[First Maximize this Window. [Wait until the applet loads completely {you will see a message down in the status bar at the bottom of this window saying "Applet DataGraph3 started" before pressing [play] button.]
Note on Buttons: When buttons are discussed in the text below they will be shown with the word enclosed by brackets all bolded. So the "play button" will be indicated by [play] .
A rectagular mass is attached to a spring and slides along a horizontal surface that exerts a frictional force ont it. The coefficients of kinetic and static friction between the surface and mass are m K and m S shown in the input boxes below.
The Clock Time is shown in the upper left corner of the graph. Time = 0 coincides with pushing of the [play]
If you press the [pause] to temporarily stop the motion, you can then [step>>] or [<<step] through the motion one frame at a time. This allows you to easily determine the position of the ball at any time. Press the [reset] to set the time back to the beginning (Time=0).
Initial Conditions
Drag the block first and then the [Play]. This will give you
the block without any initial velocity. You can get control of the input
boxes by pressing the [Update Values] twice to get rid of the drag
feature.
You can then [play] the conditions that have already been entered or you can enter your own values into the input boxes below. After you press the [Update Values] your values will be added to the animation. Then [play].
The positive direction for the position x of the sliding block and x-component of Velocity Vx are to the right. . Negative values will point to the left.
IMPORTANT:Scroll down so that all of the graph and the buttons below it are visible. Then press [play].
