## What is the equation for a position vs time graph?

Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).

What does it mean when the position vs time graph is a parabola?

The position vs. time graph of an object with constant acceleration is a parabolic curve. The curvature is upward for positive acceleration and downward for negative accelerations. The intercept is the initial position, in this example 2 m.

What is slope of a graph?

Identify slope from a graph. Using two of the points on the line, you can find the slope of the line by finding the rise and the run. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: Slope =riserun Slope = rise run .

### What does the slope of a position-time graph gives?

The slope of the position-time graph gives the speed of the object.

What does the slope of position-time graph gives?

Why is a position graph curved?

If a position graph is curved, the slope will be changing, which also means the velocity is changing. Changing velocity implies acceleration. So, curvature in a graph means the object is accelerating, changing velocity/slope.

#### What is the formula for slope of a graph?

The slope equals the rise divided by the run: Slope =riserun Slope = rise run . You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it.

What is the slope of velocity time graph gives?

acceleration
The slope of the velocity-graph is called acceleration. Because an object goes from one point to another and the change in velocity does not remain constant.

Is a speed-time graph?

Speed-time graphs In a speed-time graph speed is always plotted on the vertical axis and time is always plotted on the horizontal. This represents the motion of a particle accelerating from a speed at time 0 , u , to a speed v at time t .

## Can a position time graph have a negative slope?

Yes. The slope of position time graph gives velocity. And velocity can be negative.

How to read a position vs time graph?

How to read a position vs. time graph. Using the graph to determine displacement, distance, average velocity, average speed, instantaneous velocity, and instantaneous speed. Created by David SantoPietro.

Which is an example of a parabolic graph?

The position vs. time graph of an object with constant acceleration is a parabolic curve. The curvature is upward for positive acceleration and downward for negative accelerations. The intercept is the initial position, in this example 2 m. for the situation of because they are relatively unexciting.

### What does point of zero slope in position vs time graph mean?

A point of zero slope in a position vs. time graph implies that the velocity goes to zero at that time. Thus, the system is momentarily at rest at the time corresponding to the vertex of the parabola. Everywhere to the right of the vertex in the graph, the slope of the parabola is positive and increasing.

Is the slope of the parabola positive or negative?

Everywhere to the right of the vertex in the graph, the slope of the parabola is positive and increasing. Thus, the velocity is increasing in the positive direction, implying positive acceleration. Everywhere to the left of the vertex, the velocity is negative and approaching zero (becoming smaller in magnitude).
