Question

what is negative accelartion​

Answer 1

Answer:

It only means acceleration in the negative direction. If the velocity is said to be in the positive direction, negative acceleration would indicate that the object is slowing down. But if the velocity is said to be in the negative direction, negative acceleration would indicate that the object is speeding up.

Answer 2

Explanation:

An object which moves in the positive direction has a positive velocity. If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a negative acceleration).
