Acceleration. 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: \[\begin{align} \mathrm{a_x} & \mathrm{=0} \\ \mathrm{a_y} &\mathrm{=−g} \end{align}\]
(C) analyze and describe accelerated motion in two dimensions using equations, including projectile and circular examples.
In a Projectile Motion, there are two simultaneous independent rectilinear motions: 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.
With these conditions on acceleration and velocity, we can write the kinematic Equation 4.11 through Equation 4.18 for motion in a uniform gravitational field, including the rest of the kinematic equations for a constant acceleration from Motion with Constant Acceleration.
The overall motion, then, is a combination of motion with constant velocity horizontally, and motion with constant acceleration vertically, and we can write down the corresponding equations of motion immediately: \begin{align} v_{x} &=v_{x, i} \nonumber \\ v_{y} &=v_{y, i}-g t \nonumber \\ x &=x_{i}+v_{x, i} t \nonumber \\
Projectile motion is a form of motion experienced by an object or particle (a projectile) that is projected in a gravitational field, such as from Earth's surface, and moves along a curved path under the action of gravity only.
