Hello, I have here a question which seems very important, I have a test in 2 days and just need some help on understanding this experiment which these questions are based off of.
It starts off with this:
A spacecraft is initially at rest on the surface of the Earth. It then accelerates away from Earth into a deep space where it then moves with constant velocity. There is a spring balance supporting a mass from the ceiling.
Then it shows these three pictures:

And three questions ask:
Identify and explain, in each case, the motion of the spacecraft that could give rise to the reading shown.
1. At rest on the Earth's surface
2. Moving away from Earth with acceleration.
3. Moving with constant velocity in deep space.
I just need some kind of starting point as to how to read the 3 diagrams...I don't understand how to answer these questions at all cause I am not sure what it is asking me to do. Any help is greatly appreciated, thank you
