Question

What is the difference between positive and negative acceleration

example.​

Answer 1

A positive acceleration means an increase in velocity with time.

Negative acceleration means the speed reduces with time. its a retardation.

If the speed is increasing, the car has positive acceleration.

When the car slows down, the speed decreases.

Answer 2

Answer:

That means that the direction of the acceleration determines whether you will be adding to or subtracting from the velocity. Mathematically, a negative acceleration means you will subtract

from the current value of the velocity,

and a positive acceleration means you

will add to the current value of the

velocity....
