Assumptions - Block on Springs

The applet simulates the forces acting on a vertically moving block. The block is supported by springs that in turn are resting on a platform (Table). The table can move upward or downward.

The motion of the block-springs-table system is shown in the steady when all parts of the system move with the same constant acceleration.

When the acceleration is changed from one value to another, the system again realizes its new steady state instantly. Any initial oscillations of the springs in response to a new table acceleration are not simulated.
