represents a force vs. time graph for the amount of force that was used to pull a wooden block across a table. As illustrated in Figure 1, the initial flat line in the graph represents the block at rest, this is where the forces acting on the object are the normal force, gravity, and the static frictional force. Force was then applied to the wooden block until it began to move, the point at which the block moves is the peak in Figure 1. This is the point at which there was enough force applied to the
When an object is dragged across a surface, the force of friction that must be overcome depends on the normal force as F=uN and the normal force is given by N= Wy, the vertical component of weight pointing perpendicular to the surface. When the angle of an inclined plane changes, the normal force changes and so does the friction. In this lab, you will change the angle of an inclined plane and observe how weight is resolved into its components, vertical (Wy) and horizontal (Wx) using the basic trig
Inquiry 2: Force with varied mass Introduction: In this inquiry the relationship between force and mass was studied. This inquiry presents a question: when mass is increased is the force required to move it at a constant velocity increased, and how large will the increase be? It is obvious that more massive objects takes more force to move but the increase will be either linear or exponential. To hypothesize this point drawing from empirical data is necessary. When pulling an object on the ground
The Effect of Weight on Sliding Friction Between a Block and Surface Planning ======== In this investigation we are going to find out what effect weight has on sliding friction. Friction is the force that is between two objects that are in contact with each other. The force is always present even though people only think it is there when the object is moving. Leonardo da Vinci was one of the first people to experiment with the idea of friction. He came up with two types of friction;
Introduction The purpose of this technical report is to communicate the results of the Pneumatic Tyre Characteristics laboratory by investigating the effect of cornering force on slip angle. The technical report is presented to the academic staff of the Engineering Systems Department at the Royal Military College of Science, Shrivenham. It is assumed that the reader is fully familiar with the experiment and with the equipment on which it is preformed. Experimental Conditions • For this particular
A connecting rod is a machine member which is subjected to alternating direct compressive and tensile forces. Since the compressive forces are much higher than the tensile force, therefore the cross-section of the connecting rod is designed as a strut and the Rankine formula is used. A connecting rod subjected to an axial load F may buckle with x-axis as neutral axis in the plane of motion of the connecting rod, {or} y-axis is a neutral axis. The connecting rod is considered like both ends hinged
The O.E soccer warehouse is a soccer warehouse that allows people to have great time playing soccer as well as buying soccer products we will have on display. Not only will our customers have the benefit of having a soccer place to buy products they need to play the game, yet they will also have soccer fields where people can have competitive games. Everything will be organized for tournaments for those people who have their own teams and want to win things. O.E soccer warehouse is the new version

In Raymond Carver’s story “Cathedral” the narrator learns what it means to “see” through someone who cannot. To see is to be able to view the things around us while putting aside preconceived notions or fear about these objects or people. In order for this to occur once must overcome what they feel is out of the ordinary and learn to accept things as they are. At first the narrator is doesn’t accept the man and uncomfortable around Robert. The narrator soon comes to understand this when he puts
Shaken Baby Syndrome (SBS) is an incident that will forever change and affect the victimized child dramatically. Most normal children are able to develop normally without deficits in areas of occupations or performance skills, but a child with SBS may never be the same. The lasting effects of Shaken Baby Syndrome impact a child’s life in areas of occupations such as social participation, play, and education. Characteristics of Shaken Baby Syndrome Etiology Shaken Baby Syndrome is, “a condition of
same class. One student is normal in abilities and the other has a learning disability. The second student suffers from dyslexia. The students in the class are expected to listen to the teacher and to take notes. The normal student would be able to read and write efficiently. However, the dyslexic student would have a hard time not only reading the board presentations but in taking notes. This would cause the dyslexic student to not be able to learn as much as the normal student. This scenario does

But, to dream of baboons and periwinkles, is what we should strive to dream of. These things are what the drifters, like a sailor, dream of. He uses the sailor image to convey the individual in society who doesn't live the normal life. He could have replaced this image with a number of other names referring to a non-traditional lifestyle, but only chose

This is because Bisclavaret is far from a normal person or animal, however, he is the best friend and protector the king could ask for. He is better than any knight or normal animal on the Earth. The last message that was portrayed in the story is that cheaters never win. The wife literally cheated on her husband and

Greg and Earl were then talked into creating a “It seeks the unconventional over the normal because life doesn’t ever play fair or normal,” said Donald Shanahan from Every Movie has a Lesson. I genuinely agree with him because throughout the film Greg constantly says Rachel won’t die. However, you cannot trust him based off of his experience with marijuana.
friction. The forces associated with gliding are fairly straightforward: gravity, friction, and air resistance. Air resistance has several inputs that add to the total resistive force. Friction is caused by the lack of a perfectly smooth surface between the skis and snow on a microscopic level. Think of it as the Rocky Mountain range trying to slide over the Himalayas. On a microscopic level this is what friction is. Two factors contribute to the resistive frictional force; a normal force and the friction
skydiving has grown from a madman's fantasy to a international sport. As a skydiver stands at the door of the airplane, the force of their mass multiplied by gravity is directly countered by the force of the plane pushing back up on their feet, this is know as the normal force and is shown is the equation FN = m * g As soon as the the diver exits the plane, the normal force is removed and the diver begins to fall. Generally, a skydiver will exit the airplane at about 13,000 feet (4000 meters)
the sport of downhill skiing. m = mass of skier g = gravitational force a = acceleration mu = kinetic friction coefficient · Inertial Forces = (m)(a) · Frictional Force = (mu)(m)(g)(cos theta) · Graviational Force = (m)(g)(sin theta) Gravity is the force that holds the skier to the ground and is also what pulls the skier down the hill. While gravity is acting straight down on the skier, a normal force is exerted on the skier that opposes gravity. As the skier skis down the hill
affect the force of friction through experiments. The objective was to understand how the coefficient of friction is derived from the normal force and force of friction and to determine if the area of contact between the surfaces produces different values for the forces of friction. Frictional forces are ones that oppose motion when two surfaces are found in contact with each other. Friction is a force acting parallel to two surfaces in contact. If the object is in motion, the friction force always acts

A steel ring (7) serves two purposes: it protects the sides of the snowboard and puts maximum force into the snow for optimum maneuverability. The graphic layer (2) is a printed layer of fiberglass giving the snowboard an appealing design. There are literally millions of different snowboards with a unique graphic on them, but snowboard consumers
