When comparing the magnitude of acceleration, the sign indicates the direction, but if there is - 2m|s and#178; and - 5m|s and#178;, it is the absolute value, right

Because acceleration is a physical quantity to describe the speed change in five days, whether it is positive or negative - 2m | S & # 178; it means that the speed change of an object every second is 2m / s, which means deceleration, while - 5m | S & # 178; it means that the speed change of an object every second is 5m / s, which means deceleration
