WebMay 23, 2024 · When velocity changes with time it causes acceleration, and if the speed or velocity of the object is increasing then we say acceleration is positive. On other hand, if the speed or velocity... 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.

WebYes, it is possible to have negative velocity when acceleration is positive. Consider a body or an object moving in a negative direction, having a negative velocity and acceleration. If the object slows down, its acceleration vector will be in the opposite direction from its motion, i.e., positive.
