• ## Simple Pendulum Experiment

Experiment-1 Simple pendulum: Aim: The main aim of this simple pendulum experiment is to investigate the relationship between the time period of a simple pendulum (oscillation) and the effective length (total length) of the simple pendulum. The three variables in Experiment-1 Simple pendulum: Independent variable: The independent variable in this experiment is the length of the string of the pendulum that could be changed. Dependent variable: The dependent variable is the time period for one…

• ## Advantages Of Long Jump

Long Jump Procedures: The participant has to stand behind the line and has to jump off of both feet and attempt to jump as far as possible while landing on both feet. The participant gets three chances to jump as far as they can, then they record their data. Advantages: This test does not take very long to do and it does not require a lot of equipment. Disadvantages: It takes some form to know how to do this properly so some participants may have an advantage over others. Validity: it is a good…

• ## Lab Report: Uniform Motion Of The Ping-Pong Ball

necessarily mean that there is no force acting on it. Motion can also be studied by using momentum (f=((mv-mu))/t ) as a quantity. Uniform motion is when the displacement of an object is constant with respect to time. Note that there has to be some displacement for it…

• ## Stepper Motor Reflection

Motor & Gearbox The mirrors are required to rotate specific angles. To be able to achieve specific angles we need a stepper motor. The stepper motor is known to divide one revolution into equal steps which is our main requirements for the rotation of the mirrors. Figure ‎2-13: The Stepper Motor The following table shows the stepper motor specifications: Table ‎2-1: Stepper Motor Specifications Current 4.2 A Angle 1.8° Torque 8.34 N.m The desired torque calculated to withstand the mirror…

• ## Concepts Of Map Scale

Question 2: Map scale is the ratio of the straight line distance between any two points on a map to the straight line distance between the same two points on the earth’s surface. Now when looking at map scale there a few concepts for instance, ratio (representational fraction) scale is a concept of map scale. Ratio scale is always neutral in the scale measurement used on the map. So when looking at a map scale of 1:50 000 it means that 1 unit of measurement on the map is equal to 50 000 of the…

• ## Benefits Of Relax And Make Yourself In Shava Asana

 Make yourself in Shava Asana. Now raise whole body towards sky in such a way that that only shoulder and head is on the ground .  While inverting yourself balance your raised body with the help of your hands holding the back with bent elbows on the the floor ,making broad base for supporting upright straight body.  Try to keep raised part of body straight as shown in picture.  During this maintain normal breathing and stay in the posture for a while.  Now slowly slowly bring down raised…

• ## And Potength: The Strength Of Anisotropy

4.1 Strength of Anisotropy “The strength of anisotropy is calculated by the “kern and Richter” formula which gives the magnitude anisotropy k= (Vmax –V min)/Vmean, where Vmax and Vmin are maximum and minimum velocity. For P wave in the olivine crystal Vmax and Vmax are 9.89 and 7.72km/s respectively, so strength of anisotropy is 25%. For S wave k= 22% for Vmax and Vmin are 5.53 and 4.42 km/s respectively” [Seth stein 2003]. This anisotropy is the intrinsic anisotropy of the material defined as…

• ## Friction And Force Of Static Friction

Problem: Is there a relationship between the mass of an object and the force of static friction and force of kinetic friction of that object? If so, what type of relationship is there? Background: Friction is a type of force that is created when two surfaces move across one another. Static friction is friction between two or more solid objects that are not moving relative to one another. Kinetic friction is the amount of friction between two objects that are moving relative to each other.…

• ## Why Langmuir Isotherm?

(a) Langmuir isotherm model Langmuir isotherm is based on the following assumptions: (a) each surface site can be singly occupied, (b) there are no lateral interactions between adsorbed species, (c) the enthalpy of adsorption is independent of surface coverage and (d) energy of adsorption is constant. The Langmuir isotherm is 2.5…

• ## Spring Fall Lab Report

Y-Component x- X-Component Mathematical Model Basic Equations: Force Equation (used to find the force of any given object): F=ma F-Net Force, m-mass, a-acceleration Summation of Forces on X-Axis: 〖ΣF〗^x=F^(G,x)-F^Sp 〖ΣF〗^x is the sum of the forces on the x-axis, denoted by the superscript x, and the x-axis follows the Free-Body Diagram above. F^(G,x) is the x-component of the Force of Gravity by the Earth on the cart. F^Sp is the Force of Spring on the cart. Hooke’s Law for Springs:…
