Constant acceleration equations

The 1-D equations are modified simply by adding an x or y subscript to all the vector variables. As in 1-D, the equations apply under the following conditions:

the acceleration is constant
the motion is measured from t = 0
plus and minus signs give directions for the vector components

The x-component equations

v_x = v_ox + a_x t

x - x_o = v_ox t + ½ a_x t²

x - x_o = ½ (v_ox + v_x) t

v_x ² = v_ox² + 2 a_x (x - x_o)

There is a similar set of equations for the y-direction. Simply replace all the x's by y's in the equations above.

IMPORTANT: When solving problems always keep the x-component data separate from the y-component data. The only thing that can be used in both sets of equations is time.
