ROTATIONAL MOTION CENTRE OF MASS AND ROTATIONAL MOTION INTRODUCTION- For describing the motion of rigid bodies‚ we shall introduce the key concept of ‘centre of mass’. This concept enables us to understand how we can apply justifiably the Newton’s laws of motion‚ in essentially the same form to objects of large size including even the astronomical objects like the planets and the stars. KINDS OF MOTION OF A RIGID BODY- A rigid body may have three kinds of motion- (1) Pure Translation Motion- in such

2. LINEAR MOTION In this experiment you will study the motion of an object in one dimension from a number of points of view. You will demonstrate how the variables of motion are related by differentiation and integration and investigate the relationship between potential and kinetic energy. Theory Why Study Motion? Motion is everywhere in the universe. Only at a temperature of absolute zero is the motion in any body truly absent. If motion exists then so also does energy. To the delight of

his early life experiences and with the knowledge left by his predecessors‚ Sir Isaac Newton was able to develop calculus‚ natural forces‚ and optics. From birth to early childhood‚ Isaac Newton overcame many personal‚ social‚ and mental hardships. It is through these experiences that helped create the person society knows him as in this day and age. The beginning of these obstacles started at birth for Newton. Isaac was born premature on Christmas Day 1642‚ in the manor house of Woolsthorpe‚ 7 miles

Third Age – The Golden Years of Adulthood By Stephen F. Barnes‚ Ph.D. San Diego State University The Third Age is now considered by many to be the “golden years” of adulthood. It is generally defined as the span of time between retirement and the beginning of age-imposed physical‚ emotional‚ and cognitive limitations‚ and today would roughly fall between the ages of 65 and 80+. This is a period of adulthood when typically there are fewer responsibilities (e.g.‚ career and family-rearing) than before

The Nazi rise to power brought an end to the Weimar Republic‚ a parliamentary democracy established in Germany after World War I. Following the appointment of Adolf Hitler as chancellor on January 30‚ 1933‚ the Nazi state (also referred to as the Third Reich) quickly became a regime in which Germans enjoyed no guaranteed basic rights. After a suspicious fire in the Reichstag (the German Parliament)‚ on February 28‚ 1933‚ the government issued a decree which suspended constitutional civil rights and

Lab 1‚ problem 3: Motion Down an Incline Shaoren Yuan October 5‚ 2013 Physics 1301W‚ professor: Dr. Zudov‚ TA: David Abstract The processes of a cart rolling up and returning back along a track were recorded‚ and the processes (motion of the cart.) were described as equations. Also‚ we calculated the accelerations of every stage (aup‚ adown and ahighest). Then the relationship among aup‚ adown and ahighest was concluded. Finally‚ the acceleration was measured and was proved from data. Introduction

(a) Positively accelerated (c) Uniform accelerated (b) Negative accelerated (d) None of the above [1] 2. What does slope of position time graph give? (a) speed (b) acceleration (c) uniform speed [1] (d) Both (a) and (c) depending upon the type of graph. 3. When a body moves uniformly along the circle‚ then:(a) its velocity changes but speed remains the same (b) its

Third Place Third places‚ the world is full of them‚ but how do we know what place is a third place and what place is simply just a place? When you walk into wherever it might be that you go to relax or just get away from work‚ home or school‚ what things in that place make you want to be there? Why have you chosen this place over anywhere else? Everyone has a third place but what exactly is a third place‚ where it is located‚ and what it is made up of to make it an actual third place?

has relevance and meaning in the world today. Many people know the term describes the segregation laws that took place in the 1900’s‚ however that much is not the entire story. The term Jim Crow has roots in the deep south‚ and became so popular it was later used as a nickname to describe laws that dehumanized African Americans and striped them of their rights. “Jim Crow” has its roots in the 1830’s when a white minstrel performer‚ Thomas “Daddy” Rice‚ darkened his face with burnt cork and danced

The third-wave feminists are critical to the first and second waves because it ties all of the women’s movements previous accomplishments to all women‚ regardless of race‚ color‚ sexual orientation‚ and class. Without the third-wave feminists only white women would have the luxury of being able to vote‚ being provided equal employment opportunity‚ being heard when faced with sexual harassment and marital rape‚ and being able to broadcast the discrimination of gender.
