Which of these situations describes you observing from an inertial reference frame?
a. you are in the car of a train, seated at a table, and the train suddenly slows down
b. you are in the car of a train, going north, and the train goes around a curve to go west
c. you are in the car of a train, and the train is going up a steep hill at a steady speed
d. you are on a ride that spins riders around a horizontal circle
The Attempt at a Solution
I read that inertial reference frames are those that are not accelerating. I still do not understand this completely. I think the answer for this question is c, since you would be moving with the train at a constant velocity.
