Actually, gravity is an attraction. The theory goes that all matter attracts other matter. The big question is, "What part (particle) of an atom is the one responsible for this attraction (gravity)?" This is one of the mysteries that physicists are trying to solve in high-energy particle collisions. They are hoping to smash atomic particles together at such high speeds, with enough force to break them up into the most basic pieces possible. We suspect that some very basic particle-like the Higgs boson-may be the one that causes this attraction we call gravity.

gravity is the force
the force of gravity.
Yes, it is not a constant. The force of gravity is related to the distance from the centre of the earth so that the force of gravity will be slightly reduced at altitudes. Also, the earth is not a perfect sphere - it bulges at the equator and is flatter at the poles. So the force of gravity will be greater at the poles. The force of gravity is also affected by what is under the surface: if standing over dense rocks, the force will be greater. Finally, the force of gravity is also higher after heavy rainfall. [I guess that is because the water fills up all the air gaps in the soil and so increases its density.]
Of course it does.
Any force can. You "oppose" gravity every time you get out of bed and stand up, and every time you use the force of your leg muscles to walk upstairs.
There are many types of forces that oppose motion such as friction, drag and most universal, gravity.
When a force is present to oppose that of gravity. eg > Upthrust on a body in a liquid (body in a swimming pool) Centripetal force ( orbiting satellite or space station)
Gravity is a force.
The earth's gravitational pull makes objects sink in a liquid, but buoyancy acts in the opposite direction to oppose the gravity. Whether an object sinks or floats depends on which force is bigger. ================================
what is the force of gravity on mecury
Gravity is a force but has no mass.
gravity not as a force, but as the curvature of spacetime
load force and friction oppose the effort force
Frictional force
No gravity is the weakest force. The proper order is strong force, Electromagnetic, weak force, then gravity
Lift is the upward force that opposes the force of gravity.
