physics - How do i make an object move in 2d motion?

Question

so, I use glowscript for school and I'm having trouble figuring out how to make the sphere move in 2D motion, where it should look like a line curving downward... Here's my code:

GlowScript 3.0 VPython
scene.range = 20
force1=vector(-1, 0, 0)
force2=vector(-3, 0, 0)
Fnet = force1+force2
mass = 6
acceleration = Fnet/mass
ball = sphere(pos=vector(-28,0,0),radius = 1, color = color.yellow)
ar = shapes.arc(radius=2, angle1=0, angle2=pi/2)
velocity = vec(1,0,0)
deltat = .01
while True:
    rate(157)
    velocity = velocity+acceleration*deltat
