Pound Foot per Square Second [lbf·ft/s²]
This unit represents a torque or moment of force per unit time squared (though it’s an uncommon combination and can sometimes be context-specific).
It combines pound-force (lbf), a unit of force, with foot (ft), a unit of length, divided by second squared (s²), a unit of time squared.
It may be used in dynamics or rotational mechanics when dealing with angular accelerations or rate changes of torque.
In basic terms:
1 lbf\cdotpft/s2=force×distance÷time2
1 lbf\cdotpft/s2≈1.35582 N\cdotpm/s2
Piconewton [pN]
Piconewton is a very tiny unit of force in the International System of Units (SI).
1 piconewton (pN) equals 10−12 newtons (0.000000000001 newton).
It is commonly used in molecular biology, biophysics, and nanotechnology to measure forces at the molecular or atomic scale.
To put it in perspective:
1 pN=0.000000000001 N
Piconewtons allow scientists to quantify incredibly small forces, such as those involved in DNA stretching or molecular interactions.
