Frequently Asked Questions
-
What is a femtonewton used to measure?
-
A femtonewton measures extremely small forces, such as those at the molecular and nanoscale levels in force spectroscopy and optical trapping experiments.
-
Where are teranewtons typically applied?
-
Teranewtons quantify extremely large forces, including planetary gravitational forces, impact simulations, and massive engineered structures.
-
Why use scientific notation with this conversion?
-
Because the conversion spans forces differing by many orders of magnitude, scientific notation helps express extremely large or small numbers clearly.
Key Terminology
-
Femtonewton [fN]
-
A unit of force equal to 10^-15 newtons, used to quantify very small forces at molecular and nanoscale levels.
-
Teranewton [TN]
-
An SI derived unit of force equal to 10^12 newtons, used for expressing extremely large forces such as planetary scales.
