displacement. Applying a mass to the end of the spring stretches it‚ changing the length from its original equilibrium position of rest‚ to a new (lower) equilibrium position. At this position‚ the vertical restoring force of the spring balances the weight and the downward pull of gravity is balanced by the upward pull of the spring. In simulation‚ by adding any of the mass to the spring‚ equilibrium position is changed‚ the more the mass the farther the spring stretches. 4. Explain the effect of gravity on

philosophy from the Modern Era when society was industrial‚ England’s culture untolerating‚ the mass media conservative and pro-establishment. Role in society was extremely important; it was traditional and genders specific. Functionalism provided a static view of society. It was rooted in the work of Emile Durkheim‚ a French Sociologist and during the later stages‚ Talcott Parsons. Although functionalism was not a dominant theoretical perspective in sociology until the 1940s and 1950s‚ it first emerged

Objectives (1) To measure the velocity and acceleration of a trolley as it descends on inclined track and is stopped by a nonlinear elastic arrester system. (2) To compare the measured acceleration‚ velocity and displacement with theoretical

Research Question How does spacing between dominoes affect the average velocity of the dominoes? Increasing space between each domino will decrease its velocity‚ decreasing the space will increase its velocity. Force at which it hits next dominoes is increased it will take longer for it hit‚ acceleration is constant‚ the longer it has to travel‚ the longer it will take to hit. According to Newton’s first law every object in a state of uniform motion tends to remain in that state of motion

you are right - I just don’t know! 1. Tension‚ Weight‚ Friction: You are taking advantage of an early snow to go sledding. After a long afternoon of going up and down hills with your sled‚ you decide it is time to go home. You are thankful that you can pull your sled without climbing any more hills. As you are walking home‚ dragging the sled behind you by a rope fastened to the front of the sled‚ you wonder what the coefficient of friction of the snow on the sled is. You estimate that you are

The Limbic System Most reptiles and lower order organisms only have the “old brain”‚ the evolutionarily oldest part of the brain responsible for vital tasks such as breathing and sleeping‚ whereas higher order organisms have a limbic system. The old brain is comprised of the pons‚ the medulla oblongata‚ the brain stem‚ the thalamus‚ the cerebellum‚ and the reticular formation. The reticular formation is a network inside of the brain stem‚ part of the “old brain” that is essential for arousal (sleeping

Physics Formulas: Mechanics Mechanics is the oldest branch of physics. Mechanics deals with all kinds and complexities of motion. It includes various techniques‚ which can simplify the solution of a mechanical problem. Here are some of the often required physics formulas falling in mechanics domain. Motion in One Dimension The physics formulas for motion in one dimension (Also called Kinematical equations of motion) are as follows. (Here ’u’ is initial velocity‚ ’v’ is final velocity‚ ’a’ is

Kinetic Friction Experiment #13 Joe Solution E01234567 Partner- Jane Answers PHY 221 Lab Instructor- Nathaniel Franklin Wednesday‚ 11 AM-1 PM Lecture Instructor – Dr. Jacobs Abstract The purpose of this experiment was to examine kinetic friction and what factors affect it. We pulled a wood block across a surface to determine whether the surface area of the block or the type of surface affects friction. The surface area did not appear to affect friction‚ since there was a small percent difference
