Is g always negative in projectile motion
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. Webprojectile motion. It is derived using the kinematics equations: a x = 0 v x = v 0x x = v 0xt a y = g v y = v 0y gt y = v 0yt 1 2 gt2 where v 0x = v 0 cos v 0y = v 0 sin Suppose a projectile is thrown from the ground level, then the range is the distance between the launch point and the landing point, where the projectile hits the ground.
