For an object pulled or pushed horizontally‚ the normal force - N - is simply the weight: N = m g (2) where m = mass of the object (kg‚ slugs) g = acceleration of gravity (9.81 m/s2‚ 32 ft/s2) Frictional Coefficients for some Common Materials and Materials Combinations Materials and Material Combinations Static Frictional Coefficient - μs Clean and Dry Surfaces Lubricated and Greasy Surfaces Aluminum Aluminum 1.05 - 1.35 0.3 Aluminum- bronze Steel 0.45 Aluminum Mild Steel 0.61 Brake material

variable represents the length of the string and the dependent variable represents the period of one oscillation. The control variable is the mass of the pendulum. In this lab our goal was to see if we can prove if the acceleration due to gravity is 9.8m/s2. The R2 in this lab is closed to 9.8 m/s2 . The formula that we used in this lab is T=2πLg and then we solved for g=L(T2π)2. HYPOTHESIS: The gravity will be 9.81 m/s2 at sea level due to the acceleration. PROCEDURE: Materials: stopwatch‚ meter

Aim: To find the mass in grams (m) of a paperclip. Apparatus: Procedure: 1. Using a piece of string‚ the external circumference(C) of the small test tube was found and was then used to find A ‚ the cross sectional area of the small test tube A=C24π . 2. The beaker was placed under the test tube after it was clamped on the retort stand to collect excess water. The large test tube was filled with water. After which‚ the small test tube which had a fitted scale was placed inside to float

Introduction. Friction was studied in this lab. The experiments were conducted using a clipboard glued to various surfaces with diffirentiating frictional properties. In order for us to test the varying Static friction or Kinetic friction we used a Newton force gauge‚ some wooden blocks‚ and a metal weight. The actual experiment consisted of two parts. The first part measured the net force‚ or more specific the net force required to overcome the kinetic friction coefficient‚ to move the block across

Science in the Big City: Exploring Career Opportunities in the Natural and Physical Sciences New York City May 13-18‚ 2014 Students in the Natural Sciences at the University of Houston-Downtown are generally accomplished and motivated students with strong interests in science. However‚ students typically have a very limited perception of the science careers available to them outside of medicine. To educate students as to the array of potential careers available in the sciences (not medicine)

April 29‚ 2014 Abstract The objective project was to use our knowledge of physic properties to create a working car that was powered by a mouse trap. I found that the lighter the car was and the more traction the car had‚ the further it travelled. Introduction The purpose of this project was to create a car that is powered by a mouse trap. We were to use our knowledge of physics laws to make the best car we can. I knew from Newton’s Law‚ F=ma‚ that if my car had a lower
