How to find the force exerted on a particle on the Earth by the Sun

Click For Summary
SUMMARY

The force exerted on a particle on Earth by the Sun can be calculated using the formula F = - GMm/r², where G is the gravitational constant, M is the mass of the Sun, m is the mass of the particle, and r is the distance between the Sun and the particle. In this scenario, the mass used for m should be that of the pebble, as the force is specifically the gravitational pull exerted by the Sun on the pebble. This clarification is crucial for accurately solving the problem.

PREREQUISITES
  • Understanding of Newton's law of universal gravitation
  • Familiarity with gravitational constant (G)
  • Knowledge of mass and distance in gravitational equations
  • Basic algebra for manipulating equations
NEXT STEPS
  • Research the value of the gravitational constant (G) and its significance in calculations
  • Learn about the mass of the Sun and its role in gravitational force calculations
  • Explore the concept of gravitational force in different contexts, such as planetary motion
  • Study how to apply Newton's laws to various celestial bodies
USEFUL FOR

Students studying physics, particularly those focusing on gravitational forces and celestial mechanics, as well as educators looking for examples of gravitational calculations.

Homework Statement


Find the force exerted on a particle on the Earth by the sun.

Homework Equations


F = - GMm/r2

r = distance between sun and particle
M = mass of sun
G = Gravitational constant
m = ?

The Attempt at a Solution


Should I be using the other mass as that of the earth, or that of a pebble? I think it is the pebble. I mean it's the force BY the sun ON the pebble, but I want to make sure.

Yes, in this case you should use the mass of the pebble
