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
Attonewton [aN]
Attonewton is an extraordinarily small unit of force in the International System of Units (SI).
1 attonewton (aN) equals 10−18 newtons (0.000000000000000001 newton).
It is used in highly specialized fields such as quantum physics, nanotechnology, and advanced experimental research where forces are incredibly minute.
To put it in perspective:
1 aN=0.000000000000000001 N
Attonewtons allow scientists to quantify forces at the tiniest scales imaginable, beyond typical atomic interactions.
