Negative-g force is the downward acceleration that produces weight force in the upward direction.
For example on a roller coaster, when the acceleration of our body increases more than the free-fall acceleration, we experience an upward force and get a sense of weightlessness due to this negative-g force.
This negative-g force is also experienced by pilots while high speed dives.
In simple terms, the positive-g force pushes you downwards into the seat while the negative-g force pulls you upwards out of the seat.
Negative G force, also known as negative gravity or inverse gravity, is a term used to describe a situation in which an object or person experiences a force that is opposite to the direction of the gravitational pull of the Earth. This is different from the normal gravitational force that we experience, which pulls objects and people toward the center of the Earth. In a situation with negative G force, an object or person would be pushed away from the center of the Earth.
Negative G force can be experienced in a number of different ways, including during certain types of acceleration, such as when an aircraft is taking off or when a car is speeding up quickly. It can also be experienced in other situations, such as when a person is upside down on a roller coaster or when a person is in freefall.
One of the main effects of negative G force is that it can cause a person to feel weightless. This is because the force of gravity is not acting on the body in the same way as it normally would. This can cause a number of physiological effects, including changes in blood pressure and an increased heart rate.
Negative G force can also have an effect on the objects and materials around a person experiencing it. For example, if a person is in an aircraft experiencing negative G force, objects in the aircraft may start to float or drift in the direction opposite to the gravitational pull of the Earth. This can be disorienting and even dangerous, as loose objects can potentially become projectiles and cause harm to people or damage to the aircraft.
In addition to the physiological effects and the effects on objects, negative G force can also have an impact on a person’s sense of balance and spatial orientation. This can make it difficult for a person to move or maintain their balance, and can also cause disorientation and dizziness.
Overall, negative G force is a phenomenon that occurs when an object or person experiences a force that is opposite to the direction of the gravitational pull of the Earth. It can cause a number of different effects, including changes in blood pressure and heart rate, the feeling of weightlessness, and disorientation and dizziness. While it can be exciting and fun to experience in some situations, it can also be dangerous and should be carefully controlled and monitored.
