Initial values are denoted with a subscript 0. Treat the motion as two independent one-dimensional motions, one horizontal and the other vertical. The kinematic equations for horizontal and vertical motion take the following forms. Horizontal Motion(ax = 0) x = x0 +vxt vx = v0x = vx = velocity is a constant.

Projectile Motion. Resolve the motion into horizontal and vertical components along the x- and y-axes. The magnitudes of the components of displacement s → s → along these axes are x and y.
The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its vertical motion.
In projectile motion, there is no acceleration in the horizontal direction. The acceleration, \(\mathrm{a}\), in the vertical direction is just due to gravity, also known as free fall: \[\begin{align} \mathrm{a_x} & \mathrm{=0} \\ \mathrm{a_y} &\mathrm{=−g} \end{align}\]
11 sie 2021 · The vector →s has components →x and →y along the horizontal and vertical axes. Its magnitude is s and it makes an angle ϕ with the horizontal. To describe projectile motion completely, we must include velocity and acceleration, as well as displacement. We must find their components along the x- and y-axes.
The key to analyzing two-dimensional projectile motion is to break it into two motions, one along the horizontal axis and the other along the vertical. (This choice of axes is the most sensible, because acceleration due to gravity is vertical—thus, there will be no acceleration along the horizontal axis when air resistance is negligible.)
Along the x-axis: uniform velocity, responsible for the horizontal (forward) motion of the particle. Along the y-axis: uniform acceleration, responsible for the vertical (downwards) motion of the particle. Acceleration in the horizontal projectile motion and vertical projectile motion of a particle: When a particle is projected in the air with ...
