Does negative acceleration mean slowing down

Acceleration is used in math and physics to describe how the velocity of an object changes. However, it can be a little tricky to navigate the signs (positive and negative) of acceleration as it relates to velocity.

So, can acceleration be negative?

When is acceleration positive

Acceleration can be negative when velocity is decreasing. Negative acceleration and positive velocity means decreasing speed (speed is moving towards zero). Negative acceleration and negative velocity means increasing speed.

Deceleration occurs when acceleration and velocity have opposite signs.

Of course, negative acceleration is not theoretical, since it occurs in gravity and other natural phenomena.

In this article, we’ll talk about negative acceleration and when it can happen.

We’ll also look at some examples to make the concept clear.

Let’s get started.

Can Acceleration Be Negative?

Acceleration can be negative, and this happens whenever velocity is decreasing. This is because acceleration is the derivative of velocity.

That is, acceleration tells us how velocity is changing.

Negative acceleration means velocity is d
