻³ m/s²
  • Acceleration around the Earth 3 10⁻³ m/s²

The universal law of Gravitation states that the force between two bodies is proportional to their masses and inversely proportional to the square of their distance

           F = [tex]G \frac{M m}{r^2}[/tex]  

Where G is the universal gravitation constant (G = 6.67 10-11 N m²/kg²), M and m the mass of the bodies and r the distance between them

Newton's second law indicates that the force is proportional to the masses and the acceleration of the bodies

        F = m a

Where F is the force, m and a the mass and acceleration of the body     

let's substitute

         [tex]G \frac{Mm}{r^2}[/tex]  = m a

         a = [tex]G \frac{M}{r^2}[/tex]

In this case the acceleration is called centripetal since it corresponds to a circular motion of the Moon and the Earth.

In tables we can find the values:

  • The mass of the Earth is 5.98 10²⁴ kg
  • The distance between the Moon and the Earth is 3.84 10⁸ m
  • Mass of the sun 1,991 10³⁰ kg
  • Earth - Sun Distance 1,496 10¹¹m

Let's calculate the acceleration of the Moon around the Earth

      a₁ = 6.67 10⁻¹¹ [tex]\frac{5.98 \ 10^{24}}{ (3.84 \ 10^8 )^2 }[/tex]

      a₁ = 2.71 10⁻³ m / s²

The acceleration of the Earth around the Sun  

      a₂ = 6.67 10⁻¹¹  [tex]\frac{1.991 \ 10^{30} }{(1.496 \ 10^{11})^2 }[/tex]  

      a₂ = 5.93 10⁻³ m / s²

We can see that the acceleration around the Sun is twice the acceleration of the moon around the Earth

In conclusion they use Newton's second law and the universal gravitation law, we find that the maximum acceleration response is

  • the acceleration around the sun is twice the acceleration around the Earth
  • Acceleration around the Sun     6 10°³ m/s²
  • Aacceleration around the Earth 3 10°³ m/s²
