Press Start to begin the animation.
Two circular objects will move with pre-defined velocity (yellow arrow).Click left mouse button to suspend the animation. Now, you can
Click near the circular boundary and drag the mouse button to change
Click near the center of the circle and drag the mouse to change its location.
When the two objects collide, the animation will be suspend.
At the moment when they collide, the force between the two circle objects
is along the line which connect the center of the two objects.
Now we have 1-D collision problem:
two object move in the direction along the line connect between their center,
with velocitys along this directions. (Red vectors)
The vector perpendicular to the above components (green vectors) will
not changed after collision.
(If there is no friction force between the two objects)
