I got centripetal and reactant force. This is because if there was only gravity it would fall straight downyeah fam

Are you sure? It said stable orbit so I thought that implied it was undergoing centripetal force due to gravity with a constant speedI got centripetal and reactant force. This is because if there was only gravity it would fall straight down
nah the satellite is kept in place by its velocity not a counter force, centrifugal force is a pseudo force resulting from trying to explain the inertia of objects in a non inertial frameI got centripetal and reactant force. This is because if there was only gravity it would fall straight down
Theres a reaction force for everything so... Anyways its too early lets relax and waitnah the satellite is kept in place by its velocity not a counter force, centrifugal force is a pseudo force resulting from trying to explain the inertia of objects in a non inertial frame
Dont underestimate physics HSC marking.It was alright. It was just that question hahahha. I know for sure I got more than 75%. Really hoping for mid 80%. Some of the multiple choice was definitely iffy. I thought it was harder than previous tests though
the reaction force is the gravity of the satellite acting on the planet, however because its mass is so small, the effect is negligibleTheres a reaction force for everything so... Anyways its too early lets relax and wait
If you don't have it, why do you expect other people to? Yeah teachers have it, but I don't think their priority is uploading a hsc paper for you which won't at all change your mark.is anyone gonna upload the paper so we can get mc solutions or nah
relax haha, happened for eco so i assumed people might do it here tooIf you don't have it, why do you expect other people to? Yeah teachers have it, but I don't think their priority is uploading a hsc paper for you which won't at all change your mark.
Air resistance....Nope there is no reaction force on things which are falling
At an altitude of 36000 km? (Geostationary) For our course it would be called negligible.Air resistance....
I thought of it in regards to projectile motion because I read of an example where they say the rocket used to launch a satellite into space will not make it a projectile (since it's being propelled with the constant thrust force) BUT when it runs out of fuel then it becomes a projectile --> As we all know the only force acting on a projectile is gravity so yeahAir resistance....
Atmosphere only extends for about 200 - 400 km about the earths surface so it's more likely to affect a low earth orbit satelliteAir resistance....
lol woops threw my copy away with all the rest of my HSC stuff. I think Fizzy_Cyst might upload it if he manages to get a paper.is anyone gonna upload the paper so we can get mc solutions or nah
