I. Introduction Physics is the natural science that involves the study of matter and its motion through space and time‚ along with related concepts such as energy and force. More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy. Over the last two millennia‚ physics was a part of natural philosophy along with chemistry‚ certain branches

Like many before me one of my most defining moments came from my high school days when I was still attempting to find a balance between getting good grades and maintaining a social life. During that time‚ I was just entering a period where I had dealt with bullying without standing up for myself in school. As a result‚ I entered high school somewhat embittered but also made it intentionally difficult for others to get close to me since many of the people I had once held close to me had turned on

Translational motion Translational motion is the aspect in which a body moves from a specific point to the next. This can be in terms of objects‚ molecules or atoms. This kind of motion normally takes place in a straight line for instance bullet which is fired by a gun. The object in motion does not change by turning on its axis for it travels in a straight line. Any slight change or rotation can cause the object to change direction in general making it not move toward the specified direction.

BALANCING OF ROTATING MACHINES The first thing to be explored to control vibrations is to try to alter the source so that it produces less vibration. This method may not always be feasible. Some examples of the sources of vibration that cannot be altered are earthquake excitation‚ atmospheric turbulence‚ road roughness‚ and engine combustion instability. On the other hand‚ certain sources such as unbalance in rotating or reciprocating machines can be altered to reduce the vibrations. This can

The Magnetic Separator can separate raw materials with different magnetic rigidities. The machine works under the magnetic force and machine force.Magnetic Separators are designed to recover ferromagnetic materials. The separators are available in designs and sizes to provide solutions for all applications. The heart of each separator is the magnetic system with its unique design‚ which has a proven record of high efficiency. Slurry magnetic separator (magnetic the separator) to mine box into the

Prayer In Public School Over the past century‚ prayer has slowly but surely been phased out of public school. It used to be a daily and mandatory event. Of course‚ with anything that is required‚ there are always people who try to refute it. The results of prayer being mandatory are shown today. It has been taken out of the daily routine. Some of the core principles that this country was founded upon have been taken out of the public school system. This was because of the diverse populations that

Chapter 11 Rolling‚ Torque‚ and Angular Momentum In this chapter we will cover the following topics: -Rolling of circular objects and its relationship with friction -Redefinition of torque as a vector to describe rotational problems that are more complicated than the rotation of a rigid body about a fixed axis -Angular momentum of single particles and systems of particles -Newton’s second law for rotational motion -Conservation of angular momentum -Applications of the conservation of angular

My favorite Bazinga moment was during one of my high school soccer games when I nutmegged my opponent on the opposite team. Now a nutmeg in soccer is when a player pass the ball through an opposing players legs and it is one of the most embarrassing things that you can do to your opponent especially when a crowd is present at the game. I won’t reveal the name of the kid or what school we played against because I don’t want to ruin his life. I found it to be extra funny because the kid was talking

For this one‚ you have to do part © first… and don’t forget that ur working with a sphere‚ so u gotta look up the moment of inertia (I) in order to get the correct answer… a) Of the total kinetic energy of the sphere‚ what fraction is translational? U just divide the translational found in part (b) by KEtotal ((1/2)mv2 + (1/2)Iω2) 0.71
