Learning About Motion
Webquest
Velocity and acceleration are different concepts, but are both related
to motion. In this webquest, you will learn about velocity and
acceleration through material on the Internet.
Write all your answers on the answer sheet.
Part
1: General Info
Use these websites to answer the following questions:

1. What is velocity?
2. What is acceleration?
3. Give an example of something accelerating.
Part 2: Roller coaster top
speeds
Some roller coasters go very fast. Go to a list of
the world's fastest roller coasters here.
4. What is the name of the world's fastest roller coaster?
How fast does it go?
5. How fast is the Superman roller coaster at Magic Mountain?
Roller coasters have large accelerations, almost as much as a jet
airplane! That is one reason they are fun. It is also why
they make some people sick.
6. Have you ever been on a roller coaster? Do you like
them? Why or why not?
Part 3: Car moving at
constant velocity.
Next, go to the physicslessons.com
moving car simulator, here.
This will show you a graph of the position,
velocity, and acceleration of a moving car. You can change the
initial
position, the initial velocity, and the acceleration of the car.
You
press the "Start" button to make the car move. The "x" graph is
the
position graph, the "v" graph is the velocity graph, and the "a" graph
is the acceleration graph.
Lets make the car move at a constant velocity. Set the initial
position to 0, the initial velocity to 3 m/s, and
the acceleration to 0. Click "Start" to see the graphs. Copy the
graphs into your paper.
Answer these questions based on what you saw:
7. Did the position of the car change? How?
8. Did the velocity of the car change? How?
9. Did the car speed up or slow down?
Part 4: Car moving at
constant acceleration.
Lets make the car accelerate. Set the initial position to 0, the
initial velocity to 0 m/s, and
the acceleration to 1 m/s2. Click "Start" to see the
graphs. Copy the
graphs into your paper in your paper.
Answer these questions based on what you saw:
10. Did the position of the car change? How?
11. Did the velocity of the car change? How?
12. Did the car speed up or slow down?
Part 5: Controlling
velocity and acceleration.
Go to the University of Colorado Maze Game. Click the
"Run Now" button to run the program. You control the red ball by
changing its speed, velocity, or acceleration.
First, move the ball by controlling its position. To control the
ball's
position, click the "R" button. Get the ball to the finish for
Level 1, Level 2, and the "Certain Death" level.
Next, move the ball by controlling its velocity.
To control the ball's velocity, click the "V" button. Get the
ball to the finish for Level 1, Level 2, and the "Certain Death" level.
Finally, move the ball by controlling its acceleration. To control the
ball's
position, click the "A" button. Get the ball to the finish for
Level 1, Level 2, and the "Certain Death" level.
When you are done, help feed starving people by answering questions at FreeRice,
or explore the NASA website.
