constant. If a ball is attached to the end of string and swung at a constant speed (i.e. only the direction of the velocity is changing not the magnitude) then there must still be an acceleration. The acceleration is directed towards the center of the motion. This acceleration is call centripetal acceleration! 2.6.2 State the expression for centripetal acceleration. The acceleration of any object moving in a circle at a constant speed is given by the equation: (1) a⃗ =v2r It is important to note

You are now entering the human heart The short story “You are now entering the human heart”‚ written by Janet Frame is a short story focused on the fear of something strange‚ to overstep boundaries and to be under pressure. I think the feeling is something‚ that we all know how feels. My definition on fear would be something about‚ that it is an emotional response to a threat. We all know the feeling‚ when you sweat like you have accomplished a marathon race‚ the adrenaline pumps inside your body

law of motion: For every action‚ there is an equal and opposite reaction. How this applies to our bottle rockets that we constructed‚ is that when we release‚ the water and air pressure comes out of the bottom. That pushes against the ground‚ the equal and opposite reaction is the earth pushing back up. Whatever object has less mass moves. In this case‚ the rocket has less mass than what it is pushing against; the earth. When we created our rockets‚ we had to keep all 3 laws of motion in mind

Newton’s second law of motion (Car vs Suv) According to newton’s second law of motion‚ Acceleration is produced when a force acts on a mass. The greater the mass is‚ the grater the acceleration is needed to move forward. This law basically states that a force applied to the objects changes its velocity overtime in the direction of the force that is applied‚ the acceleration is directly proportional to the force‚ as an example‚ if pushing on an object‚ causing it to accelerate‚ and then you push

Charlie Shinske During the Progressive Era‚ pressure from labor‚ suffrage‚ and conservation movements profoundly changed the course of American history. Many of the reformers’ ideas clashed with the male-dominated‚ capitalist economic structure present at the turn of the century. Some of the intended reforms opposed the current system‚ but the level of social unrest necessitated change. Businessmen and activists alike initiated the reforms during the Progressive Era. Government‚ due to the intention of

The Progressive Movement (1900-1920) was basically a reform movement. The movement drew its ideals and inspiration from the writings of Thomas Jefferson and reform groups that had attracted some attention in the 19th Century. The progressives were successful in part because they were able to rally the better part of a generation to their ideas about reform. While not all progressives supported all progressive reforms‚ the basic objectives of the movement included the following: Destruction of the

Schubert’s Romantic Era During the period of 1800- 1850‚ many well- known composers and musicians have been thought to be the most prominent persons of their time. Franz Schubert and his work came to be known following his death. This paper will explain how Franz Schubert was the most influential musician in transit from the Classical Era to the Romantic Era. Schubert’s development of Lieder and cyclic form makes him the most influential musician of the Romantic Era. Franz Peter Schubert was born
