Kinematic Equations in Two Dimensions | Physics with Professor Matt Anderson | M4-05

Let's go back to our fabulous kinematic equations, but now let's deal with them in two dimensions. Hmmm...sounds like fun.

Hi Prof Anderson at 9:26 there about, why didn't you use -9.8 m/s^2 for g, but you used positive g rather?

[@beutyindetail]

because we have multiplied by 1/2 and then divided by g, hence 2h/g. why it went from h - 1/2 gt^2 = 0, because we moved it to other side

Object when thrown up uses -ve g whereas an object falling down uses +ve g
