You can just say "decelerate".
- lolinder 4y agoUnless what they meant is "stop accelerating quite so much" and not "slow down".
- leephillips 4y agoThat’s what I meant.
- HeyLaughingBoy 4y agoBoth are examples of deceleration, but in the latter case, the vector is in a different direction. [edit] Apparently I'm wrong. All the definitions of deceleration I can find are actually negative acceleration.
- sokoloff 4y agoThe next four derivatives after acceleration are jerk, snap*, crackle, and pop, respectively. (What you were describing is negative jerk.) * snap is equivalently called jounce.
- leephillips 4y agoIt’s not the same. To decelerate is to have d^2c/dt^2 < 0 (where c is the career measure). To de-accelerate is to reduce d^2c/dt^2 while d^2c/dt^2 remains > 0 (in other words, to make d^3/dt^3 < 0).
