# Consider a satellite in uniform circular orbit around the Earth, and then consider

## Homework Statement

Question is in attachment
Can someone explain to me what the infinity sign is I'm new to this topic.

All I know is that as a satellite goes to a higher orbit that the velocity decreases.

It looks like that "infinity" sign is really a greek letter omega, "ω". It is the symbol used for angular velocity when given in terms of radians.

Oh ok. The only knowledge i have of angular velocity is it determines how fast something is turning. So wouldn't the angular velocity be proportional to the velocity and since the satellite is going to a higher orbital, the speed would thus decrease and so if angular velocity is decreasing, wouldn't the velocity be decreasing as well? =}
