Week 1 Inertial Frames of Reference & Galilean Transformations

Question 1

define an inertial frame of reference

Answer 1

frame of reference that moves with constant velocity relative to the absolute space frame

Question 2

define an event

Answer 2

something that happens in the universe

Question 3

what is the general coordinate form for spacetime

Answer 3

(x, y, z, t)

Question 4

what is the only thing we can assume about an event with spacetime coordinates in an arbitrary reference frame

Answer 4

the event is real

Question 5

what does Galilean transformations assume and what physics concept does it not work with

Answer 5

All observers in inertial frames will agree length of objects
This doesn’t work with special relativity
