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. Materials:

Computer plumb bob
Vernier computer interface ramp
Logger Pro two ring stands Two Vernier Photogates two right-angle clamps Ball(1 to 5 cm diameter) meter stick or metric measuring tape Masking tape target

Procedure:
1) Set up a low ramp made of angle molding on a table so that a ball can roll down the ramp, across a short section of table, and off the table edge. Position the Photogates so the ball rolls through each of the Photogates while rolling on the horizontal table surface and not on the ramp. 2) Mark a starting position on the ramp so that you can repeatedly roll the ball from the same place. Roll the ball down the ramp through each Photogate and off the table. Catch the ball as soon as it leaves the table. 3) Open the file “08 Projectile Motion”. A data table and two graphs are displayed; one graph will show the time required for the ball to pass through the...

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:
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

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
Purpose: Apply the concepts of two-dimensional kinematics (projectilemotion) 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...

...ProjectileMotion Lab Report
Objectives:
This laboratory experiment presents the opportunity to study motion in two dimensions, projectilemotion, which can be described as accelerated motion in the vertical direction and uniform motion in the horizontal direction.
Procedures and Apparatus:
|Rubber Ball |White sheets of papers |
|Metal Track |Water |
|Books |Table |
|Meter-stick |Stopwatch |
• Obtain all the apparatus and material needed to proceed with experiment
• Set up a ramp using the metal track and a bunch of books at any angle so that the ball will roll off.
• Measure the distance from the edge of the table to the end of the ramp.
• Roll the ball down the ramp and off the table but make sure to catch the ball as soon as it leaves the table; do this part 10 times and record the times
• Calculate average velocity for this step
• Measure the height (vertical distance or the y-axis) of the table.
• Using this height, derive t (time) from the uniform accelerated motion in order to obtain the predicted distance x.
• The next step is to release the ball from the ramp and let it fall off the table to the floor.
• Measure the spot on the floor where the ball hits the...

...Investigating Projectiles
Background:
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. Projectilemotion 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 projectilemotion 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...
