WebJul 1, 2024 · The sign of acceleration is the direction of the acceleration. If positive the acceleration is in the positive direction. If negative then the acceleration is in the negative direction. There are 4 cases: If the object is moving in the positive direction has a negative acceleration it is slowing down. WebThis sign is reasonable because the train initially has a positive velocity in this problem, and a negative acceleration would oppose the motion. Again, acceleration is in the same direction as the change in velocity, which is negative here. This acceleration can be called a deceleration because it has a direction opposite to the velocity.
