Jean Jacques Rousseau was a Swiss born philosopher. His father was an educated watchmaker. His mother died at childbirth and his father was exiled from Geneva. He had a hard time living with his mother's family. At the age of 16, he fled Geneva and went to France. Paris was culturally very different from Geneva. He suffered from deep isolation and his life was very unstable. He was involved in many strange affairs with women. However, he met a woman named Mme de Warens who was 10 years older…

Sir Isaac Newton was an English mathematician and physicist who lived from 1643 to 1727. Newton grew up with his grandmother, whereas his father passed away shortly before he was born and his mother remarried a man he did not approve of. Newton attended Trinity College in Cambridge and worked as a servant at the university until he was awarded a scholarship because he could not afford the tuition fees. In 1666, the university was temporarily closed due to an extremely contagious, mortal disease…

Elements of Orbital Analysis We first derive a general solution of a two-body problem subject to the universal gravitational attraction (Newton’s Law of Universal Gravitation), and then consider special cases of interest for our purpose. 1.4.1. Equation of Motion under Newton’s Law of Gravitation Using the coordinates shown in Figure 1.2, Newton’s Law of Gravitation implies that the two bodies of masses M and m, and the radius vectors r ⃗_M and r ⃗_m , respectively, would exert the…

OBJECTIVE: The pump is made of pendulum, two-leg lever and cylinder with the piston which pumps the water. Oscillation of the pendulum is maintained by periodical action of the human arm. Oscillation period of the pendulum is twice bigger than the period of the lever oscillation. Piston of the pump has reverse effect on the lever and damps its oscillation. Damping of the lever motion causes damping of the pendulum, but the work of the force damping the pendulum is less than the work of the…

Evie McCormack Mr. Acland B Block Physics Lab: Speed of Sound Essential Question Asked: How does the speed of sound differ between metals and gases? Background Information: The speed of sound is gauged by distance over time (distance/time). Certain aspects that can change or affect the speed of sound would include the density of the item through which the sound is traveling. Continuing on with that concept, when sound is…

Proving Newton’s Second Law of Motion Aim: Prove that a (acceleration) is proportional to the net force and inversely proportional to the mass. Background Theory: Sir Isaac Newton presented his three laws of motion in the Principia Mathematica Philosophiae Naturalis in 1687. The second law, ΣF = ma, states that changes in force will cause an object to accelearate and with this equation, one can figure out how much. It can be rewritten into a = ΣF / m, and thus, it can be seen that acceleration…

Dynamic Traction Control (DTC) is a sub-function of the Dynamic Stability Control (DSC) system that can be turned on and off. DTC has two major roles: to regulate traction and to enable sports-style driving while providing active stability control. When the drive wheels start losing traction the DSC automatically begins stabilisation measures. The Dynamic Stability Control system curbs the engine output and stops slip on the wheels. In exceptional situations, however, a small amount of wheel…

As we know most of the things we humans learn are by mainly active experimentation or passive observation. Imagination is also one way of learning. For example in physics the first structure of atom was first imagine by a scientist but then that keep on changing . What is active experimentation ? it is when you yourself do some thing new ,which is new to you. that is basically active experimentation. what is passive observation ? passive observation is when you see or observe something happening…
