How does the downward component of the motion of a projectile compare to the motion of free fall?
When you answer the question, please also explain WHY, because I don’t just want the answer, I want to learn also =)

because with gravity...the speed of an object accelerates...at about 9X speed per second (on earth)...but it eventually finds a fixed speed because of wind friction...a projectile with just motion will continue at the same speed/inertia until another force acts upon it...then it might change direction or speed...the speed atwhich a projectile falls b/c of gravity = the same speed it falls in free fall under the same conditions

the downward component of the motion of a projectile is equal to the motion of free fall. because there is only P which is the force cause the motion of the project, if we neglect the friction of air

Most projectiles are fired upwards. They will attain some maximum height, at which point
(vo)y = g*t. (vo)y is the upward component of the fired projectile, t is the time to reach max height and g is gravitational accleration.
From this point, the downward component of the projectile will be the same as that of an object dropped from the same height.
