In a position-time graph, **the velocity of the moving object is represented by the slope, or steepness, of the graph line**. … The position of the object is not changing. The steeper the line is, the greater the slope of the line is and the faster the object’s position is changing.

## What do position vs time graphs tell you?

time graphs show how the velocity of a moving object changes over time. Because the slope of the position vs time graph tells **you the object’s velocity**, you can use it to create a velocity vs. time graph.

## How do you draw a position vs time graph?

Position time graph for a stationary object

[X]

As said earlier, a graph is drawn by **taking time along x-axis and position along the y-axis**. For a stationary object, its position will not change with time. That is, its position co-ordinate x_{t} is a constant and has the same value x_{} as at t = 0.

## What is position-time graph called?

Summary. Motion can be represented by a **position**-time graph, which plots position relative to the starting point on the y-axis and time on the x-axis. The slope of a position-time graph represents velocity. The steeper the slope is, the faster the motion is changing.

## How do you describe the motion of a graph?

If we set up our graph with position on the y-axis and time on the x-axis, a line on the graph that is rising **represents motion away** from the object’s initial position. … And a line that is moving downward represents that the object is moving backwards towards the initial position.

## What is the slope of a position vs time graph?

The principle is that the slope of the line on a position-time graph **is equal to the velocity of the object**. If the object is moving with a velocity of +4 m/s, then the slope of the line will be +4 m/s. If the object is moving with a velocity of -8 m/s, then the slope of the line will be -8 m/s.

## What does the slope of a distance-time graph represent?

In a distance-time graph, the slope or gradient of the line is **equal to the speed of the object**. The steeper the line (and the greater the gradient) the faster the object is moving. Calculate the speed of the object represented by the green line in the graph, from 0 to 3 s.

## What is the use of position-time graph?

A position-time graph shows **how far an object has traveled from its starting position at any given time since it started moving**.

## What is an acceleration vs time graph?

An acceleration vs. time graph plots **acceleration values on the y-axis, and time values on the x-axis**. … time graph, the slope at that point (derivative) will always be equal to the acceleration at that time. So, if at some moment your acceleration is positive, then at that moment your velocity will be increasing.

## What is a distance vs time graph?

If an object moves along a straight line, the **distance travelled** can be represented by a distance-time graph. In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.

## How do you describe a speed time graph?

A speed – time graph **shows us how the speed of a moving object changes with time**. The steeper the graph, the greater the acceleration. A horizontal line means the object is moving at a constant speed. A downward sloping line means the object is slowing down.

## How do you describe motion on a speed time graph?

**If an object moves along a straight line**, its motion can be represented by a velocity-time (or speed-time) graph. The gradient of the line is equal to the acceleration of the object.

## How do you describe the motion?

You can describe the motion of an object by **its position, speed, direction, and acceleration**. An object is moving if its position relative to a fixed point is changing. Even things that appear to be at rest move.

## What is the physical significance of the slope of your graph?

What is the physical meaning of the slope in a velocity time graph? 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 do you mean by slope of a graph?

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as “**rise over run**” (change in y divided by change in x).

## What does the slope of a distance-time graph gives Class 9?

The slope of the distance-time graph **indicates speed**. It is because the slope of a distance-time graph determines the speed of that body, so the steeper the slope greater will be the speed of the body.
