The purpose of this project is to better understand the effectiveness of the sling in hunting and combat...**projectile** weapon that was used in ancient times for purposes of protecting herds, hunting, and combat (York and York 2011: 56-59). Fundamentally, sling was used as a hand-on weapon that was fired by the use of the arm. Users loaded the sling with offensive pellets that included stones and clay. The carriers then spanned the sling in their arms till they felt they had gathered enough force or pressure in the sling before finally releasing it towards their enemies. A very popular story of the use of the sling is told in the story of David and Goliath, where we are told that David used a sling to project a stone against Goliath. There is a lesson learnt from slings here and that is, slings were very powerful weapons and...

Ballistics...(Pender, 2012). The ballistic coefficient of a bullet (G1) allows an individual to scale the bullets drag to the standard **projectile** established by the Gavre Commission. The standard ballistic coefficient of a bullet established by the Gavre commission was 1.000 (Warlow, 2012). This standard allows an individual to calculate how many feet’s a **projectile** will lose a given number of velocities in comparison to a distance a standard **projectile** will cover, after losing the same amount of velocity, under similar atmospheric environment. For example, a G 1 standard **projectile** drops approximately 2904 to 3000 fps over a distance of 100 yards. This is at a standard...

Investigating the physics of basketball...Investigating the Physics of Basketball Introduction This paper explores specific principles of physics that find application in basketball. The principles include **projectile** motion and gravity, moment of forces and stability, momentum and collision and viscous drag. It examines how equations related to these principles can be used to improve the game of basketball or make decisions. **Projectile** motion equations can be used to determine optimal angle at which the ball can be thrown in order to score. Moment of force and stability can be used to calculate critical angle at which if a player tilt past, he or she falls. Concepts of momentum and collision are helpful in studying the behavior of ball when it...

Woven Textile Design...Modern weaving machines contain shedding devices and pick insertion systems. Available shedding devices are tappet, dobby and jacquard shedding. Pickinsertion systems available in modern weaving machines include weft transfer using **projectile**, rapier and air-jet. These modern weaving technologies made possible the availability of wide range of weaved fabrics with different composites for different purposes.
Shedding involves lifting some of the warp yarns to form a "tunnel" through which the yarn is inserted. There are three sorts of shedding mechanism - tappet, dobby and Jacquard. Tappets are used for simple weaves in which the number of shafts is limited. Dobby systems involve the use of a pattern chain to control the lifting... repeat....

Lab report...Lab report Prediction of the Maximum Height Travelled By a Model Rocket The determination of rocket field is useful when in the quest for determining how high a rocket flies, at a given moment. In this lab, the major objective was to predict how high a rocket model could fly once launched. This involved acquiring a model rocket, then launching it to determine the figures for the various variables. Another related objective was to apply equations for basic **projectile** motion in determining how high a rocket can fly. Since launching the model rocket, this is considered a **projectile** motion influenced by height of launch pad, gravity and velocity imparted by the engine. Consequently, there was need for...

Projectile Motion... **Projectile** Motion This refers to the motion under the effect of gravity. This experiment is going to investigate four aspects of **projectile** motion.
Objectives of the experiment
1. To show that horizontal and vertical components of motion can be treated separately
2. To show that the horizontal motion takes place at constant velocity
3. To show that the range is the same for complimentary angles
4. To show that the trajectory is a parabola
Discussion of the four aspects of the experiment
The first part was the experiment following the procedure in part 3.1 was meant to verify that the ball launched at different speeds hit the ground at the same time interval after being shot while the range will depend on the initial velocity... that is...

Lab report...Physics lab report Purpose The aim of this experiment is to compare experimental results for **projectile** motion in two dimensions, using a meter stick and a spring-loaded gun, with theoretical calculations.
Introduction
**Projectile** motion is the motion experienced by an object in two dimensions due to its attraction of the earth, air friction ignored. It is the superposition of two independent motions in x- and y-directions. The motion in the x-direction is uniform meaning that there is no acceleration since the velocity is constant (Serway, Vuille & Faughn, 65).
ax = 0.
vx= v0x
x = vxt.
The motion in the y-direction is a free fall.
ay = - g vy = – gt
Dy = - ½ g t2
Since the velocity = 0 ( voy =...

Investigation#4:Initial Velocity of a Projectile... A **projectile** is any object that is cast, heaved, hurled and pitched or thrown from space or from the atmosphere. The path of a **projectile** is called its trajectory. An example of a **projectile** can be a moving airplane in the air with its engines and wings disabled. The force acting on the **projectile** is known as gravity the effects of other forces are minimal. **Projectile** usually has an initial non-zero horizontal velocity whose acceleration is due to gravity alone. An object can also ceased to a **projectile** once any real effect is made to change its trajectory
Total time for which the **projectile** remains in the air is called Time of flight.
After the fight, **Projectile** returns to horizontal axis, so y=0
The assumption here is that air... is...

Chemical Engineering, physics...such as biotechnology, food and beverages, mining, pharmaceuticals, tire and rubber, and many more. Chemical engineers are an integral part of advanced space programs in NASA. Thus, chemical engineering is the most versatile branch of engineering that finds its presence in almost every field.
Kinematics with Constant Acceleration and **Projectile** Motion
Newtons laws clearly explain the changes in the state of motion of objects at rest or moving in single dimension. Kinematic principles can also explain the motion of objects in two dimensions such as **projectiles**. Gravity is the only force that applies on a **projectile** while set in motion assuming air...

Maximum height of a projectile motion...Maximum height of a **projectile** motion The essence of this experiment was to investigate for the maximum height that can be reached by a **projectile** motion. From the motion of the two balls projected horizontally, the balls are projected at the same initial velocity and same angle of elevation. The data was tabulated, and graphs were drawn and analyzed to find the dependence of maximum height reached by a body in **projectile** on initial velocity and angle of elevation.
Introduction and background
According to the fundamental laws of physics, when a body if projected into the air, its trajectory motion in determined by the Earths pulls of gravity. Since the gravitational pull acts downwards...
