Lab {4} Free Fall Motion Abstract Within this laboratory students used a Macintosh computer‚ scientificwork interface‚ and photogate to measure the acceleration of gravity‚ g‚ in a free-fall experiment. Using a “picket fence” dropped through a photo gate with disregard for air resistance; students calculated the results from the charted data and compared it with the accepted value of 9.8 m/s2 discussing any variations and their

Liberty is the freedom from certain restrictions that are forced on the lives of people in society. But in America‚ liberty is more than just a definition. Liberty is an icon‚ a way of living and a motivation. In fact‚ many of the structures or statues in America have liberty inscribed on them or have the word liberty in the name. For example‚ the Liberty Bell. At a glance‚ the Liberty Bell seems like a regular old bell with a crack down the side. In reality‚ the Liberty Bell is a model of freedom

Traditionally protein is understood to assist in the development of muscle in athletic people‚ but it actually functions as structural support‚ cell adhesion‚ transport for molecules‚ and cellular communication. Through dehydration synthesis‚ the release of a water molecule from the joining of two amino acid groups‚ a peptide bond forms. For the experiment performed in lab‚ amino acids and peptide bonds found in protein were investigated in different food substances‚ it

04/04/2012 Simple Harmonic Motion Lab Introduction: In this two part lab we sought out to demonstrate simple harmonic motion by observing the behavior of a spring. For the first part we needed to observe the motion or oscillation of a spring in order to find k‚ the spring constant; which is commonly described as how stiff the spring is. Using the equation Fs=-kx or‚ Fs=mg=kx; where Fs is the force of the spring‚ mg represents mass times gravity‚ and kx is the spring constant times the distance‚ we

The statue of Prince William the Silent with his dog at his side is located at Voorhees Mall‚ on the College Avenue Campus‚ and is near Van Dyke Hall‚ and Milledoler Hall. The statue is not only a symbol of Dutch independence‚ but also represents the Dutch roots of Rutgers University. In connection to America‚ the Netherlands has become a very

Atoms‚ Molecules and Elements Melissa DuBois Chem 110 September 16‚ 2013 Earl Steven Gurley Atoms‚ Molecules and Elements Atoms are the smallest unit of matter and a group of atoms can form chemical bonds in order to form a molecule. Molecules are groups of two or more atoms that have bound together and are the makings of matter. Elements are a substance that has only one type of atom that make up that element. First we can learn about how halogens and alkali metals are extremely reactive‚ where

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

or concomitantly‚ productive cell infection may be controlled at the membrane level‚ requiring the interaction of a specific cellular receptor with the virus envelope‚ as demonstrated recently for Epstein–Barr virus (EBV)1. Therefore‚ we have investigated whether the T4 molecule itself is related to the receptor for LAV. We report here that preincubation of T4+ lymphocytes with three individual monoclonal antibodies directed at the T4 glycoprotein blocked cell infection by LAV. This blocking effect

that means the object is back where it started. Particle A therefore is back at the origin‚ whereas Particle B has only moved in a positive direction. Hence‚ Particle B is not at the origin‚ and is further away from the origin than Particle A. 3. Which particle moves with constant non-zero acceleration?

Error Analysis: Force constant in springs Maria Loraine Menorca National Institute of Physics‚ University of the Philippines Diliman‚ Quezon City lorainemnrc@gmail.com Abstract This experiment aims to fully understand the analysis of possible errors in the measurement of the force constants in different spring systems. Springs can be utilized to store and release energy. According to Hooke’s Law‚ the response of a spring to external forces is characterized by the equation F = -kΔx. In this experiment
