It can change the direction of motion or it can speed up or slow down an object.
positive acceleration helps to increase the velocity for positive direction while negative acceleration resists the motion.
Acceleration is positive when an object is speeding up in the positive direction (e.g., increasing velocity), and negative when the object is slowing down in the positive direction or moving in the negative direction (e.g., decreasing velocity). The sign of acceleration depends on the direction of the change in velocity relative to the direction of motion.
The car is slowing down
Its slowing down (but still moving).
Snowboarding demonstrates speed, velocity, and acceleration. It can also demonstrate a positive or negative value for velocity and acceleration.
Force is equal to mass multiplied by acceleration. Acceleration is change in velocity either positive or negative. Mass is always positive.
A positive acceleration is a change in velocity such that the latter velocity is greater than the former velocity and is therefore going fasterwhile a negative acceleration or deceleration is a change in velocity such that the latter velocity is lesser than the former velocity and is therefore going slower.Now let us look at the equation of a uniform acceleration (the change in velocity is uniform):a = (vf-vi)/sIf the final velocity is greater, you will have a positive acceleration. If the initial velocity is greater, you will have a deceleration.

Oscillating acceleration refers to the repeated back-and-forth motion of an object's acceleration, where the magnitude and direction of acceleration change over time. This type of motion is common in systems like pendulums or springs where the acceleration alternates between positive and negative values.
A negative velocity in a moving object indicates that the object is moving in the opposite direction of its positive velocity. The consequences of a negative velocity can include a change in position, direction, and speed of the object. It can also affect the object's acceleration and overall motion.
well the difference between positive and negative velocity would have to be that if your motion speeds up than you have a positive and when or if your motion slows down then you would have a negative accelerarion!!!!
An object slowing down can have an acceleration that is not negative if it is moving in the opposite direction of its velocity. In this case, the acceleration would be in the same direction as the object's motion, even though it is slowing down. This can happen, for example, when an object is moving in the positive direction but experiencing a negative acceleration due to a force in the negative direction.
