Final answer:
When you push down on a block on a table, the block atoms and table atoms in contact with each other move past each other.
Step-by-step explanation:
When you push down on a block resting on a table, the block atoms and table atoms that are in contact with one another move past each other. This is because atoms in a solid, such as the block and table, are held in place by forces represented by springs. When a force is applied, the atoms can slide over one another, allowing the block to be pushed down.
