Lab 3: Newton’s Second Law: The Atwood Machine Introduction: In the study of physics a lot of the basics were put in place by Isaac Newton. Out of the 3 laws of motion he had declared the second law states that force equals mass times acceleration (F=ma). The Atwood machine is a machine that has a pulley in the air and a string running through the pulley‚ some kind of mass is suspended by each end of the string. When the suspended masses are unequal‚ the system will accelerate towards the direction

NEWTON’S SECOND LAW OF MOTION Abstract This study’s objectives are first to verify the direct proportionality of acceleration and net force if the mass of the body is constant and then to verify the inverse proportionality of acceleration and mass if the net force is constant. With the use of‚ mainly‚ the dynamics cart and the weight hanger‚ certain variables such as the mass on the cart and the mass on the hanger which is the net force were manipulated‚ controlled or changed in order to illustrate

other end‚ and then back to the initial position. [1] The equation to calculate period is‚ T = 2πLg Where‚ T = Period of the motion‚ measured in s. L = Length of the pendulum‚ measured in cm. g = Acceleration due to gravity‚ measured in m/s2. The slope of the line in the graph of T² against L can be used to determine the gravity of the pendulum motion. It is because‚ y = mx m = T² L= 4π²g m = Slope of the line in the graph T²/L. Therefore‚ to find the gravity of the pendulum

1.1.1 Defining management The study guide tries to answer the question by quoting a number of definitions. The discussion clearly gives a basic agreement of how management and social work management should be defined. According to Koontz and Weihrich (1998:4)‚ states management: Is individuals‚ forming a group to work with each other to accomplish efficient selected aims by designing‚ and maintaining an environment.

A recent article discussed how tow truck drivers are especially busy when the roads are icy or after it has snowed. While a greater number of accidents are expected when the weather is bad‚ there are several things you can do to make things easier for tow truck drivers in our area. When the roads are icy or when there is snow on the road‚ decrease your speed appropriately. It is important to be aware of black ice. Although you cannot see it‚ you will need to slow down. Otherwise‚ you might slide
