A projectile is an entity which only has the force of gravity acting upon it. A projectile can be cast, fired, flung, heaved, hurled, pitched, tossed and thrown. A projectile can be anything as long as it has initial horizontal velocity that is not equal to zero which has the acceleration due to gravity. Projectile motion happens when an object projected with a force stops putting influence on the object after its launched, hence the only force being gravity. The trajectory is the path of the projectile. There are three types of projectile motion as the following.

Projectiles 1: When an object is dropped from rest at an elevation or fired from elevation with an angle of zero.

Projectiles 2: When the object is thrown at an angle from no elevation with a parabolic trajectory.

Projectiles 3: When the object is thrown upwards at an angle from a higher elevation

Each projectile had its own separate calculations and equations. Projectiles are a 2 dimensional because the motion of the projectile is all one. When calculating projectiles you must consider the acceleration due to gravity because that’s the single force acting upon it and assume that there is no air resistance.

When analyzing Projectile you usually are trying to find the initial velocity, initial horizontal velocity, initial vertical velocity, range which is how far the projectile has travelled, the final vertical and horizontal velocity, time of flight, height of flight, time taken to reach maximum height of the flight and total height. When looking at a projectile you are trying to find the properties if it in the y and x components. Projectiles 1 have a parabolic trajectory and the component of the x value for the component for the y value are the same. In Projectiles 2 again there is a parabolic trajectory and everything on the right-hand side of the path is equal to the left hand side. In projectiles 3, the calculations are similar once...

...Projectile Motion
Experiment # 4
Introduction:
Projectile Motion exists commonly in our everyday lives and is particularly evident in the motion or flight of objects which are projected from a particular height. The key to working with projectile motion is recognizing that when an object with mass is flying through the air, its motion is a combination of vertical and horizontal movements. Although the horizontal velocity of the object remains constant throughout the flight, it’s vertical velocity accelerates or decelerates due to gravity.
Purpose:
The purpose of this experiment is to be able to measure the velocity of a ball using two Photogates and computer software for timing, apply concepts from two-dimensional kinematics to predict the impact point of a ball in projectile motion and ability to understand trial-to-trial variations in the velocity measurement when calculating the impact point.

...Yr. 12 Physics Assessment Task #1: Part A
Open ended investigation By Rex Whiticker
Projectile Motion
Abstract:
The Project motion of a catapult being fired is varied by a range of factors that affect the path of the projectile. In this experiment, the angle of trajectory, mass of the projectile and change in initial velocity of the launch, were all factors considered in the end result to investigate the properties of projectile motion. The purpose of the experiment was to conduct a first-hand investigation to design and analysis how angle, weight and power affect projectile motion, collecting approximate values and recording results.
Introduction:
Parabolic motion has been studied for a long time dating all the way back to the time in which Galileo was conducting experiments. During the experiment two angles were fired at 320 and 100 at two different power levels and weights.
Galileo was the first person who accurately described projectile motion. Because of the drawings of Niccolo Tartaglia, Galileo realized that a projectile followed a curved path which is called a parabola. The parabola had an exact mathematical shape that was acted upon two forces, vertical and horizontal. His experiments included rolling balls down a highly polished inclined plane (to lower the acceleration) and record similarities. His work showed that horizontal motion experinces no...

...Projectile motion
into physics
Objective:
Our purpose for this lab was to observe projectile motion and use the equations of motion to predict the objects location in different instances of time. We used a projectile launcher and a ball to observe these properties of motion. The main equation used in this lab was d=Vit+1/2at^2 where Vit will produce the distance due to constant motion and 1/2at^2 will produce distance traveled due to accelerated motion or gravity in this case.
Introduction:
Projectile motion can be split into two separate dimensions of movement. The first being constant motion in the horizontal x axis witch neglecting air resistance should stay constant throughout the projectiles path. In the vertical y axis we have constant acceleration due to gravity toward the ground. These two motions are linked in time witch allows you observe the instantaneous characteristics of the projectile. Time is the connecter between the equations so you can salve for time in one equation and plug it into the other to find the data needed at that time/distance. Let's start by analyzing the horizontal x axis. Often the distance traveled by a projectile in the horizontal is called range(R = VicosÓ¨Ît). When broken down Vi cosÓ¨Ît is the initial velocity of the object in the x axis multiplied by how long it has been traveling at that speed equals your displacement in...

...Projectile Motion
Purpose: Apply the concepts of two-dimensional kinematics (projectile motion) to predict the impact point of an object as its velocity increases.
Introduction: The most common example of an object that is moving in two dimensions is a projectile. A projectile is an object upon which the only force acting is gravity. That is to say a projectile is any object that once projected or dropped continues in motion by its own, and is influenced only by the downward force of gravity. There are a number of examples of projectiles, such as
an object dropped from rest, an object that is thrown vertically upward, and an object
which is thrown upward at an angle to the horizontal is also a projectile. Since a projectile
is an object that only has a single force acting on it, the free-body diagram of a projectile
would show only a single force acting downwards; labeled force of gravity. Regardless of
which direction a projectile is moving, the free-body diagram of the projectile is still as
depicted in the diagram at the right.
In the case of projectiles, one can use information about the initial velocity and position of a projectile to predict such things as how much time the projectile is in the air and how far the projectile will go....

...object (stone, spear, arrow or bullet) is thrown, hurled or shot in the air, the object is a PROJECTILE (“Projectile”). The study of projectile is important because it must be realized that they are very much part of man’s daily life then and now. Whether man likes it or not, he encounters and uses projectile in his everyday life. Our hunting ancestors threw stones and spears on animals to kill them for their food.
In today’s sports, balls follow projectile motion such as when a basketball player shoots the ball into the hoop, a golfer or a baseball player hitting the ball, a tennis player lobbing the ball, a javelin thrower, a discus thrower or a shot putter trying to throw their objects as far as they can (Sears, Zemansky and Young 54). In warfare, catapults and arrows in medieval times were the deadly weapons while today, guns, mortars, rockets and missiles have replaced those ancient weapons of war (“Field Artillery and Mortars”, “Ballistics”). However, the way to effectively use these weapons has not changed. They are to be launched into projectile motion to hit the target. The path followed by a projectile is called its trajectory. Projectiles follow a curved trajectory or curved path that is a PARABOLA. (Sears, Zemansky and Young 54, Briggs 491).
It is actually easy to observe projectile motion when we...

Introduction
Parabolic motion has been studied for a long time dating all the way back to the
time in which Galileo was conducting experiments. In this lab report, the range a
foam disk launcher shot was tested by altering the angle of trajectory followed by
measuring the range. The range that the foam disk went was measured in
centimeters and multiple shots were taken at each angle and then averaged.
Galileo was the first person who accurately described projectile motion. Because
of the drawings of Niccolo Tartaglia, Galileo realized that a projectile followed a
curved path which is called a parabola.1 It was later found out by Galileo that the
parabola has an exact mathematical shape. Also, he stated that a projectile was
acted upon by two forces, vertical and horizontal. The vertical force was from
gravity, which pulled it to Earth at 9.8 m/s. That is why a parabola is a precise
mathematical equation.2
Observations were conducted before the experiment was started. First,
observations were made on two racquetballs, one being pushed from a table,
and another being...
