WebApr 11, 2024 · ax = 0 or ay = -g. The value of g is equal to 9.8 m/s. Horizontal velocity, ux, and Vertical velocity, uy. At any point in the projectile motion, the horizontal velocity remains constant. On the other hand, vertical velocity varies linearly. This is because acceleration is constant at 9.8 m/s. WebThe Shape of the Curve for the Projectile: Solving the x motion equation yields t = X V x the same as before and using this in the y motion equation yields Y = 1 2 g t2 = g V x 2 X2 in other words, 2 Y = g 2 V x 2 X which looks the same as plus y was down. However now g is negative g=-9.8 so the graph of the motion X versus Y appears-9.8 m ë s2
