Basic formulas I need to remember (that came up while studying for Desiree's class):

Work-energy theorem: $$\Delta x \: F = {\frac 1 2} m v^2$$ $$\Delta x \: F = {\frac 1 2} m \left({v_{final}^2 - v_0^2}\right)$$ $$\Delta x \: m a = {\frac 1 2} m \left({v_{final}^2 - v_0^2}\right)$$ $$\Delta x \: a = {\frac 1 2} \left({v_{final}^2 - v_0^2}\right)$$
