wtf are even leo and geo satelites like what do we need to know abt them i dont even think i learned that
Its Mod 5 content regarding gravitational stuff. LEO is low earth orbit satellites (closer from centre of earth and orbits earth like twice a day or smthg) and GEO is geostationary satellites (further from centre of earth and synchronised with earths motion)

lmao leos do Not orbit that slowly, they orbit every 90 mins

guys u think they will ask smth about kepler laws other then using the formula from the last law? i havent seen a single question about it

Do you guys think we'd need to know how a cyclotron and synchrotron work in detail? I know particle accelerators are in the syllabus but don't really know the extent to which they can be assessed

dont think so but its good to know i think u should def know the importance of particle accelerators tho

really??? bro that is essential to planetary motion lol, u mean r^3/T^2 = GM/4pi^2 right? They can ask this in a graphical format for u to find the mass or something like that definitely.

no i said “other then using the formula” at the end. Im talking bout the other laws 😭😭😭

wait so just confirming the other laws are all planets orbit in an elliptical shape, the time it takes for the planet to cover one area on the other side of orbit is the same as the time it takes for it to cover another area on the other side of orbit, and KE is down and PE is up near the perigee, and KE is up and PE is down near the apogee? I think that is all we gotta know for the other laws or facts.

yes u should also mention elliptical orbits have two focal points where sun occupies among one of them

perigee is closest point so it makes sense KE is up and not PE
