The term negative acceleration is used when something is slowing down from its motion. When pushing the brakes the car will negatively acceleration to slow down .

What is the term that describes a decrease in acceleration?
it is still acceleration, but it is negative.
Can acceleration be a negative number?
Yes, the scalar value of acceleration can be a negative number. Acceleration is the rate of change of velocity. If the speed of an object is reducing (it is slowing down), then the object is subject to a negative acceleration. An example is when you apply the brakes in a car. The brakes change the speed of the car from a higher value to a lower value, thus imposing a negative acceleration. Colloquially, people speak of deceleration, however the correct term is negative acceleration.
When can you used the positive acceleration due to gravity and negative acceleration due to gravity?
If you define the "up" direction as "positive", then the acceleration is negative, because it is downward. If you define "down" as positive, then acceleration is negative. You can use any convention; just be sure to be consistent within a particular calculation, to avoid errors.
What is positive and negative acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
What would a negative acceleration tell you about the object in motion?
the car is at a constant speed---------------------------------------------------------I'm pretty sure that if the acceleration is negative, the car is slowing down. But if the velocity is negative, the car is either heading south or down (velocity refers to speed and direction.. according to my physics teacher).
What is the term that describes a decrease in acceleration?
it is still acceleration, but it is negative.
What is the term for negative acceleration?
deceleration aka slowing down?
Is the negative acceleration the same as deceleration?
Yes no doubt. It is a short term.
Can acceleration be a negative number?
Yes, the scalar value of acceleration can be a negative number. Acceleration is the rate of change of velocity. If the speed of an object is reducing (it is slowing down), then the object is subject to a negative acceleration. An example is when you apply the brakes in a car. The brakes change the speed of the car from a higher value to a lower value, thus imposing a negative acceleration.

Can a car have negative velocity and negative acceleration?
It cannot have negative velocity, it can have negative acceleration.
Why do scientist often refer to deceleration as negative acceleration?
Deceleration is often referred to negative acceleration because deceleration is not AA commonly used word.
Can there be a positive acceleration and a negative acceleration?
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.
What is negative and acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
When can you used the positive acceleration due to gravity and negative acceleration due to gravity?
If you define the "up" direction as "positive", then the acceleration is negative, because it is downward. If you define "down" as positive, then acceleration is negative. You can use any convention; just be sure to be consistent within a particular calculation, to avoid errors.
Is it true that a negative acceleration always means that a moving object is decelerating?
Yes. That is what the term deceleration means.
What is positive and negative acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
True or false Negative acceleration always means that a system is slowing down?
false A car can have a negative acceleration and be speeding up. A negative acceleration determines the direction of the acceleration A car with forward acceleration will speed up in the forward direction A car moving forward with a negative acceleration will slow down A car not moving with a negative acceleration will speed up in the backward direction A car moving backward with a negative acceleration will speed up in the backward direction
