Force of gravity from different heights

Click For Summary
SUMMARY

The discussion focuses on calculating the gravitational force acting on an object dropped from various heights: 1 km, 10 km, and 100 km. The gravitational force can be determined using the formula F = (-G x m1 x m2) / r^2, where G is the gravitational constant (6.7 x 10^-11 N(m/kg)^2), m1 is the mass of the object, m2 is the mass of the celestial body (e.g., Earth or the Moon), and r is the distance from the center of the celestial body to the object. The impact of height on gravitational pull is significant, as the distance r changes with elevation, affecting the force experienced by the object.

PREREQUISITES
  • Understanding of Newton's law of universal gravitation
  • Familiarity with gravitational constant (6.7 x 10^-11 N(m/kg)^2)
  • Basic knowledge of mass and distance measurements in physics
  • Ability to manipulate algebraic equations
NEXT STEPS
  • Research the effects of altitude on gravitational force using the formula F = (-G x m1 x m2) / r^2
  • Explore gravitational variations on different celestial bodies, such as the Moon and Mars
  • Learn about the implications of gravitational pull on satellite orbits
  • Investigate the concept of weightlessness at high altitudes and its relation to gravity
USEFUL FOR

Students of physics, aerospace engineers, and anyone interested in gravitational effects and celestial mechanics will benefit from this discussion.

How do I find the difference in gravity pull on a object dropped from 1km, 10km and 100km based on the objects mass (such as Earth vs the moon)

e: Don't care about drag
 
Physics news on Phys.org
You can use the equation:

F = (-G x m1 x m2) / r^2

F is Force
G is Gravitational constant (6.7x10^-11) (Make it negative to show attraction)
m1 is the mass in kg of an object
m2 is the mass in kg of another object
r is the radius or the distance in meters between the objects.

Hope this helps!
