Question 1

What is a piconewton?

Accepted Answer

A piconewton (pN) equals 10⁻¹² newtons. Standard unit for measuring forces on single molecules and proteins.

Question 2

Where are piconewtons used?

Accepted Answer

Optical tweezers, molecular motors, protein folding studies, and DNA stretching experiments.

Question 3

What's the difference between force and pressure?

Accepted Answer

Force (newtons) is a push or pull. Pressure (pascals) is force per unit area. Same force over smaller area = higher pressure.

Question 4

Why do we need different force units?

Accepted Answer

Newtons are SI standard. Pounds-force connects to everyday weight. Dynes (CGS) are used in some scientific fields. Each suits different applications.
