work on the principles of gravity and air resistance and in effect‚ terminal velocity. Air resistance (air friction) Air resistance is an upward force exerted on a body while it is in the air and is the result of air molecules that come in contact with the surface of the falling object. This force attempts to counteract gravity and other downwards forces influencing a body. The amount of air resistance encountered by an object is dependent on two factors: speed of the object and surface area. Air

The Five Competitive Forces Model In this section‚ the structure of our company will be explained using the five competitive forces model developed by Harvard professor Michael Porter. These forces include: rivalry among existing firms‚ threat of new entrants‚ bargaining power of buyers‚ threat of substitutes and bargaining power of suppliers. Each of these forces will have their own distinctive effect on determining industry profitability. Intensity of rivalry among competitors: Recently there

systems all forces and torques sum to zero. In problems where the first and second conditions of equilibrium are satisfied‚ the best strategy is to create FBD’s for both the first and second conditions‚ derive equations based on these FBD’s and then see what useful information may be gleaned from these equations. When applying the second condition we are free to choose any axis about which to compute torques. It is best to choose an axis that eliminates one or more forces that have lines of force that pass

Six Forces Porter’s forces analysis is a framework for industry analysis and business strategy development that draws upon industrial organization economics to determine the competitive intensity and overall industry profitability. These forces are 1) potential entry of new competitors‚ 2) bargaining power of suppliers‚ 3) bargaining power of buyers‚ 4) substitute products‚ 5) rivalry among competing sellers in an industry‚ and 6) power of stakeholders. A change in any of the forces normally

0m. Neglecting friction between the car and road‚ find (a) v and (b) the horizontal force exerted on the car. 25) A daredevil on a motorcycle leaves the end of a ramp with a speed of 35.0 m/s as in the figure P5.25. If his speed is 33.0 m/s when he reaches the peak of the path‚ what is the maximum height that he reaches? Ignore friction and air resistance. 31) A horizontal spring attached to a wall has a force constant of 850 N/m. A block of mass 1.00 kg is attached to the spring and oscillates

load (vertical). It resists the applied loading by a combination of internal transverse shear force and bending moment. An accurate analysis required in order to make sure the beam is construct without any excessive loads which affect its strength. A bending moment exists in a structural element when a moment is applied to the element so that the element bends. Moments and torques are measured as a force multiplied by a distance so they have as unit newton-metres (N·m). The concept of bending moment

Physics Notes * If the vector of all sums is precisely zero the object could be still moving * IF an elevator fell ‚ the passengers would be trapped to the ceiling of the elevator seeing as there is no air resistance ‚ false * Constant speed = no acceleration = sum of all net forces is zero * An object in orbit around the earth is not truly weightless * Sitting half as far away from your class mate the gravitation force is four times as strong.

there is a constant relationship between these forces. Lift is the upward force created by the effect of airflow as it passes over and under the wing. The airplane is supported in flight by lift. Weight‚ which opposes lift‚ is caused by the downward pull of gravity. Thrust is the forward force which propels the airplane through the air‚ which varies with the amount of engine power being used. Opposing thrust is drag‚ which is a backward‚ or retarding‚ force which limits the speed of the airplane. I’m
