Unformatted text preview: PROJECTILE MOTION, EVERYTHING YOU NEED TO KNOW Projectile motion is a special case of two- dimensional constant acceleration. It is special because the horizontal or x-component of acceleration can be approximated as zero. The vertical or y-component of acceleration is approximated as g . The initial x-position is defined as zero (x = 0). The direction or the trajectory angle θ is defined with respect to the horizontal. θ is positive if the object is rising, it is zero if it is moving horizontally, and it is negative if it is falling. For θ > 0, we define the positive y-axis as up: ↑ y and a y = g = -g If θ ≤ 0, then ↓ y and a y = g = + g. v x = v cos θ and v y = v sin θ where v is the initial speed and θ is the initial projection angle. (1) x = v x t Horizontal position as a function of time (2) y = y + v y t + 1/2 g t 2 Vertical position as a function of time (3) v y = v y + g t Vertical velocity as a function of time (4) v y 2 = v y 2 + 2 y g...
