I'm having trouble understanding some of the stuff regarding movement in my introductory physics class (I never thought I'd say that...)
Acceleration is defined as a=st2.
Distance can be calculated as the area under velocity-time line; given a constant accelation, and an initial velocity of 0, this forms a triangle: s=at22.
The latter, though, gives me the definition a=2st2. Is the former, then, wrong?
Perhaps I'm just better of using integrals?
EDIT (from comment below):
What confuses me is that a=ΔvΔt, and Δv when a is constant and V0 is 0 is v=ΔsΔt. Substituting v in the former equation: a=ΔsΔtΔt, or a=ΔsΔt2. Along with, of course, the SI unit sm2.
