1. The problem statement, all variables and given/known data A satellite orbiting the Earth moves to an orbit which is closer to the earth. What happens to the speed and the time it takes for the one orbit of the Earth. 2. Relevant equations It is circular motion so I will use a=ω^2(r) a=(2π/T)^2/r 3. The attempt at a solution If the r is decreasing, then the value of a is also decreasing this means that period will increase as it is inversely proportional. Can someone help me out?
