In standard Earth gravity, acceleration is steady and always negative.
Velocity is positive, goes to zero at apex (vertex), then goes negative.
y(t) = ½at² + v₀t + y₀ is the basic formula you need to know.
Standard gravity is -9.80665 m/s²

Vy tends to zero
Vx is equal to Vox (thus it remains constant all flight long
acceleration is constant and equal to g all flight long
