How do positive and negative acceleration differ? Positive acceleration represents an object speeding up; negative acceleration represents an object slowing down.
Positive acceleration moves north or east; negative acceleration moves south or west.
Positive acceleration occurs when there is more velocity than speed; negative acceleration occurs when there is less velocity than speed.
Positive acceleration occurs when an object changes its speed but not its direction; negative acceleration occurs when an object changes both its speed and direction.

acceleration

Explanation:

acceleration determines whether you will be adding to or subtracting from the velocity. while negative acceleration means you will subtract from the current value of the velocity and a positive acceleration means you will add

✔ Positive acceleration represents an object speeding up; negative acceleration represents an object slowing down.

NOTE: Negative acceleration is also called as Retar-dation.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is
