Lec 1 | 8.01 Physics I: Classical Mechanics, Fall 1999

No. Mass is the amount of matter in an object, measured in kilograms. This is invariant, wherever you are. Weight is the force that gravity exerts on an object, which is proportional to mass but varies depending on whether you're on earth or on Jupiter, and it is measured in Newtons. MKS units, substitute what you wish, but Weight and Mass are very different quantities.

Yeah I know. Earlier I posted a comment admitting I was wrong, but it apparently disappeared. The Youtube comment system isn't always working properly I guess.

I got a C in Thermodynamics because I spent most of the semester arguing with the prof that a pound was a measure of force, not mass (but engineers still like to say pound-mass, and pound-force..just so their equations can be more complicated)

Haha, yeah. Engineers are weird like that. Centrifugal force, deceleration, etc. The terminology gets convoluted.

were is a good school in CA that is good to go if you like physics and computers.

U Cal San Diego is famous for computing. Also, Cal Tech is world famous for almost everything technical. Feynman, Gel Mann taught there. If you google "mechanical universe" you can find a link to a caltech phy prof doing his physics lectures.

depends on when you go to the toilet... if you go to the toilet in the morning and then start to eat till the evening, you definetly will be heavier in the evening, but if you wheigh yourself in the morning, then start to eat and go to the toilet at night, think about that...
input should be proportional to output xD

eh dont really know what im talking about but isnt the equation Weight=mass*gravity?

His use of 'sec' rather that simply 's' is interesting. It's certainly not the convention in the UK - my physics teacher always used to say "there's no 'secs' in physics" which i thought was witty.

mass , could be measured in anything u want aND weight is the amount of that mass.
