Now consider a paper clip on a table.

A hand holds a magnet just above the clip.

The clip jumps up toward the magnet.

The magnet pulls the clip. The magnet does not touch the clip.

The magnet's pull is a force that doesn't touch.

Does the magnet touch the clip? No. The magnet's pull is a force that doesn't touch.

Now the magnet moves away.

The clip falls back to the table. Earth pulls it down.

Earth does not touch the clip.

Earth's pull is a force that doesn't touch.

The magnet has moved away. Does Earth touch the clip? No. Earth's pull is a force that doesn't touch.

But now a finger pushes the clip along the table.

The finger touches the clip.

The finger's push is a force that touches.

Does the finger touch the clip? Yes. The finger's push is a force that touches.
