Hi, I was always told that positive acceleration means that an object is always speeding up. However, I am starting to question this. I know that if an object is speeding up in the positive direction, the acceleration is positive. However, if an object is slowing down in the negative direction, the calculated acceleration will be positive, even though the object is slowing down. If an object is slowing down in the negative direction, is this considered positive acceleration.? For example, in the graph below (please ignore the area calculations), the object experiences positive acceleration during 0-2s and 10-12s. Is the object also experiencing positive acceleration during 8-10s? Thanks! All help is very much appreciated!
