The Coefficients Of Static And Kinetic Friction

- The objective of this lab is to determine the coefficients of static and kinetic friction between a block of wood and wooden table. It was hypothesized that the mass of the object would not impact the coefficient of friction. It was also hypothesized that the coefficient of static friction would be larger than the coefficient of kinetic friction. Introduction Friction is a force between two surfaces that provides traction to conduct most human activities. At a microscopic level, all surfaces are rough, and when they slide against each other, there is a resistance to slide that needs to be overcome by the application of a force....   [tags: Friction, Force, Classical mechanics]

The Resistance Of Motion By Static And Kinetic Friction

- The purpose of this experiment is to analyze the nature of the resistance of motion by static and kinetic friction. First, the maximum static friction force is attained through a system comprised of a mass hanging from a string nestled on a pulley and attached to a block and force sensor. Secondly, a block is moved at constant velocity to determine what force in the positive direction will match the force of kinetic friction in the opposite direction. Thirdly, data is collected from an accelerating block in order to calculate net force on the body, including the kinetic friction force....   [tags: Friction, Force, Classical mechanics, Mass]

Friction and Dynamics of Rock Avalanches Travelling on Glaciers

- ... This indicated that the friction coefficient of a rock avalanche on a glacier was not constant. Before constructing the model, preconditions were established from simple experiments that determined the basic attributes of solid objects travelling on ice. The preconditions were that heavier weight caused more energy to dissipate and a larger layer of lubrication (therefore less friction). Rock sliding on ice behaves in a similar way to a rough metal sliding against a soft metal. In both cases, one digs grooves in the other, (and the rate of erosion is dependent on the angle at which the grooves are dug.) Through collecting data quoted in other studies with regard to friction’s role in r...   [tags: history, collection of data]

- The Factors Affecting the Stopping Distance of a Margarine Tub Aim: To investigate the factors that affect the stopping distance of a catapulted margarine tub. In this experiment, I will be concentrating on the effect that varying the mass of the catapulted tub has on its stopping distance (sd.). Introduction: Things that move eventually have to stop. However, where they stop depends on several factors- their mass (the mass of the moving object), the speed the moving object is going at, the friction between the surfaces and the air (or water) resistance and movement around the object....   [tags: Papers]

Physics in Computer Games

- Physics is one of the key elements of any computer game or animation. This is especially true, when it comes to 3D environments. Physics applies to every aspect of the real world, from how objects act on each other through obvious collisions down to the more in depth conservation of energies and momentums. These same concepts apply to Computer Generated Environments (CGE). 3D CGEs always require a few key laws to be followed in order for them to look at least somewhat realistic. Without at least implementing these simple physics concepts, the interaction of polygons will look unrealistic....   [tags: Physics video games computer]

Investigating Force And Acceleration Is Expressed By Newton 's Second Law Of Motion

- Investigating force and acceleration Background The relationship between force and acceleration is expressed by Newton’s second law of motion which states that “the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. “ (The Physics Classroom, n.d.) This law can be expressed as the equation F= ma, where F is the net force, m is the mass and a is the acceleration....   [tags: Force, Mass, Newton's laws of motion]

Deep Foundation: Bored Pile Construction

- DEEP FOUNDATION Deep-foundation elements comprise piles and piers and are like slender columns buried in the ground. They are prevented from buckling because they are confines by the soil. Piles and piers transfer the load either to bedrock or to soil of high bearing capacity while passing through unsuitable soil. As previously stated, deep foundation are used where shallow foundation cannot be used because the topsoil is expansive or has a low bearing capacity or where the frost line is deep. They are also used in buildings that house items or instrumentation sensitive to settlement of shallow foundations....   [tags: civil engineering]

Physics of Bicycles

- Physics plays a vital role in all that we do, whether we are aware of it or not. The sport of bicycling is no exception to the physical laws of Mother Nature. Friction is a resistive force that always acts in a direction that is opposite to the motion of a body. Frictional forces are dependent on two components; the coefficient of friction and the normal force. Friction = (µ)(n) There are two different types of frictional coefficients, static and kinetic. The coefficient of static friction is the frictional force that must be overcome before any motion commences....   [tags: physics bike bicycle cycle]

There are many factors that come into play when a car collision occurs, however only one factor stays constant throughout every single collision, and that is the laws of physics. The laws of physics are the fundamental base of understanding the world we live in, but unfortunately many people seem to be completely oblivious to them. A lot of the time, we try to deny our ignorance to physics but usually end up proving the opposite.

Physics of Stopping a Bike

- In short brakes are a tool that turn kinetic energy into heat(http://en.wikipedia.org/wiki/Brakes). This is accomplished by applying friction in one way or another. In the case of disk brakes friction is created because the braking mechanism exerts a force on the break pads which pushes them into contact with disk. It is this contact combined with the fact that the disks are rotating that causes kinetic energy to be converted to heat. If the purpose of brakes is to convert kinetic energy into heat, then in order to know how much heat the brakes make requires that we find out how much kinetic energy there is in a moving bicycle....   [tags: physics bicycle]
