Can their be negative gravity?
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.
What is a negative response to 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.
Why is gravitational potential always negative?
because gravity is a force that acts down on an object. In physics up is positive and down is negative
What is a positive and negative tropisms?
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.
What is retardation in physics?
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.
