Can Acceleration be negative?

Yes, acceleration can be negative. In physics, acceleration is a vector quantity that measures the rate at which an object changes its velocity. It can be positive, negative, or zero, depending on the direction and magnitude of the change in velocity.

When an object is slowing down, its velocity is decreasing in magnitude, which means the change in velocity is negative. In this case, the acceleration is also negative. Similarly, if an object is moving in the opposite direction of a positive reference point, its velocity is negative, and therefore the acceleration will also be negative.

To determine if the acceleration is positive or negative, you need to analyze the change in velocity and the direction of motion of the object. If the velocity and motion are in the same direction, the acceleration is positive. If the velocity and motion are in opposite directions, the acceleration is negative.
