One of the basic animation techniques is moving an object from one location to another. This is accomplished in Flash by applying a Motion Tween between the start and the end frames.
Step 1
Open a new file. You'll notice that this movie has only one layer called Layer 1. It is always a good practice to put descriptive names of your choosing for the layers in a Flash file. To rename Layer 1, double click on its name and then type the new name, something like "Motion Tween".
Step 2
Our stage is set and it is now time to create an object.
Hightlight the first frame in the Time line and using the Oval Tool 
and draw a circle somewhere on the stage.
Step 3
To animated this circle so that it moves from one place to another, we have to convert it into a Symbol.
Click on the Arrow tool 
and select the circle you have just drawn. (The previous tutorial explains how to select objects using the Arrow tool). Flash places a sort of 'net' over selected objects. The image below shows what a selected and an unselected circle looks like.
Now click on Insert - Convert to Symbol. The Symbol Properties window pops up. In the name text field type "Ball" which is the name for our symbol and also make sure that the Behavior is set to Graphic (that is the default value). Click OK to convert the circle into a symbol.
Step 4
If the Symbol Library is not open, click Window - Library to display the library in which you will find your newly created symbol, "Ball". Click on its name to view the a thumbnail of the object.
Step 5
Place the circle (which is now a symbol) somewhere near the top-left corner of the stage.
Now right-click frame number 36 in the time line and select Insert Keyframe
This adds a key frame at frame 36. With this frame selected, move the circle symbol and place it near the top-right corner of the stage. Thus, the circle is placed at its staring point (top-left) in frame 1 and at its ending point (top-right) in frame 36. We are all set to apply the animation.
Step 6
The last step is creating a Motion Tween between frame 1 and frame 36.
Right-click at any frame between 1 and 36, and from the drop down menu select Create Motion Tween
With the motion tween applied between frames 1 and 36, the layer should look something like:
To see how it works, click on Control - Rewind and then Control - Play.
