Question

What is different about the motion of satellites that travel in elliptical paths compared to satellites that travel in circular paths?





a.


Elliptical satellites travel at a constant speed, but circular
satellites do not

c.


Elliptical satellites aren't acted on by gravity, but circular satellites are




b.


Elliptical satellites don't have a constant speed, but circular satellites do


d.


Elliptical satellites are much larger than circular satellites

Answer 1

In an elliptical orbit there is a rule which states that in equal periods of time the body in orbit will sweep out equal areas.

For a circular orbit this means constant speed.


If the time between 1&2 is the same as the time between 3&4, then the areas A1 and A2 will be equal

You can deduce the answer from this information
