Comment by BDPW 4 days ago You're conflating coordinate and proper acceleration. 2 comments BDPW Reply marcus_holmes 4 days ago I don't think I understand the difference. I have always been told that acceleration is change in velocity over time. Is that wrong? Are there other types of acceleration? magicalhippo 4 days ago > I have always been told that acceleration is change in velocity over time. Is that wrong?Not per se, but it's more complicated when relativity gets involved.Wikipedia has some decent starting points:https://en.wikipedia.org/wiki/Proper_velocityhttps://en.wikipedia.org/wiki/Proper_accelerationhttps://en.wikipedia.org/wiki/Four-acceleration

Not per se, but it's more complicated when relativity gets involved.
