## What does a negative slope mean in a velocity-time graph?

acceleration

Negative velocity and positive slope,: object is slowing down. Velocity-Time Graphs. If the V-T line has a negative slope, the object is undergoing acceleration in the negative direction.

**Can a velocity-time graph have a negative slope when?**

If the acceleration is negative, then the velocity-time graph is a downward sloping line (i.e., the slope is negative). If the acceleration is great, then the line slopes up steeply (i.e., the slope is great). This principle can be extended to any motion conceivable.

### What does a negative slope graph represent?

A negative slope means that two variables are negatively related; that is, when x increases, y decreases, and when x decreases, y increases. Graphically, a negative slope means that as the line on the line graph moves from left to right, the line falls.

**What does the slope of a velocity-time graph indicate?**

The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant.

#### What does negative velocity mean?

An object which moves in the negative direction has a negative velocity. If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a positive acceleration).

**What does a positive and negative slope represent for a velocity vs time graph?**

The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is positive, then the slope is positive (i.e., an upward sloping line). If the acceleration is negative, then the slope is negative (i.e., a downward sloping line).

## What does a positive and negative slope represent for a velocity versus time graph?

**What is the meaning of positive and negative slope in velocity time graph?**

### What does positive or negative velocity mean?

As learned in Lesson 1, a positive velocity means the object is moving in the positive direction; and a negative velocity means the object is moving in the negative direction.

**What does negative velocity and negative acceleration mean?**

Negative velocity = You move backwards. Negative acceleration = You slow down or you go faster in the backwards direction.

#### What is negative velocity?

**Which graph shows a negative acceleration?**

The velocity-time graph shows a line with a negative (downward) slope (meaning that there is a negative acceleration); the line is located in the negative region of the graph (corresponding to a negative velocity).

## What does the slope of velocity time graph tell us?

The Meaning of Slope for a v-t Graph. As discussed in the previous part of Lesson 4, the shape of a velocity versus time graph reveals pertinent information about an object’s acceleration. For example, if the acceleration is zero, then the velocity-time graph is a horizontal line (i.e., the slope is zero).

**What does the slope of a V-T graph mean?**

The Meaning of Slope for a v-t Graph. If the acceleration is negative, then the velocity-time graph is a downward sloping line (i.e., the slope is negative). If the acceleration is great, then the line slopes up steeply (i.e., the slope is great). This principle can be extended to any motion conceivable.

### Is the slope of the line equal to the acceleration?

So in this case, the slope of the line is equal to the acceleration of the velocity-time graph. Now we will examine a few other graphs to see if this is a principle that is true of all velocity versus time graphs. Now consider a car moving with a changing velocity. A car with a changing velocity will have an acceleration.

**What does negative velocity mean on displacement graph?**

(Note the difference with the displacement graph!) The period from 15 min to 30 min for example, shows the object slowing down, but still moving forward. When this line crosses the t-axis, the object has (momentarily) stopped, and is in the process of changing direction. Negative velocity must mean movement in the opposite direction.
