"FORCE IS PRODUCT OF MASS MULTIPLIED BY SPEED."
Okay, hold on, hold on there, right there.
I do not know whether it is a translation error or error in the original language.
2 things wrong with that sentence.
First, FORCE is PRODUCT of MASS and ***ACCELERATION***
F = ma
Second, PRODUCT of two measurements already means the multiplication of the two measurements.
So grammatically, the inclusion of the term "multiplied" in the sentence is incorrect.
Okay, now back to the story.
