this is prob a stupid question

[alias25]

is there a difference between decelaration and a deceleration force or are they just the same thing?

thanx(an don't laugh)

Deceleration is the common word for a negative acceleration. Physicists don't use it much because they are cool with negative numbers, so that negative- positive, it's all acceleration.

Deceleration force would be a force (of course). A force is different from an acceleration and they are related by Newton's law: force = mass X acceleration, or F = ma, as it's usually stated.

So if you tromp on the brakes, what your car is doing is decelerating, and that pull forward you feel is deceleration force.
