How would a graph of negative and positive acceleration differ?
This depends on what the graph represents. If it is a graph of velocity on the vertical and time on the horizontal, then if acceleration is at a constant rate, the graph will be a straight line with positive slope (pointing 'up'). If acceleration stops, then the graph will be a horizontal line (zero acceleration or deceleration). If it is deceleration (negative acceleration), then the graph will have negative slope (pointing down).

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 y…ou would have a negative accelerarion!!!!
when velocity is increasing,accleration is positiveand when velocity is decreasing,accleration is said to be negative.
The line would decrease as the time increased and it would stop once it touched the X axis because you cannot have a negative velocity. This graph would represent an inverse r…elationship between velocity and negative acceleration/
Acceleration is defined as : When velocity of a body gradually increases with time we say that the body is accelerating with respect to time Retardation is defined as : … when the rate of velocity of a moving body decreases it is called retardation
Positive acceleration results in the object speeding up, such as a car going from 0mph to 30mph. Negative acceleration is the object decelerating, such as using the brake in a… car.
If a function Y is dependent on X. if X increases in value then Y also increases then we call this a positive relationship. If X increases in value then Y decreases or vice ve…rsa then we call this a negative relationship.
Acceleration is a vector. It has both a magnitude and a direction. So you first have to choose which direction is positive. Lets say we choose "left" as negative and "right" a…s positive.. If an object is increasing speed (positive magnitude) while moving Right (positive direction) its acceleration is Positive'. If an object is decreasing speed (negative magnitude) while moving Right (positive direction) its acceleration is Negative.. If an object is increasing speed (positive) while moving Left (negative direction) its acceleration is Negative.. If an object is decreasing speed (negative) while moving Left (negative) its acceleration is Positive.. For vertical motion you would probably choose "up" as positive and "down" as negative.
Positive acceleration means the magnitude of velocity is increasing , i.e. something is speeding up. Negative acceleration means the magnitude of velocity is decreasi…ng , i.e. something is slowing down.
Actually, it depends on how you define the coordinate axes, but usually when moving forward, negative acceleration decreases speed, positive acceleration increases it.
You arbitrarily define a direction to be positive and the direction opposite to it is then negative. Measurements in the first direction are positive and those in the second a…re negative. For example, if you are considering the motion of a ball that is thrown upwards, you could choose the upward direction to be positive. Then the initial velocity of the ball would be positive but the acceleration due to gravity (which is acting in the downward direction) would be negative acceleration. But you could, instead, choose to call the downward direction positive. In that case, the initial velocity of the ball would be negative and the acceleration due to gravity would be positive acceleration. So it is all relative. Another way to look at it is that if the object being studied is slowing down it is negative acceleration and if it is speeding up it is positive. [Unfortunately that does not work with the above example because the object is slowing down initially and then speeding up.]
If acceleration is negative the graph looks like a upside U and decreases in value as time continues If acceleration is constant the graph is a straight line (linear) at 0 or… whatever the velocity is
Yes, acceleration can be positive and negative because acceleration is a vector. It has both direction and magnitude. The direction is what makes it positive or negative. Nega…tive acceleration is usually called deceleration.

The negative sine graph and the positive sine graph have opposite signs: when one is negative, the other is positive - by exactly the same amount. The sine function is said to… be an odd function. The two graphs for cosine are the same. The cosine function is said to be even.
If the constant acceleration is positive, the graph would be an exponential (x 2 ) graph. If there is constant acceleration, then velocity is always increasing, making the pos…ition change at an ever increasing rate.

A speed graph measures the distance devided over time. Acceleration graph measures the change in speed over time.

Yes. Mathematically, they have opposite signs. So they are opposing vectors. In terms of physics, they represent the effects of forces acting in opposite directions.
If the x-axis is time and the y-axis is location, the graph will beconcave upwards because with positive acceleration, the secondderivative of the graph is positive. Another w…ay to put it is that for x-axis as time and the y-axis aslocation, as you move in the positive x direction, the rate atwhich y goes up will increase - with the slope becoming more andmore vertical.
