Nowadays‚ with the invention of the microwave and with the popularity of fast food restaurants‚ food has become easier to prepare than ever. Do you think microwave ovens and fast food restaurants are beneficial to society? Use specific reasons and examples to support your answer. Most of the people prefer fast foods and foods cooked in microwave oven instead of preparing and cooking foods at home that takes longer. The trend of having food quickly has advantages and disadvantages. I think this

OThe Physics of Airplanes Background: At any given moment‚ roughly 5‚000 airplanes crisscross the skies above the United States alone‚ amounting to an estimated 64 million commercial and private takeoffs every year (source: NATCA). Considering the rest of the world ’s flight activity‚ the grand total is almost incalculable. In order to understand how airplanes fly‚ we must break down the parts of an airplane and understand the physics behind the airplanes most important components: the engine/propeller

Living in a small town / big city There are some differences between life in small town and life in the big city. Firstly‚ the environment in a small town is better than in the big city. In the big city‚ it is noisier than small city where it is usually quiet and peaceful. Secondly‚ big city has a very high number of all kinds of vehicles in the street‚ which often causes severe traffic jam. On the other hand‚ the street in a small town is much less crowded. Thirdly‚ life in a small town is more

Module 2 Honors Extension: The Physics in Swimming Physics is defined as the branch of science concerning the study of matter and energy and the interactions between the two. Physics tries to explain the nature of the world around us‚ how things happen and why. Swimming displays some physical properties‚ such as buoyancy‚ drag resistance and propulsion. We swimmers are at a constant battle to stay afloat‚ while fighting through the water and propelling ourselves forward‚ and we do so using technique

Minela Sljoka Notes on Physics Inertia- tendency of an object to maintain motion. Property of matter. Not newton’s first law. Matter wants to maintain motion- moving objects want to stay in motion if stopped wants to stay stopped. Mass is measure of inertia. Things have mass because they have inertia. Units: kg Symbol m in equation. Inertia is most constantly called rest mass but we call it mass because we are dealing with speeds not going to speed of light. Kinetic Energy- v^2 is proportional

The independent variable is the rise of the ramp‚the dependent variable whether or not the marble will loop the loop. The underlying principle of all roller coasters is the law of conservation of energy. When a roller coaster crests the first big hill‚gravity takes over. Potential energy is sometimes known as positional energy. As the roller coaster falls is has enough kinetic energy to make it through the remainder of the ride. Inertia keeps the object in motion. The other forces bring the roller
