This is constant velocity motion. There is no horizontal acceleration (
This is constant acceleration motion. The projectile is in free fall, meaning it is only affected by gravity ( −gnegative g Independence: The physics-projectile-angle-problems
Before using any kinematic equations, resolve the initial velocity into its components using the launch angle Vertical component ( v0yv sub 0 y end-sub ): 2. Understand Key Principles This is constant velocity motion
