projectile
(noun)
Any object propelled through space by the application of a force.
Examples of projectile in the following topics:
-
Key Points: Range, Symmetry, Maximum Height
- Projectile motion is a form of motion where an object moves in parabolic path.
- The time of flight of a projectile motion is exactly what it sounds like.
- Once the projectile reaches its maximum height, it begins to accelerate downward.
- The range of the projectile is the displacement in the horizontal direction.
- Construct a model of projectile motion by including time of flight, maximum height, and range
-
Constant Acceleration
- Analyzing two-dimensional projectile motion is done by breaking it into two motions: along the horizontal and vertical axes.
- Projectile motion is the motion of an object thrown, or projected, into the air, subject only to the force of gravity.
- The object is called a projectile, and its path is called its trajectory.
- The motion of falling objects is a simple one-dimensional type of projectile motion in which there is no horizontal movement.
- Throwing a rock or kicking a ball generally produces a projectile pattern of motion that has both a vertical and a horizontal component.
-
Solving Problems
- Using that information, we can solve many problems involving projectile motion.
- Projectile motion is when an object moves in a bilaterally symmetrical, parabolic path.
- Now, let's look at two examples of problems involving projectile motion.
- The projectile is thrown at $25\sqrt{2}$ m/s at an angle of 45°.
- Introducing the "Toolbox" method of solving projectile motion problems!

Basic Equations and Parabolic Path
- Projectile motion is a form of motion where an object moves in a bilaterally symmetrical, parabolic path.
- In a previous atom we discussed what the various components of an object in projectile motion are.
- In this equation, $u$ stands for initial velocity magnitude and $\small{\theta}$ refers to projectile angle.
- As we discussed previously, $T$ depends on the initial velocity magnitude and the angle of the projectile:
- In projectile motion, there is no acceleration in the horizontal direction.
-
Zero Launch Angle
- Projectile motion is a form of motion where an object moves in a parabolic path.
- Projectile motion occurs when a force is applied at the beginning of the trajectory for the launch (after this the projectile is subject only to the gravity).
- One of the key components of the projectile motion, and the trajectory it follows, is the initial launch angle.
- The angle at which the object is launched dictates the range, height, and time of flight the object will experience while in projectile motion. shows different paths for the same object being launched at the same initial velocity and different launch angles.
- Projectile moving following a parabola.Initial launch angle is $\alpha$, and the velocity is $v_0$.
-
Motion with Constant Acceleration
- The motion of falling objects is a simple, one-dimensional type of projectile motion in which there is no horizontal movement.
- If you were to throw the rock instead of just dropping it, it would follow a more projectile-like pattern, similar to the one a kicked ball follows.
- Projectile motion is the motion of an object thrown or projected into the air and is subject only to the acceleration of gravity.
- The object thrown is called a projectile, and the object's path is called its trajectory.
- In two-dimensional projectile motion, there is both a vertical and a horizontal component.
-
General Launch Angle
- The initial launch angle (0-90 degrees) of an object in projectile motion dictates the range, height, and time of flight of that object.
- You have an object that is being launched into projectile motion.
- Projectile motion is a form of motion where an object moves in a bilaterally symmetrical, parabolic path.
- Projectile motion only occurs when there is one force applied at the beginning of the trajectory, after which the only interference is from gravity.
- One of the key components of projectile motion and the trajectory that it follows is the initial launch angle.

Pylorospasm and Pyloric Stenosis
- Pyloric stenosis (infantile hypertrophic pyloric stenosis) causes severe projectile non-bilious vomiting in the first few months of life.
- Pyloric stenosis (or infantile hypertrophic pyloric stenosis) is a condition that causes severe projectile non-bilious vomiting in the first few months of life.
- The vomiting is often described as non-bile stained (non bilious) and projectile vomiting, because it is more forceful than the usual spittiness (gastroesophageal reflux) seen at this age.
- Very occasionally the myotomy was incomplete and projectile vomiting continues, requiring repeat surgery.
-
Scientific Applications of Quadratic Functions
- The maximum height of a projectile launched directly upwards can also be calculated from a quadratic relationship.
- The same maximum height of a projectile launched directly upwards can be found using the time at the projectile's peak ($t_h$):
