This study focuses on the different factors that affect the game results of the throwing events namely, javelin throw, discus throw, and shot put throw. It is observed that during athletic meets, the winner is determined by the farthest throwing distance. However, this distance does not sum up the outstanding performance of a winning athlete. Several factors are deemed to be essential in strategically winning a throwing event. For instance, an athlete may need more effort in performing as compared to another because of certain physical or strategic hindrances. These hindrances seem to be inexistent when a game is analyzed using the distance covered only.

Thus for the purposes of this study, the competition outcome is defined to be the resulting projectile from the throw. In analyzing the projectile, the research is opened to the influences of strategies beyond throwing the farthest. These factors can be grouped into three aspects: the thrown object’s standard measures, the strategy, and the player’s characteristics. First, the projectile allows us to examine the effects of the thrown object’s standard measures to the throwing ability of a player. These measurements include the weight of the object, and its circumference, in the case of the shot put and the discus, or its length, in the case of the javelin. Second, the projectile exposes the possibility of implementing various strategies that may affect the throwing distance, such as the angle of the throw and the velocity of the turn, in the case of the shot put and discus throw, or run, in the case of the javelin throw. Finally, the projectile also somehow illustrates the advantages or disadvantages of the player’s characteristics like height, weight, and body-build.

Consequently, the research will not be tied to the distance results of the throwing events. Rather, it will be concerning thee different projectile elements – distance, height, angle, and force – as they are influenced by...

...ProjectileMotion
Experiment # 4
Introduction:
ProjectileMotion 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 projectilemotion 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 projectilemotion and ability to understand trial-to-trial variations in the velocity measurement when calculating the impact point.

Objectives:
Students will measure the maximum height H and the range R of a projectilemotion.
They will study the effect of the shooting angle on H and R.
Material used:
4 rulers, track, metallic ball, landing track, A4 white paper, red carbon paper, timer + supply, gun
+ protractor.
Theory:
A projectile is an object upon which the only force acting is gravity. There are a variety
of examples of projectiles: an object dropped from rest is a projectile (provided that the
influence of air resistance is negligible), an object thrown vertically upwards is a
projectile (provided that the influence of air resistance is negligible), and an object
thrown upwards at an angle is also a projectile (the same assumption). A projectile is
any object, which once projected, continues its motion by its own inertia and is
influenced only by the downward force of gravity.
By definition, a projectile has only one force acting upon - the force of gravity. If there
were any other force acting upon an object, then that object would not be a projectile.
Projectiles can be launched both horizontally and vertically, and they have both
horizontal and vertical velocity and horizontal and vertical displacement.1

ProjectileMotion
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 projectilemotion. The purpose of the experiment was to conduct a first-hand investigation to design and analysis how angle, weight and power affect projectilemotion, 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 projectilemotion. 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...

Objectives: Using a projectile gun on an incline plane, calculate the
velocity of the steel ball at ten different distances, then find the average
velocity. In order to find the velocity of the steel ball two different
equations are needed. In order to find the velocity of the steel ball fired
from the projectile gun on an inclined plane, the first equation must be
manipulated and substituted into the second equation. Then use the average
velocity to determine the distance of a projectile being released at a different angle.

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 projectilemotion. 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...

ProjectileMotion
Objectives:
The purpose of this experiment is to examine the projectilemotion of a ball launched horizontally. The initial velocity will be calculated. The range of the ball will be measured.
Theory:
Horizontal launch of the ball allows computing the initial velocity v0 by measuring the height of the launch and the distance traveled by the ball:
h=, s=v0 ∙ t
Solving these parametric equations for v0 gives us:
0=s
Where h and s are defined from the experiment
Equipment:
*projectile launcher and plastic ball
*carbon paper
*white paper
*meter stick
*tape
*stand with a clamp
Procedures:
1. We set up the projectile horizontal position.
2. We measured for the height at which the ball will be launched. h=0.310m
3. We put the plastic ball into the projectile launcher and charged it for the short range launch.
4. We made a test shot to determine the position of a sheet of white paper covered with a carbon paper.
5. We taped the sheet of white paper to the area of a ball landing.
6. We made five shots of the ball.
7. We measured the distance (range) of the ball motion on each trial, and the height it was launched from.

...ProjectileMotion
The purpose of this lab is to study the properties of projectilemotion. From the motion of a steel ball projected horizontally, the initial velocity of the ball can be determined from the measured range. For a given initial velocity, the projectile range will be measured for various initial angles, and also calculated by applying the theory for motion with constant acceleration. For further background information, refer to the sections in your textbook on projectilemotion and motion with constant acceleration.
THEORY For a given initial velocity, v0 , and initial position, s0 ,the position of a particle, s, as a function
of time, undergoing constant acceleration, a is given by sr = sr 0 + vr 0 t + 12 ar t 2 ( 1 )
This is a vector equation and can be broken up into its x, y, and z components. Since the motion is in a plane, we need only look at the x and y components. If we neglect air resistance, the acceleration in the y direction is -g, due to gravity. The acceleration in the x direction is zero. Hence, the vector equation (1) becomes two scalar equations:
If we eliminate t in Eqs.(5) we get y as a function of x. gx2
and solving for vo we get
x = x0 + v 0x t (2) y=y+v t-1gt2
0 0y In terms of the angle θ, and the initial speed vo, the initial velocity components are
v0x=v0cosθand v0y=v0sinθ...
