Breaks are not something people take the time to think about. Even if they are fundamental to the vehicles many people use every day. The functionality of breaks is contributed to physics and engineers ability to understand that physics. There is a lot going on when people press on the brake pedal in their car. The most basic principle of brake pads is in fact friction. This friction is the thing that transfers the energy of the car moving forward to heat energy. Brakes also use pressure as a…

Stress is a very complex topic. To my understanding it is an emotion felt not only mentally but physically as well. A large straining that you endure from being under immense pressure, at times you feel there is no way out. It can come from the negativity of your peers, and almost always from your very own self-doubt. Stress to me as a student and as a worker are very separate functions. From my student side I worry about not doing well on not only one but a series of demanding tasks from all of…

Ego’s Blinders: Perspective as a Projection of Success In his article “Keywords”, Raymond Williams describes three meanings of the word ‘nature’: “(i) the essential quality and character of something, (ii) the inherent force which directs either the world or human beings or both; (iii) the material world itself, taken as including or not including human beings” (219). Different perspectives on nature and its value are present in all forms of literature. William Shakespeare’s play As You Like It…

The History of the Development of the Four Fundamental Forces Nature has a total of four fundamental forces. The forces include gravitational, electromagnetic, strong nuclear and weak nuclear force. Gravitational force is the force of attraction between all masses. Every object in this universe is pulling upon other objects. Many scientists came up with logics to explain the science behind gravitational forces. The first one to try was Aristotle in around 330 BC. Aristotle believed Earth and…

Explain how Newton 's first law applies to air bags, seat belts, and headrests. Newton’s first law applies to air bags, seat belts, and headrests in terms of keeping your body at rest while you are driving, which in turn will keep you safe. When you crash your car, the motion of your body in the car matches the motion of the century itself, so when it crashes, your body has the tendency to stay in motion. So, with the headrest, seatbelt, and airbag, they are all designed to slow down the forward…

Newton's second law F=ma states the more mass the more force is required to accelerate an object, but here force is not involve only radius and speed. Therefore mass does not affect the acceleration. This is proven by the data “table 2” since acceleration remained the same for all ten difference masses. Next, changing the radius will…

When lining up your shot, try moving your body weight a little more forward than usual. This will help you to hit down on the ball and keep it out of the air. Don’t Force It: As much as you may wish you could, you cannot control the wind. However, you can control the level of risk that you take with each shot. On a par five, for example, you do not have to try to reach the green in two strokes. On a windy day…

PE Coursework Strengths The sport I have chosen is football. One of my main strengths (components of fitness) in football is my speed. The definition of speed is the ability to move quickly across the ground or moving limbs rapidly to grab or throw. In football, you use your speed for e.g; When you’re attacking and you are dribbling past a defender, you can use bursts of speed to blow past him. This means I get closer to the goal and have a better chance of scoring for me and my team. Also,…

oppose force acts against to its motion is called friction force as shown in fig.1.7. The friction is not a property of material, but it is a system response. The ratio of…

discuss the effect of compressive force, tensile force, shear force, bending force on structural member 1) Timber: Compressive force on timber: - The effect of a compressive force on a timber is a change in structure of a material and to carry a load within its limits. Tensile force on timber: - The tensile force is the pulling force exerted on both the ends of a timber. Both the ends of a timber will undergo tension. Shear force on timber: - The shear force is the force which pushing the one…
