When an 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...

Part one: The Lab 1. You will be helping Galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. Before you conduct your experiment, you need to form a hypothesis. A hypothesis is a prediction of what you think will happen in the experiment. The hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. Record your...

Force: This can be defined as a pushing or pulling action that causes a change of the state of a body. A long jumper who wants to increase their degree of force will need to increase their weight, but this can negatively affect their speed, so it is vital to get the balance right. The law of reaction also applies to movements that occur in the air. In these situations the equal and opposite reaction is shown in movements of other parts of the body. A long jumper, for example, will bring the...

Uniform Circular Motion Uniform Circulated Motion is defined as a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation (and constant speed), or non-uniform with a changing rate of rotation. The rotation around a fixed axis of a three-dimensional body involves circular motion of its parts. The equations of motion describe the movement of the center of mass of a body. Physics, particularly...

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction resists relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into static friction ("stiction") between non-moving surfaces, and kinetic friction between moving surfaces. Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each...

How Guns Work A gun is a weapon that uses the force of an explosive propellant to project a missile. Guns or firearms are classified by the diameter of the barrel opening. This is known as the calibre of the gun. Anything with a calibre up to and including . 60 calibre(0.6 inches) is known as a firearm. The precise origin of the gun is unknown, although they were in use by the early 14th century and were common place in Europe by mid-century. These early guns were nothing more than large...

Pre-lab: Newtons Three Laws of Motion: There are three laws of motion that have been stated by Sir Isaac Newton during the sixteenth century that are looked upon even today. The first of these laws states that an object will stay in at rest or in a constant velocity unless a force acts upon it. In simplest terms this means that if u place an apple on the table it isn't just going to roll off. The second of these laws states that when a force acts upon an object it causes it to...

In physics, motion is a change in position of an object with respect to time and its reference point. Motion is typically described in terms of velocity, acceleration, displacement, and time.[1] Motion is observed by attaching a frame of reference to a body and measuring its change in position relative to another reference frame. A body which does not move is said to be at rest, motionless, immobile, stationary, or to have constant (time-invariant) position. An object's motion cannot change...

Centrifugal force Centrifugal force (from Latin centrum, meaning "center", and fugere, meaning "to flee") is the apparent outward force that draws a rotating body away from the center of rotation. It is caused by the inertia of the body as the body's path is continually redirected. In Newtonian mechanics, the term centrifugal force is used to refer to one of two distinct concepts: an inertial force (also called a "fictitious" force) observed in a non-inertial reference frame, and...

Objective: To study the conservation of energy and momentum using projectile motion. Theory: The ballistic pendulum demonstrates both the constant horizontal velocity in projectile motion and the conservation of momentum. Because there is no acceleration in the horizontal direction, the horizontal component (v_x) of the projectile’s velocity remains unchanged from its initial value throughout the motion. In a closed isolated system, if no net external force acts on a system of particles, the...

Newton’s Cradle Isaac Newton was a key figure in developing some basic laws of motion that apply to the world all around us. One object that demonstrates some of Newton’s Laws of Motion is Newton’s Cradle. Because Newton’s Cradle was not invented by Newton, the name is a bit misleading. Although there is still some confusion today as to who is the rightful inventor of this object, most sources claim that Newton’s Cradle was invented by Marius Morin and was later coined “Newton’s Cradle” by...

Freefall and Projectile Motion Introduction and Objectives This lab experiment was done to determine the characteristics of free fall and projectile motion in Physics. The motion in which a body is thrown or projected is called Projectile motion while free fall is any motion of a body where gravity is the only force acting upon it, at least initially. In this experiment, a photogate, a chopper, and a Universal Lab Interface were used to determine the free fall motion of the chopper as it...

Physics is how everything in the world works in harmony. Without it, things would be floating around, the earth wouldn’t rotate, and it’d be a huge mess. Newton’s laws of physics are the best way to explain how the physical world works. Newton’s first law of motion states “an object at rest will remain at rest and an object in motion will continue moving at a consistent velocity unless acted upon by a net force. A real world example of this would be playing golf. The golf ball sits on the...

Physics in Sports Introduction Billiards, Pool or 8 Ball are the names given to this game. For many of us 8 Ball is a game that we play at friends' place or at pool houses, pubs and a good many other places. But when you are playing 8 Ball you would never really think about physics would you? But it is there, and it is in play everytime the cue hits the ball to make it curve, everytime you jump the ball over another or bounce it around the cushioned sides to get the white...

An air track is an apparatus that simulates the effects of frictionless motion. A known mass is attached to an air-cart on an air-track apparatus. Attached by string, the air-cart is pulled by the known mass when hung over a pulley. A spark timer will mark the motion at a frequency of 10 Hz (10 dots/s) on a strip of paper called ticker tape. The air-track will supply air through the apparatus to simulate a frictionless environment, enabling the system of masses to move without an applied force...

NEWTON’S SECOND LAW: ATWOOD MACHINE Introduction One may study Newton’s second law using a device known as Atwood’s machine, shown below. It consists of a pulley and two hanging masses. The difference in weight between the two hanging masses determines the net force acting on the system. This net force accelerates both of the hanging masses; the heavier mass is accelerated downward and the lighter mass is accelerated upward. This system is convenient for studying motion under constant...

Roller Coaster For many people, there is only one reason to go to an amusement park: the roller coaster. Some people call it the "scream machine," with good reason. The history of this ride reflects a constant search for greater and more death-defying thrills. How does a roller coaster work? What you may not realize as you're cruising down the track at 60 miles an hour is that the coaster has no engine. The car is pulled to the top of the first hill at the beginning of the ride, but...

Free Fall Rachel Shea Physics 131 Lab, QL Hasbrouck 210 Sept. 21, 2014 Abstract This experiment measures the study of motion by observing the force of gravity acting solely upon an object, and also measures reaction time. If an object is in free fall, the only force acting upon it is gravity. The object used in this experiment was a golf ball that provided some acceleration when dropped. A sensor positioned underneath a table recorded the golf ball’s pattern of motion, when dropped. The...

Newton's Second Law Lab Preliminary Questions 1. When you push on an object, the magnitude of the force on the object directly affects it's motion. If you push harder on the object, it's motion is larger. 2. If we have a bowling ball, and a baseball each suspended from a different rope, and hit each ball with a full swing of a baseball bat, the ball that will have the greatest amount of change in it's motion will be the baseball. This is true because the baseball has a smaller mass than a...

The biomechanical principle : Principle #1- Stability The lower the centre of gravity, the larger the base of support, the closer the line of gravity to the centre of the base of support, and the greater the mass, the more STABILITY increases. There are two types of stability: 1.) Linear a.) Static- at rest a person stability is proportional to the mass and the frictional forces between the person and any supporting surfaces. b.) Dynamic- While moving a person's linear...

Physics can simply be defined as the science that studies the mechanics of matter, motion, energy, and force. Dance in my opinion is a type of performance categorized as a form of art that involves the mind, body, soul, and a little something called physics. Dancing is a personal favorite hobby of mine, but I’ve never really considered the physics side of dancing which seems odd considering all the different movements and techniques that involve many principles of physics such as rotational...

Isaac Newton founded classical mechanics on the view that space is distinct from body and that time passes uniformly without regard to whether anything happens in the world. For this reason he spoke of absolute space and absolute time, so as to distinguish these entities from the various ways by which we measure them (which he called relative spaces and relative times). From antiquity into the eighteenth century, contrary views which denied that space and time are real entities maintained that...
