i think that its something about science
Acceleration and deceleration are both the rate at which velocity changes, Deceleration is a negative acceleration. In an equation the rate of deceleration is shown as a negative acceleration valueCentripetal acceleration is different and represents the rate of change of tangential velocity. There is no equivalent centripetal deceleration.
It would be in the negative direction as well. Newton's Second law states that the acceleration of an object directly depends on the net force given to that object.
Acceleration tells how velocity changes. If the acceleration is positive, the velocity is increasing; if it is negative, the velocity is decreasing. The equation that relates them is v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time.
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.
A positive acceleration is a change in velocity such that the latter velocity is greater than the former velocity and is therefore going fasterwhile a negative acceleration or deceleration is a change in velocity such that the latter velocity is lesser than the former velocity and is therefore going slower.Now let us look at the equation of a uniform acceleration (the change in velocity is uniform):a = (vf-vi)/sIf the final velocity is greater, you will have a positive acceleration. If the initial velocity is greater, you will have a deceleration.
If the numerator is negative and the denominator is positive then the fraction will be negative. If the numerator is negative and the denominator is negative too then the fraction will be positive.
positive or negative change of velocity or change of direction of the speed vector
It cannot have negative velocity, it can have negative acceleration.

No!If numerator and denominator have the same signs the fraction is positive.If numerator and denominator have opposite signs the fraction is negative.
The simplification will be positive. In other words, the numerator and the denominator will NOT stay negative.
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. Negative acceleration is usually called deceleration.
Positive acceleration = speeding up. Negative acceleration = slowing down.
Reduce it as you would normally, negative fractions are no different to positive fractions. Also, it doesn't matter which of the numerator or denominator are negative, as long as when it is reduced the fraction is negative overall.
-16m + 71 = 0Subtract 71 from both sides of the equation.-16m = -71Divide the whole equation by -16.m = 71/16The negative in the numerator and the negative in the denominator cancel each other leaving the final product positive.
