  Alright so anyone who has taken physics might understand this, or they might not. Anyways bear with me here. My physics teacher changes her answers depending on the day of the week, one day gravity is there and the next its like "Gravity? Whats gravity?" Its ridiculous for real I`m not kidding I swear D:
  
  Anyone other than me had this problem I cant be the only one right?
  :gloom:
  
  Please share if you understand this pain. :P

  Wait what? How can the Physics teacher suddenly decide if gravity is not there? That's really weird and confusing. Gravity as a force is always there, planets, stars, they all have a gravitational pull. It's what keeps the earth in orbit around the sun and what keeps us from flying out into space.

  can physics even exist with out gravity ?

  It can splat. There are other forces at the atomic and subatomic levels that do things gravity isn't strong enough to handle.
  
  Just where most of the atomic and subatomic forces only produce significant amounts of force over extremely close distances or require large quantities of matter to generate significant force, gravity is able to pull a cloud of loose atoms together into a solid mass given enough time.

  Gravity is an amazing mindfuck.
  
  How old is your phyiscs teacher?
  
  Kind hard to tell the details though from a weird, vague, hypothetical example like that.

  I dunno shes just kinda crazy and I would say that she is late 40s early 50s? Also I know gravity has to exist that was a bit of a hyperbole but still. xD She does similar things and its a bit crazy.

  Why exactly does gravity have to exist?
  
  Current theory just assumes gravity exists because we can observe its influence. We don't know how it actually works beyond that it is related to an object's mass.
  
  Without it though, the cosmos as we know it would not exist. Gravity was the force responsible for matter clumping up the way it does to form the solar system and planet we live on.

  Depending on the difficulty level of your physics course and how far along you are in it, the question will usually begin or end with "Neglecting ____ force." If it doesn't say anything and your course focuses on building on one topic after the other, you're probably expected to factor in gravity, air resistance, friction, torque, electromagnetism and god knows what else...
  
  But yeah I had a teacher like that. She expected everyone to already know where and when the forces of nature did and didn't apply, but then again, there's a reason AP physics is rumored to be the most difficult class in high school and why physicists are considered gods among men.

  Well she actually has only degrees in geology so it is a bit weird that she is teaching this class...
