Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity.
There are four fundamental forces at work in the universe: the strong force, the weak force, the electromagnetic force, and the gravitational force. They work over different ranges and have different strengths. Gravity is the weakest but it has an infinite range.
Earth’s Gravity is strongest on the ground, usually at sea level, and weaker as you move away from the core, eg the peak of Mt. Everest. The gravity at the poles is stronger than the equator, partly because the obloid earth is slightly wider, but only by a small ratio.
Although the researchers found no signs of a fifth force, they did determine a new limit, 10 times stricter than before, on how strong such a force could be. The NIST team believes that their innovative experimental setup will allow them to make even more precise measurements in the future.
Contrary to popular belief, there’s no such thing as zero gravity. The earth’s gravity keeps the moon in orbit. And astronauts are generally much closer to earth than the moon is, which means that the earth’s pull on them has to be much stronger.
Inside a spherical shell, there is no change in potential as one moves inside, and since only a change in potential implies a force there is no force. Hence the acceleration due to gravity is zero at the centre of the Earth.
But new evidence suggests the existence of a fifth force of nature, which could open a whole new understanding of the laws of physics. The forces currently known to scientists are gravity, electromagnetism, the weak force and the strong force.
Physicists May Have Discovered ‘New Force of Nature’ in LHC Experiment. The Large Hadron Collider (LHC) sparked worldwide excitement in March as particle physicists reported tantalizing evidence for new physics – potentially a new force of nature.
We know of four fundamental forces of nature, with no signs of a fifth. But dark matter and dark energy make up over 90% of all the contents of the universe.
In physics, there are four observed fundamental interactions (also known as fundamental forces) that form the basis of all known interactions in nature: gravitational, electromagnetic, strong nuclear, and weak nuclear forces. The characteristics of this fifth force depend on the hypothesis being advanced.
It might seem like a fantasy to float weightlessly through the air but practically, the human body would go through negative change, such as muscle and bone atrophy while living in zero gravity. Even the rivers, lakes and oceans on Earth wouldn’t stand in zero gravity, without which humans cannot survive.
No. The attractive force called gravity does not extend beyond galaxy groups. As you get farther away from a gravitational body such as the sun or the earth (i.e. as your distance r increases), its gravitational effect on you weakens but never goes completely away, at least according to Newton’s law of gravity.

It is a common misconception that astronauts in orbit are weightless because they have flown high enough to escape the Earth’s gravity. In fact, at an altitude of 400 kilometres (250 mi), equivalent to a typical orbit of the ISS, gravity is still nearly 90% as strong as at the Earth’s surface.
