stay on the tracks, and brakes. Roller coasters are actually controlled by physics. Different types of energy and forces are necessary from the ride to move without extra aid. These are kinetic and potential energy, inertia, gravity, air resistance, centripetal force, and friction. Potential energy is stored energy, while kinetic energy is energy of movement. Acceleration is an increase in speed. Gravity is the force that pulls objects to the center of the Earth. Inertia is an object’s resistance
unless acted on by an unbalanced force. A prime example of this is depicted in aircraft engineering; it can be applied to the thrust and drag of the airplane. The second, an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. The way this applies to aircraft engineering is that it can be applied to the acceleration and velocity of the aircraft. The third, Acceleration is produced when a force acts on a mass. The greater the mass
INTRODUCTION WHAT IS QUANTUM? Quantum is the Latin word which means “the smallest possible discrete unit of any physical property”, such as energy or matter. Quantum came into existence in 1900, when the physicist Max Planck used it in a presentation to the German Physical Society. Planck had sought to discover the reason that radiation from a glowing body changes its colour from red to orange and finally to blue when the temperature is raised. He found that by making the assumption that radiation
The branch of physics which deals with mechanics (statics and dynamics) of fluids and the forces on them. Where, fluids include liquids, gases, and plasmas. Fluid mechanics can be divided into two disciplines: Fluid statics: The mechanics of fluids at rest under action of forces. Fluid dynamics: The mechanics of the effect of forces on fluid in motion. 1.2 Fluid Mechanics and society: 1.2.1 Sports:
demonstrated concepts associated with physics. There are a couple of physic concepts displayed including Newton’s law of motion, the law of conservation of energy, friction and air resistance. There were also many difficulties faced during the creation of the mousetrap car and many improvements may have been made. Newton’s first law of motion states that any object at rest will remain at rest, and a moving object will remain at constant velocity unless an unbalanced force acts on it. This is also known
Introduction Nowadays, cars play a very important role in our lives. Although very complex, they are some of the best facilities the human being has created. Cars are powered by engines. There are many types of engines, according to, the number of strokes, the design of the engine, the fuel used, the method of ignition, the arrangement of the cylinder and the air intake process. For example; four stroke engine, two stroke engine, rotary engine, diesel engine, electric engine, single cylinder engine
