What is the main goal of a reference frame?
What is the main goal of a reference frame?
- To establish the laws of motion for celestial bodies
- To define the absolute position of a point in space
- To determine the exact time of an event
- To create a measurable relationship between different physical bodies (correct)
What is the primary difference between reference frames and reference systems?
What is the primary difference between reference frames and reference systems?
- Reference frames are fixed, while reference systems are inertial
- Reference frames are realized from physical bodies, while reference systems involve prescriptions and conventions to define axes and coordinates (correct)
- Reference frames are based on Newtonian physics, while reference systems are based on Einstein's theory of relativity
- Reference frames are used for space navigation, while reference systems are used for terrestrial navigation
What is a Terrestrial Reference System (TRS)?
What is a Terrestrial Reference System (TRS)?
- A system for measuring the absolute position of celestial bodies
- A system for determining the time of tectonic or tidal deformations
- A spatial reference system co-rotating with the Earth in its diurnal motion in space (correct)
- A reference system anchored to the International Space Station (ISS)
