ensabah6 said:How do I calculate the strength of gravity between two objects say that 2 years ago were 2 light years apart, during which they became 0.5 light years closer, if during those two light years, the stars lost 50% mass due to fusion and light,
based on their mass "now", or based on how much mass they had 2 years ago,
The strength of gravity over light years is calculated using the equation F = G * (m1 * m2)/r^2, where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between them.
Yes, gravity weakens over long distances due to the inverse square law, which states that the force of gravity is inversely proportional to the square of the distance between two objects. This means that as the distance between two objects increases, the force of gravity between them decreases.
The strength of gravity is directly proportional to the masses of the two objects. This means that as the mass of one or both objects increases, the force of gravity between them also increases.
No, gravity cannot be measured over light years as it is not a constant force and can vary depending on the masses and distances of the objects involved. However, the effects of gravity can be observed and calculated over long distances using mathematical equations and astronomical observations.
The strength of gravity over light years affects the movement of objects by influencing their trajectories and causing them to orbit around each other. The stronger the force of gravity, the more significant its impact on the movement of objects over vast distances.
