# What is the difference between negative and positive acceleration?

###### Wiki User

Positive acceleration means the magnitude of velocity is increasing,

i.e. something is speeding up.

Negative acceleration means the magnitude of velocity is decreasing,

i.e. something is slowing down.

Positive acceleration ==&gt; speeding up Negative acceleration ==&gt; slowing 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 you would have a negative accelerarion!!!!

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.

when velocity is increasing,accleration is positiveand when velocity is decreasing,accleration is said to be negative.

The difference between positive and negative momentum is the direction that the object is going. Left and down are negative, right and up are positive. For example: if a ball is rolling to the left, it has a negative momentum.

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 are 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.]

positive ions carry positive charge and negative ions carry negative charge

Positive looks like this + Negative looks like this -

Positive correlation has a positive slope and negative correlation has a negative slope.

The difference might be that one, the negative electron, is matter, and the other, the positive electron, is antimatter.

negative punishment is the removal of a positive stimulus following a behavior

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

The difference between a positive shear and a negative shear is the direction the image is distorted into

Its the Rh factor that determines if you are positive or negative.

When an object is moving with different velocity with respect to time then the object is in acceleration or decceleration mode. If the rate of change of velocity is positive then it is said to be accelerated, if its negative it is said to be deaccelerated.

to find the difference between a negative number and a positive number, you do the same thing as you would do for a positive and positive number. You just subtract the smaller number (which would of course be the negative) from the larger number (the positive). example: difference between 7 and -4 7 - (-4) = 11

The difference between a positive integer and a negative integer is ALWAYS positive.Suppose X and Y are positive so that -Y is negative,The the difference two numbers, A and B is A - B so the difference between X and (-Y) is X - (-Y) which equals X + Y. The sum of two positive numbers is always positive.

The difference between two numbers is the result of a subtraction. This can be either positive or negative.

Positive electric fields attract negative charges while negative electric fields attract positive charges.
