Eighth Air Force

(acceleration) is proportional to the net force and inversely proportional to the mass. Background Theory: Sir Isaac Newton presented his three laws of motion in the Principia Mathematica Philosophiae Naturalis in 1687. The second law, ΣF = ma, states that changes in force will cause an object to accelearate and with this equation, one can figure out how much. It can be rewritten into a = ΣF / m, and thus, it can be seen that acceleration is proportional to net force and inversely proportional…

Dynamic Traction Control (DTC) is a sub-function of the Dynamic Stability Control (DSC) system that can be turned on and off. DTC has two major roles: to regulate traction and to enable sports-style driving while providing active stability control. When the drive wheels start losing traction the DSC automatically begins stabilisation measures. The Dynamic Stability Control system curbs the engine output and stops slip on the wheels. In exceptional situations, however, a small amount of wheel…

Equilibrioception is the sense of balance and a process that takes place within the body. Balance is maintained by the human body during both normal posture and movements. Thus, equilibrioception is a continuous process that takes place unconsciously in the body for the most part. This procedure requires the input of information from the vestibular, visual and proprioceptive systems. Motor output is relayed through two separate pathways in response to the integration of the information. Thus,…

acceleration and there must be an external force causing centripetal acceleration. As shown in the diagram, the only thing in contact with the car is the road, which is between the tyres of the vehicle and the surface of the road. Therefore, we can know that the frictional force exerted between the tyres and the road directed to the centre of the arc of which the car is travelling, is the causative force for centripetal acceleration. F= Frictional force between tyres and road F=ma^c F=(mv^2)/r…

This will determine the force that can be generated within the muscle. The greater the strength required, the greater the number of motor units (and therefore the number of muscle fibres) that contract. Stimuli too weak to produce a spike do, however, set up a local electrotonus…

Degenerate Cases of Conic Sections: Conics are formed when a plane and a double cone intersect. These intersections can form a variety of conics. These include: circles, parabolas, ellipses and hyperbolas. A circle can be formed from a cone if a plane intersects with the cone at an angle perpendicular to the base of the cone. This circle is also formed by the equation: (x-h)2+ (y-k)2=r2. This equation creates a relation because the collection of points does not pass the vertical line test. To…

defining the coaster To create a replicated graph of the formulas To determine the maximum height of the coaster as well as the longest drop, in comparison to other great coasters in the world To determine how long the passengers will be in the air, how fast the coaster is going when hitting the “splashy zone”, and where the “splashy zone” should be built To determine the maximum height a passenger can reach during this ride, and how long it takes to reach that height. The values of the…

The larger draft both causes an increase in water resistance, due to the stern having a larger surface area, and a decrease, due to this larger draft leading to a larger buoyant force, causing the boat to float higher. Deducing whether the decrease in resistance is greater than the increase can only be accurately done through experimentation. HYPOTHESIS The main hypothesis being investigated is that a more buoyant boat will have…

uniform motion in a straight line, unless is compelled to change that state by forces impressed upon it’ (McGinnis, 2013, p.88). Simpler, the law of Inertia says that if there is no external force acts on a subject, that subject will not move and it will remain in states of rest or if it was moving it will continues moving at constant speed in the straight line. Gravity based on Frank Bell (1998) is an external force that acts on all objects that are near to earth. This is the conclusion of all…

this experiment to be very interesting since I’ve seen and used pendulums a lot before, but I have never really reflected on why they oscillate. After this lab and understanding of the theory, I even know how to relate measurements to figure out the force of gravity. That is why I love physics, everything is related which makes it possible to explain phenomena seen in the everyday life.…
