fluid cannot‚ any shear stress applied to a fluid will result in the motion of that fluid for as long as the shear stress is applied. τ=FA Where F = force which is tangent to a surface (shear force)‚ A = area of moving plate in which shear force is applied to. Velocity gradient – is the change of velocity with distance. If applied shear force is changed‚ the shear stress is also changed‚ which results in a new velocity gradient being established. dvdy Boundary conditions of fluids in contact

following Factors will affect the distance the tub can travel: · Surface area of the tub · Air Resistance · Force applied to propel tub · Length of elastic bands used to propel tub · Surface on which tub will travel Prediction I predict that as the mass of the tub increases‚ the distance the tub can travel will decrease. This is because of friction. Friction is the force that resists the relative motion or tendency to such motion of two bodies in contact. Each time the mass of the tub

energy to a second object‚ then the first object does work on the second object. Work is the application of a force over a distance. Force‚ on the other hand‚ is equal to the weight of the object‚ and the distance is equal to the height of an object. Energy can be defined as the capacity for doing work. The simplest case of mechanical work is when an object is standing still and we force it to move. The energy of a moving object is called kinetic energy. Power is the work done in a unit of time

years of age‚ they are helpless in withstanding crash forces as well as adults; henceforth they should remain rear facing. In a crash‚ severe or deadly injuries are generally limited to the head and neck‚ in the case of a child being in a harnessed seat. When a child is in a forward facing seat‚ there is an incredible amount of stress put on the child’s neck‚ which must hold the large head back. A small child’s neck upholds great amounts of force in a crash. The straps hold the body back while the

Marketing environment consists of the actors and forces that affect a company’s capability to operate effectively in providing products and services to its customers and the marketing environment includes both the micro-environment and macro-environment. On the one hand‚ the micro=environment is the internal environment and operations stakeholders such as suppliers‚ employees and retailers over which the company has a degree of control. This shows the micro-environment is inside the company’s control

ABSTRACT The purpose of this project is to determine the effect the size of an automobile’s wheel radius will have on that vehicle’s performance. To determine this‚ the distance a car travels when tested with the same propulsion force but different wheel diameter is measured. We expect that there will be an optimum size that should be utilized in order to achieve maximum efficiency. A larger or smaller wheel size should change the distance that the car will travel. The cars we

serves to examine and evaluate the physical forces that affect the flight of a bottle rocket. This will be accomplished by altering the water levels and the level of air pressure (psi) within the rocket will be altered‚ and tested‚ to further understand the mechanics of bottle rockets. Introduction Rocket flight has long been at the forefront of the human race’s exploration of our universe. This undeniable fact makes it necessary to study and examine the forces that act upon rockets as the fly. Given

Acceleration Due to Gravity Conducted on October 6th‚ 2014 Objective: The object of the experiment is to determine whether or not objects fall freely at the same rate and speed. Measure and calculate the time in which it takes random objects to hit the ground from a certain height and determine if the objects have the same rate of motion or not. Materials: 1. Meter Stick 2.
