Independent Assessment Physics Lab (SL): Cantilever Flexion Cherno Okafor Mr. Ebrahimi SPH4U7 October 21st‚ 2012 Introduction Purpose: The purpose of this Physics Lab is to investigate what factors determine the amount of flexion of the cantilever. Hence‚ the objective is to establish a relationship between the length of a cantilever‚ which may give some insight into the physics of cantilevers. Hypothesis: If one increases the length of a cantilever‚ one would expect there to be an

high temperature but contain very little heat and vice versa (physics 312). When a hot body is mixed with the cold body‚ the hot body cools down and the cold body warms up until the mixture as a whole comes to a common temperature‚ that is‚ in thermal equilibrium. By mixing hot and cold substances and measuring the change in temperature‚ the thermal characteristics of the substance can be determined. The purpose of this experiment is to understand the difference between heat and temperature‚ and

RESISTANCE INTRODUCTION In the society‚ some times street lights glow in day time due to any reason. In mines area people face many difficulties due to absence of light in the nights. In frontier and hilly areas‚ people face many problems due to damaged street lights. For solve above these problems‚ we create a device in which the lights glow in night and in day time‚ they off automatically and don’t glow. Due to use of it‚ we can solve above problems and can also save electricity and men’s power

must be as so that the centripetal force and the force of gravity are equal. (Since velocity is distance divided by time the time needed to decrease for the velocity to increase.) Overall‚ accounting for the minute errors that occurred throughout the procedure‚ the expected results were attained. The tension produced by hanging a mass from a string was measured as being roughly equal to the tension produced from the centripetal acceleration of a stopper attached to the same string. Evaluating

The acceleration at this point in the motion is [pic] downward. (c) Set Up: The time to make one rotation is the period T‚ and the speed v is the distance for one revolution divided by T. Execute: [pic] so [pic] Evaluate: The radial acceleration is constant in magnitude since v is constant and is at every point in the motion directed toward the center of the circular path. The acceleration is perpendicular to [pic] and is nonzero because

experimental result along with its uncertainty allows other people to make judgements about the quality of the experiment‚ and it facilitates meaningful comparisons with other similar values or a theoretical prediction. Without an uncertainty estimate‚ it is impossible to answer the basic scientific question: "Does my result agree with a theoretical prediction or results from other experiments?" This question is fundamental for deciding if a scientific hypothesis is confirmed or refuted. When we make

Physics of a Light Bulb Catherine Bellet Lab Partners: Natalie Russell Alex Harris TA: Chad Lunceford PHY 114 TH @ 2:25pm Abstract: Ohm’s law states‚ via the equation V=I*R‚ that the voltage found across a piece of material is proportional to the current. If the temperature remains constant therefore the resistance is found to remain constant. Stefan-Boltzmann law states that when the temperature if above an average of 1000K‚ then the relationship of voltage and current should be found

PHYSICS PROJECT TO STUDY THE OPTICAL LENS OF A HUMAN EYE Eyes are organs that detect light‚ and convert it to electro-chemical impulses in neurons. The simplest photoreceptors in conscious vision connect light to movement. In higher organisms the eye is a complex optical system which collects light from the surrounding environment; regulates its intensity through a diaphragm; focuses it through an adjustable assembly of lenses to form an image; converts this image into a set of electrical signals;
