# Motion:Speed and Velocity

## How fast are you going ? Speed and Motion

### Purpose:

To be able to:

Created by: Dr. William Chavez

### Resources Needed:

You will need a computer connected to the internet as well as sheets found on this webquest. Many activities require plugins for your browser.

You will need Macromedia's - Flash and Shockwave plugins. (discontinued)

6. Can you guess which line is constant velocity, and which one is accelerating faster?

7. To see if you are correct, go to lesson on graphing velocity and acceleration.  Place the following different velocities at 0,5,10,and15.seconds in the tutorial and notice the lines that are similar to the graph above.

8. Draw the five graphs on graph paper and label whether the graph is showing constant velocity, acceleration, or deceleration.

9. For lab credit, do the lab on animating motion. Do activity 3, but you may have to look at the beginning of the lab to understand how to do activity 3.

Now that you have mastered the understanding of speed, maybe you would like to try your hand at some of these simulations.

## Teacher Notes

### Suggested Grade Level: 8-10 physical science

Science Content Standards:

1b Average speed is the total distance traveled divided by the total time elapsed. The speed of an object along the path traveled can vary.

1c How to solve problems involving distance, time, and average speed.

1d To describe the velocity of an object one must specify both direction and speed.

1e Changes in velocity can be changes in speed, direction, or both.

1f How to interpret graphs of position versus time and speed versus time for motion in a single direction.

9f Apply simple mathematical relationships to determine one quantity given the other two (including speed = distance/time, density = mass/volume, force = pressure x  area, volume=area x height).

1a How to solve problems involving constant speed and average speed.
