The formula for calculating the force opposing gravity in orbital simulations is F = G * (m1 * m2) / r^2, where F is the force opposing gravity, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between the two objects.
The force opposing gravity acts as a centripetal force, keeping the object in orbit by balancing out the gravitational force exerted by the larger object. Without this force, the object would either escape the orbit or crash into the larger object.
The mass of an object can be determined through measurements or calculations based on the object's density and volume. In orbital simulations, the mass is often assumed or given as a known value.
Yes, the force opposing gravity can change if the distance between the two objects changes, or if there are other forces acting on the objects such as atmospheric drag or the gravitational pull of other objects.
The force opposing gravity is a key factor in predicting satellite orbits, as it helps determine the velocity and trajectory of the satellite. By accurately calculating this force, scientists can predict the path of a satellite and ensure it stays in orbit around a larger object, such as Earth.
