Well, if you drop something made of glass or china from a height, gravity pulls it down an dit is likely to brake.
It also makes travelling up hill tricky and makes objects heavy to carry.
And lastlly, it stops humans flying ;)
Yes, there can be negative gravity. If a gravity is a pulling force then in the other hands a negative gravity would be a pushing force, in other words, the negative gravity would push us to wherever and the positive gravity on Earth would pull us.
The normal reaction to gravity is attraction. Gravity tries to pull the two objects closer together. A negative reaction would be that the two objects try to push apart. Sounds like science fiction.
because gravity is a force that acts down on an object. In physics up is positive and down is negative
A positive tropism is something that bends with gravity or bends towards the light or the roots grow towards water. A negative tropism does the exact opposite.
Retardation is the application of a force that produces negative accelleration. Synonyms would be braking, decelleration, damping, etc. Gravitational force operates downward (in a negative direction) so, in most frames of reference, gravity is a retarding force.

No, according to Newton's laws, the force of gravity cannot be negative.
No
"Negative gravity" is not a scientific concept. Gravity is a fundamental force of attraction between masses. "Positive gravity" is simply the normal gravitational force experienced on Earth, pulling objects towards the center of the planet.
The gravity value is always positive when an object falls to the ground. Gravity is an attractive force that pulls objects toward the center of the Earth, causing them to accelerate downwards.

Gravitational potential energy is negative because it is defined as the work done by gravity when an object moves from an infinite distance away to a certain point in a gravitational field. The negative sign indicates that work is done by gravity on the object as it moves closer to the source of gravity.
The normal reaction to gravity is attraction. Gravity tries to pull the two objects closer together. A negative reaction would be that the two objects try to push apart. Sounds like science fiction.
A reversal in Earth's gravity from positive to negative could have catastrophic consequences. It could lead to mass destruction of infrastructure, loss of life, and disruption of ecosystems. The change in gravity would affect everything on Earth, causing chaos and instability.

You can use positive acceleration due to gravity when an object is moving in the direction of the gravitational force, like when it is falling towards the ground. Negative acceleration due to gravity is used when an object is moving opposite to the direction of the gravitational force, like when it is moving upwards against gravity.
No, gravity is not inside us. Gravity is a force that acts around us. Everything in the universe has gravity. I am not sure about stars that weigh negative (e.g -500g) I guess that they would have a reppling force.
