Ugh.. Is it work?
"What is typically the equal force acting against gravity that pulls is down and keeps us seated"
Isn't only gravity the only force pulling us down to Earth's mass? |

Tried that, got "work"
I didn't get a valid reason though... |

| Momentum? Hm.. I don't think so.. Could it be weight? Ugh.. |

Mass? Weight? Work? Buoyancy? (maybe) |

It could be weight...
"Weight is the measurement of the pull of gravity on an object" |

Inertia-
The tendency of an object to resist changes in it's current velocity; Whether in motion or motionless. or The property that keeps an object from doing what it's desiring to do...
So, hm... Force that pulls us down and keeps us seated, possibly.. |

The answer is normal force. Look it up, I did this recently
Doktor, i can haz an interwebz? |

| I'm fairly sure this is a non-contact force.. School is a bit tough too, science test tomorrow, that's why I'm studying questions I recieved a couple of days ago. |

It's not centripetal force..
Centripetal force can be demonstrated by a string tied onto a small object and see how the it goes towards the centre. |

| The opposing vector of any force is called the normal force, so you could say that, but likely compression - of your body, the ground, or whatever you're sitting/lying on - could be the answer, and that is mediated by the electromagnetic force, so.. Say that if you want to sound smart. |

I hope you read this in time. This is centrifugal force. The question itself is confusing just because Gravity IS the force that pulls down and keeps us seated. However, to the question "what is typically the equal force acting against gravity", the answer is centrifugal force. Think of a washing machine. If you've ever went to the laundromat or looked inside your own, you would have noticed that the water and the clothes stick to the outside of the washer as they spin around because they are getting thrown by centrifugal force. The answer cannot be mass because mass is a physical property of matter and works with gravity creating weight. Because of gravity, there is weight created by mass. On Earth I weigh 145 pounds because of the way gravity pulls on my mass and on the moon I weigh 24 pounds because of the moons lower gravity. Furthermore, the moon's gravity is different from the earth's gravity because of the two object's mass. The more there is, the more gravity. There's a lot of detail to this but that's the general concept. Therefore, if gravity is what pulls us down, centrifugal force must be the force the pushes us outwards because the Earth is spinning. If there was no gravity, we would all fly out into space. If you've ever gotten a baseball wet and thrown it, you can see the water flinging off. I hope this answers your question. |
