Question One The equation derived in the lab manual is hereby recalled as; a=(F_M-F_m)/(M+m) =(Mg-mg)/(M+m) =[(M-m)/(M+m)]g Therefore to determine whether this equation makes sense, we will equate each of the masses to zero. Experimentally, when one mass is equated to zero, say, by removing all the pennies in one mass,...

Isaac Newton first published his Universal Law of Gravity in the journal, Philosophiæ Naturalis Principia Mathematica, in July of 1687. The story goes that one day, Newton was sitting underneath an apple tree when an apple suddenly fell to the ground. He considered the problem with this, wanting to understand...

Theory The primary aim of this lab is to determine the correlation that exists between centripetal force, mass, and velocity of an object that is experiencing centripetal acceleration. The object will always be changing direction while maintaining its movement in its circular path. Centripetal force is the term used to...

Question 1 According to Newton’s First law, a body will remain in a state of rest or uniform motion, unless it is acted upon by an external force (“S-Cool, the revision website). In this case, the mass is in an uniform motion which means that there is no acceleration. Since...

X-ray are classified and outlined as an electromagnetic type of waves. They transmit high energy hence can pass through molecular substance. As a result, the energy makes them critical especially when it comes to medical applicability. More importantly, the waves find high usability in industrial processes especially in packaging of...

Essence: The motion of a body can be determined by comparing it either to a fixed reference or moving reference point. In this specific experiment, the motion of the body is measured relative to a fixed reference point which contains a sensor. The sensor sends pulses to cardboard reflector which...

Theory Energy forms one of the most basic concepts in the field of science. It is the ability with which a given system or performs its work. Energy has been subdivided into various forms such as mechanical and electrical energy. Mechanical energy can further be grouped into two distinct categories...

Adrian Bejan was invited to a TEDx MidAthlantic to talk about his concept regarding the physics that rules nature and society. In numerous examples the speaker outlines the various effects explained with physics and its basic principles to be used in predicting the development of some points under scrutiny. He...

One of the article "Dehydration Melting At The Top Of The Lower Mantle." Suggests evidence of large water reservoirs trapped inside the transition layer of the earth sub surface. The study by Brandon Schmandt argues that there are the huge water reservoirs that could be the cause of dehydration melting...

From the analysis of this lab, we can conclude that the impulse-momentum theory is correct. One way to compare the values of the launch portion and the landing portion was finding the percentage difference multiplied by 100%. Percentage wise the error was 1.5%. The values were close undoubtedly proving the...

Understanding how alternative energy such as wind, coal, solar and nuclear plant are generated and transmitted into our homes is usually a concern of most people. To begin with, it is important to understand that the generation of any form of alternative power begins from the power plant where water...
