What happens when gravity on Earth halves?

In general, gravity can be defined as the force that pulls two objects together. It is the element that keeps the planets moving in orbit around the Sun and helps people not to fly out into space.

Every object with mass will have gravity. The bigger the volume, the stronger the gravitational force of that object. A large planet like Earth will pull you much stronger than a small object like a piece of cake.

Distance is also a factor to consider. The closer you are to an object, the more gravity you pull back. Meanwhile, the farther away the gravity is, the weaker it is.

Gravity on Earth is also uneven . According to NASA and data from the GRACE project, this force is slightly stronger in places with greater mass concentration on Earth. Even these focus points can change over time.

Reduced gravity can bring many health problems.

So what if gravity on Earth suddenly halved?It is difficult to pinpoint exactly, especially when what leads to this sudden change is more likely to cause other impacts. But considering the surrounding universe, we can make some predictions.

First, you can reduce a lot of weight. The reason is that the weight is actually unstable. This quantity varies according to position in the universe because it depends on how much you are gravitationally gravitational.

For example, if you weigh 100 Newton (N) on Earth, you will only weigh about 17 N on the Moon. The reason is that on the Moon, you only suffer 1/6 of the gravitational force on Earth. If gravity on the green planet is halved, you might be half as heavy as it used to be. It only happens when you survive and everything on Earth is normal.

However, reduced gravity can bring many health problems . The body is always working against gravity, muscles still have to 'deal with' this force even when you are standing still. The bones must support your weight, but the weight is under the influence of gravity. The heart must also resist gravity to pump blood throughout the body. With gravity and weight halved, the heart can become weaker, muscles become smaller, even bone mass decreases. These are problems astronauts encounter when in a weightless state.

So when you have half your weight, maybe the same things will happen, but to a lesser extent and on condition that everything else remains the same.

If gravity on Earth really suddenly only 1/2, many other forms will also change. One of them is the escape velocity . Because the gravity of the Earth is weaker, the accelerator or the velocity required to fly away from Earth will decrease.
