Question

What do you understand about negative acceleration?

Answer 1

The answer to the question is that acceleration is of two types, positive and negative.

Firstly Acceleration can be defined as the alterations in the velocity per unit of a given time.

Negative acceleration is further divided into two types.

First, when the object is in motion and then it starts to slow down its speed.

Here the acceleration is said to be in the negative value.

The second type is when the direction of the acceleration, as well as the direction of the velocity, are the same and at that moment the object raises its speed.

Answer 2

Answer:

That means that the direction of the acceleration determines whether you will be adding to or subtracting from the velocity. Mathematically, a negative acceleration means you will subtract from the current value of the velocity, and a positive acceleration means you will add to the current value of the velocity.
