Questions tagged [projectile-motion]

This tag is for questions regarding to "projectile motion", the motion of an object thrown or projected into the air, subject to only the acceleration of gravity.

When a particle is thrown obliquely near the earth’s surface, it moves along a curved path under constant acceleration that is directed towards the center of the earth (we assume that the particle remains close to the surface of the earth).The object is called a projectile, its path is called its trajectory and the motion is called projectile motion.

Example: The motion of falling objects, as covered in Problem-Solving Basics for One-Dimensional Kinematics, is a simple one-dimensional type of projectile motion in which there is no horizontal movement.

  • In a projectile motion, the only acceleration acting is in the vertical direction which is acceleration due to gravity $(g)$.
  • Air resistance to the motion of the body is to be assumed absent in projectile motion.
  • Projectile motion only occurs when there is one force applied at the beginning on the trajectory, after which the only interference is from gravity.
  • Equations of motion can be applied separately in $X$-axis and $Y$-axis to find the unknown parameters.

For more details follow the references.

Projectile motion, solving for x and y when reflected by a given point at a given angle

x and y can be plotted for the 2D trajectory of a projectile by the following two primary equations. $x = v t \cos \theta$ $y = vt \sin \theta - \frac{1}{2} g t^2$ $where:$ $v = initial \, velocity$ $t = time$ $\theta = launch \, angle$ $g =…

Projectile motion model

In my studies regarding projectile motion, I recently completed a simple level question surrounding a multileveled golf range. I had to determine the trajectories of these balls after they were shot into the air. I was wondering if some sort of…

Determine the velocity of the skater when they reach the point at the bottom of the halfpipe

A skateboarder with a mass of $75$ kg rolls down a parabolic halfpipe (with shape described by the function $y = 0.2 x^2$). When the skateboarder is at a point $h_1 = 3$m above the ground, their velocity $v_1 = 3.0$ m/s. Neglecting friction,…

Graph a thrown object given angle and force

What is the equation for the graph of a thrown object (if it is thrown from the origin, ignoring air resistance), given its angle of elevation and throwing force (both constants)?

Projectile Motion - Speed Variations has no impact

https://www.youtube.com/watch?v=0jGZnMf3rPo Explain why the bullet would always hit the monkey by solving the projectile problem. Despite the initial speed to be of 13m/s or 9m/s, the monkey gets hit.
