If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction is decreased by a factor of 9 (3 raised to the second power).

The mathematical formula for gravitational force is F=GMmr2 F = G Mm r 2 where G is the gravitational constant.

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

9 g

The 79,000 g is possible and correct for a low mass object like an individual dust particle that is circulating in a small radius of 0.004 meters in the narrowest part of the cyclone at 125 mph.

“The NHTSA standard for a sudden impact acceleration on a human that would cause severe injury or death is 75 g’s for a “50th percentile male”, 65 g’s for a “50th percentile female”, and 50 g’s for a “50th percentile child”.

Understanding g-force 100kph is 28m/s, 28 / 2.3 = 12m/s2, 12 / 9.8 = 1.2g.

The body is designed to pump blood upward, but negative gs force more of the blood to the head, causing vessels to burst in the eyes — a condition called “red out” — and, eventually, the brain. A extended force as low as negative 3 gs can prove fatal.

According to wikipedia, interstellar travel at 1G would take approximately 1 year + the distance in lightyears. Proxima Centauri (4.2 light years) for example would take 5.2 years. But that time is from the viewpoint of stationary observers at the departure point.

As of yet, no technology exists to neutralize the pull of gravity. The best way to approximate the feeling of weightlessness on Earth is to ride onboard a plane flying in parabolic arcs that mimic the shape of Saint Louis’s Gateway Arch.

Earth’s mass is variable, subject to both gain and loss due to the accretion of in-falling material, including micrometeorites and cosmic dust and the loss of hydrogen and helium gas, respectively. The combined effect is a net loss of material, estimated at 5.5×107 kg (5.4×104 long tons) per year.

In reality, the gravitational field is 9.7773 m/s² in Colombo compared to 9.7979 m/s² in Cape Canaveral, Florida (where SpaceX launches the Falcon Heavy from). Going the other way, the force of gravity acting on a rocket would be 0.215% less, meaning reduced fuel costs (theoretically).
