Question 1

What is an attonewton?

Accepted Answer

An attonewton (aN) equals 10⁻¹⁸ newtons—one quintillionth of a newton. Used in molecular and atomic force measurements.

Question 2

Where are attonewtons used?

Accepted Answer

Optical tweezers, molecular motors, DNA mechanics, and single-molecule force spectroscopy 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.
