Final answer:
The pitch of a screw is the distance between the threads. It determines how fast the screw moves through a material when it is being turned.
Step-by-step explanation:
The pitch of a screw is the distance between the threads.
For example, if you measure the distance from one thread to the next on a screw, that would be the pitch. It is often measured in millimeters or inches. The pitch determines how fast the screw moves through a material when it is being turned.
Knowing the pitch of a screw is important because it helps determine the mechanical advantage and efficiency of using a screw as a simple machine.
