Speed is scalar, velocity is vectorial in "easy" words speed is the quantity of distance units per time units
while velocity is speed plus a defined direction and sense

--------------------- MERGED ---------------------------

Example an object that is mooving at a speed of 7 kmh
can have an horizontal velocity of 5 km/h, a vertical velocity of 5km/h and a Z velocity of 0 km/h (By Z i mean the 3rd axis of a 3d space)
EDIT: I didn't made the calculation for units, so the units I gave migth be wrong scince i made it in my head and it is just an example xD

No, i'm not (in school) i just like math and science ^^
I was wondering if OP was doing them because that's where you use this stuff. After partial derivatives comes surfaces and then cylindrical and spherical coordinates and then vector fields and more crazy stuff. Oh man, I'm getting stressed out and I already passed that stuff...
