Physics Moment of a force: Moment of a force = force x perpendicular distance of the line if action if the force from fulcrum Law of moments: When a body is in equilibrium the sum of the clockwise moments about any point equals the sum of the anticlockwise moments about the same point. Centre of mass: Centre of mass is the point where whole mass of the body assumes to be concentrated. II. If the vertical line through the centre of mass is outside the base it will be a topples but if it’s passed

UNSOLVED MYSTERIES Unsolved Mysteries - Beyond the standard model The Standard Model is nowhere near perfect. It may explain the six quarks‚ leptons‚ and four forces‚ but it is not complete. There are still questions about antimatter‚ dark matter‚ and the inability for the Standard Model to predict particle mass. There is no guarantee that quarks and leptons are actually fundamental. Lastly‚ scientists still don’t understand gravity’s role. Unsolved Mysteries - The standard model as a theory

Physics ABC Book By- Alexis Vellis 2nd period 10/14/12 Atom The basic building blocks of all matter. Atoms are microscopic‚ meaning you cannot see them without a microscope. Black Hole A Black hole is a place in space where the gravity is so strong that nothing can escape it pull. Cyclotron A type of particle accelerator that was created first in the 1930’s. It was made of two Dshaped cavities in a constant magnetic field. Dark Matter A form of matter that is not like ordinary

Soccer Physics In this paper‚ I will explain the physics concepts of air pressure‚conservation of energy‚ gravity‚Inertia‚ and impulse momentum as they relate to the sport of soccer. I will also explain how knowing these laws can benefit how you play. The first physics concept I will talk about is air pressure. When you kick a soccer ball more energy transfers to a highly pressurized ball‚ as for a non inflated ball‚ the motion of the kick goes into the ball instead of moving the ball

Although some physical issues appear to be difficult to understand‚ explain James Kakalios achieved from conduction and convection to modern physics. It is much easier to learn when it comes to something you love‚ that’s why the lessons presented in the book seemed understandable. One of the first issues of the second half of the work are phase transitions. Reading the title of the section I figured it would be a very complicated and it would take me a long time to know the subject. I realized‚ the

The movie Titanic is close to the real accident happened on April 14th‚ 1912 and there’s a lot of physics involved in the movie. We have to admit that James Cameron really spent plenty of time on the causation of the accident. ① physics side note: Pressure (√) At the beginning of the movie‚ there is a group of people who want to find the invaluable “Heart of the Ocean”.

Abstract :The purpose of the experiment is to explore elastic and inelastic collisions in order to study the conservation of momentum and energy. The guided track‚ carts‚ photogates ‚ 250 g weight and picket fences were the primary components used in the procedural part of the experiment. Each experiment involved the use of the photogates and picket fences to measure the initial and final velocities of both carts when they collide. The data was collected and translated to a graphical model for further
