Q: Have fractional order differential models been explored as an alternative to standard gravitational field theory?

docscienceSince Einstein introduced his field equations and general theory of relativity, experimental evidence, at least on the cosmic scale has repeatedly supported the theory. Nevertheless, many seeking to extend the theory (Grand theories that combine relativity and quantum mechanics) or to explain gap...

hmm...
stochastic GR anyone

Hello! I got a simple physics question
In a review at class it asked me "Which of the following is the condition for static equilibrium? Select all apply."
A) Position = 0
B) Velocity = 0
C) Net Force = 0
D) Net Torque = 0
I said Velocity = 0, Netforce = 0, and Net torque =0. But i got that wrong. Does it mean position =0 ? If so why?

Well position being zero doesn't really make sense since you're free to choose how you define your position. I'd probably normally say velocity is zero for equilibrium, but you have a similar choice of inertial frame so you can just choose a frame where the velocity is zero provided that forces balance

@danielunderwood Nvm, it was only Netforce =0 and Net torque = 0. Thankfully i got it! Thanks for the help! :)
