Universal Law of Gravitation in 1687. His law of gravity describes the force amongst every object that contains mass. Newton devised his idea of the law of gravity when he observed an apple fall from a tree. This then lead him speculating about whether the same force that was upheld by the apple was also maintained by the moon. Sir Isaac Newton then reached to the discovery that both the apple and the moon were motivated by the force of gravity. His law of gravity states that ‘every object in the universe

Introduction: This lab is an experiment in terminal velocity‚ the speed an object cannot surpass due to frictional forces. To begin‚ it is important to note that the objects in this lab are not in a free-fall scenario. A free-fall scenario is a situation where an object is dropped in a frictionless environment‚ and the only force that is acting upon it is the force of gravity. In a free fall environment‚ terminal velocity would not occur‚ because no frictional forces would act on the object to

February 25‚ 2013 Lab: Equilibrium of Forces Purpose/Objective: The objective of this lab was to test the first condition of equilibrium for a set of concurrent coplanar forces‚ prove Lami’s Theorem‚ and to determine an unknown mass using rules of equilibrium. Procedure: In the lab‚ we wanted to find at what angles three separate weights would create a net zero force on a force table so that the ring holding the weights was exactly centered in the middle

refraction of light lab used common materials to examine the process of the refraction of light. The title of this lab is exactly what occurs throughout the four different experiments. All four parts of this lab use prior knowledge to observe the complex concept of refraction. Refraction is the bending of a light when it enters a medium where the speed of light is different. When light enters through the glass and water the speed of light becomes decreased. This is due to the density of water being higher

Kharishma Patel BIO 3422-E Urine Analysis Lab Objective The objective of this experiment shall be to examine the effects of different types of fluids on the renal system including rate of urine production‚ pH‚ and specific gravity. Hypothesis The group drinking water will have the highest rate of urine production. The group that drinks water only when thirsty will have the lowest rate of urine production. The specific gravity of urine for all treatment groups will be around 1.000. The pH for

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With
