They do not HAVE to be, but the convention is to have them written horizontally. That makes it a little more universal.
Horizontal : y = 0Vertical: x = 2.
Horizontal : y = 0Vertical: x = -2.
The kind of function without an X variable.Y = 4is a horizontal line.
A vertical line has the equation [ x = a number ]. A horizontal line has the equation [ y = a number ].
It is the gradient: the change in the vertical direction divided by the change in the horizontal direction.
For vertical lines, when you try to figure out the slope, you get zero in the denominator - in other words, a division by zero.
Linear equations with one variable will either be horizontal or vertical lines. y=2 is a horizontal line going through (0,2)
Using the projectile motion equations and given the initial velocity and angle, we can calculate the time the shell is in the air. Then, we can find the horizontal range by multiplying the time of flight by the horizontal component of the initial velocity. The horizontal range in this case is about 1056 meters.
To determine the launch velocity of a projectile, you can use the projectile motion equations. By measuring the initial height, horizontal distance traveled, and the angle of launch, you can calculate the launch velocity using trigonometry and kinematic equations.
The graph would be a horizontal line crossing the y axis at "2". This means that x can be any number.

Common projectile problems in physics include determining the initial velocity, angle of launch, maximum height, range, and time of flight of a projectile. These problems can be solved using equations of motion, such as the kinematic equations, and applying principles of projectile motion, such as the independence of horizontal and vertical motion. By breaking down the problem into horizontal and vertical components, one can analyze the motion of the projectile and calculate the desired quantities.
