You add them. For example, if a block is accelerating to the right at 2 m/s2 but is being slowed by friction accelerating the block to the left at 1 m/s2, then you can add the accelerations--positive is right and negative is left. The net acceleration would be 1 m/s2
to the right.
Positive acceleration occurs when an object's velocity is increasing over time, while negative acceleration (or deceleration) happens when an object's velocity is decreasing over time. Positive acceleration can be due to speeding up, turning, or changing direction, while negative acceleration is typically caused by slowing down or stopping.
If you have a negative acceleration, you are slowing down. Acceleration is the rate of change of speed, so a negative acceleration means a decrease in speed.
When velocity is negative and acceleration is positive, the object is moving in the negative direction and its speed is increasing. This means that the object is slowing down as it moves in the negative direction - essentially decelerating.
If an object travels with constant acceleration, its speed will change at a constant rate over time. The object's speed will increase if the acceleration is positive, decrease if it is negative, and remain constant if the acceleration is zero.
Like charges (positive-positive or negative-negative) repel each other, causing them to move apart. Unlike charges (positive-negative) attract each other, causing them to move closer together. This is due to the interaction of electric fields created by the charges.
Positive acceleration occurs when an object's velocity is increasing over time, while negative acceleration (or deceleration) happens when an object's velocity is decreasing over time. Positive acceleration can be due to speeding up, turning, or changing direction, while negative acceleration is typically caused by slowing down or stopping.
Its slowing down (but still moving).
if you are using magnets, they stick together.
If the positive direction was defined at the outset as the direction opposite to the direction in which the object happens to be moving just now, and the object is slowing down, then the acceleration is positive because, algebraically, the object's speed is increasing in the positive direction.
When negative and positive are mixed together, it is called a neutralization reaction. In this reaction, the positive ions from one substance combine with the negative ions from the other substance to form a product that is electrically neutral.
What happens when you inadvertently crossed the positive battery terminal from a negative to a positive and a positive to a negative.?Read more: What_happens_when_you_inadvertanly_crossed_the_positive_battery_terminal_from_a_negative_to_a_positive_and_a_positive_to_a_negative.

Acceleration is negative.
If an object travels with constant acceleration, its speed will change at a constant rate over time. The object's speed will increase if the acceleration is positive, decrease if it is negative, and remain constant if the acceleration is zero.
a negative divided by a negative is a positive
Becomes a negative.
