Weight, in English usage, is ambiguous. In common usage it's used to describe the "mass" of an object. However, in the scientific community, weight is something much different. For example, a kilogram is a unit of mass, and the weight of a 1kg object is simply the product of the mass and Earth's gravitational acceleration: w = m*g. In English units, this is a bit more complicated, as you have to convert from pound-mass (lbm) to pound-force (lbf) or throw the unit of slugs (1 slug = 1 (lbf*s^2)/ft) into the equation.
Education is learning. Enlightenment is a realization of a new perspective on a situation or of a new approach to a problem. One can lead to the other.
To anyone who takes the time to read this entire article, I encourage you to look up any and every term you do not fully understand.

u can quote me definitions all u want but u lack fundamental understanding
a non-skidding rotating tire (zero slip angle and not "burning out or locking the brakes") is only under STATIC friction NOT dynamic friction
mechanical "weight" is MASS!!!!!! stop spreading dumbness around
engineers would use the term MASS
u r merely in training and r not a professional engineer
do u get 100% or more (bonuses points) on all your assignments and exams?
thought so
(perfect gpa DOES NOT COUNT as 100%)
understanding is NOT the same as reprinting facts (that merely means that u r as smart as a photocopier or fax machine)
reprinting formulae from a grade 10 science text book does not make u look smart (why did u bother?)
study hard.......
no offense
