Hmm. Thanks for the quick replies. I like the explanation that the net radial acceleration is zero, as for every radial acceleration, there is an opposite equal in magnitude acceleration. Is there another way of explaining this, perhaps?
Hi all. The answer to this might be trivial. If it is, sorry for posting. If you calculate the acceleration due to gravity of an orbiting satellite, it could be around 8.5-9.5m.s-2, depending. So, it's tangential velocity is such that as it falls towards earth, Earth curves away and the...
I'm a Physical Science teacher in South Africa. Been a teacher now for 5 years. Love science, especially Physical Science. Love to teach it, always a challenge - you keep learning! Always got questions, so expect those from me. Glad to be on this forum. Cheers, Chris
