I agree with this opinion, velocity and acceleration is a vector quantity that has direction. so the value of the velocity and acceleration, can be positive and negative depending on …

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. WebPositive, Negative and Zero Acceleration. Consider the velocity-time graph shown above. Here, between the time intervals of 0-2 seconds, the velocity of the particle is increasing with respect to time; hence the body is experiencing a positive acceleration as the slope of the v-t curve in this time interval is positive.

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.
