Question 1

What is a femtonewton?

Accepted Answer

A femtonewton (fN) equals 10⁻¹⁵ newtons. Used for measuring forces on DNA, proteins, and molecular interactions.

Question 2

How many piconewtons in a femtonewton?

Accepted Answer

One piconewton equals 1000 femtonewtons. So 1 fN = 0.001 pN.

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.
