    I'm confused since I'm told that they aren't the same thing? But algebraically they are. Help?

    Do you mean negative acceleration?

    Definition of deceleration is that an object is slowing down, negative acceleration is reducing velocity (or becoming more negative) in a given direction. Deceleration isn't a vector but negative acceleration is.

    You can have a negative acceleration.
    All the negative means it is accelerating in the opposite way to whatever you have set as 'forwards' (Positive)

    Acceleration is when you move forward, so deceleration is when you don't.

    Guessing negative deceleration is when you **** up and crash your car or something.

    Yes, thank you. Damn physics is confusing.

    So a negative acceleration would be a mirror image of the accelerating graph about the x axis?

    What do the axis show?
