Lab 3: Two Dimensional Motion Introduction There are many factors that go into determining the equations for the path of a projectile, such as gravity, mass, initial velocity, and initial height to name a few. There are four basic equations that can be used to model the motion of a projectile in a two dimensional plane. The first equation, x = x 0 + v 0x t , states that the horizontal position x is equal to the sum of the initial height x 0 and the product of the initial velocity in the x- direction v 0x and the time elapsed t . The next equation, y = y 0 + v 0y t - 1/2gt 2 , says that the vertical position y is equal to the sum of the initial vertical position y o and the product of the initial vertical velocity v 0y and the time elapsed t minus the product of half the effect of gravity g and the square of the time elapsed t . The third equation, v y = v 0y - gt , states that the velocity in the y-direction v y is equal to the initial velocity in the y-direction v 0y minus the product of the effect of gravity g and the time elapsed t . The final equation, v x = v 0x , only states that the velocity in the x-direction will always be the same as its initial
