of the motion. We find experimentally that the force of friction is directly proportional to the "normal force." When an object is sitting on a horizontal surface the normal force is just the weight of the object. However‚ if the object is on an incline then it is not equal to the weight but is calculated by N= mg cos θ. The constant of proportionality is called the coefficient of friction‚ µ. When the contacting surfaces are actually sliding one over the other the force of

Since the Grignard reagent can easily react with water‚ all glassware including the 25 ml round bottom flask‚ magnetic stir bar‚ 3 and 5 ml conical vial‚ 50 mL Erlenmeyer flask‚ claisen adapter‚ drying tube and 5 glass pasteur pipets were first added to a 250mL beaker and placed in the oven for 30 minutes. After the completion of the thirty minutes‚ 0.150 g of shiny magnesium turnings and a stir bar was first added to the round bottom flask and the claisen adapter along with the drying tube packed

Investigation 2.5: Acceleration Due to Gravity of Different Masses SPH 4CI-01 Al Einstein‚ James Maxwell‚ Isaac Newton‚ James Watt Mrs. Joldwcks Due Date: July 19‚ 2008 Cut-Off Date: July 21‚ 2008 Purpose: To determine if the mass of a falling object affects its acceleration rate. Hypothesis: The greater the mass of an object‚ the greater its rate of acceleration because more massive objects have more gravitational force exerted on them by the Earth. Materials:

Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

the pendulum‚ and g is the constant of the acceleration from gravity. To calculate an accurate value for g‚ I used 2 values for L on Moon and Jupiter of 2.5m and 1.00m. From there I used the simulation to calculate T and I plugged that into the equation to find g. The average value of g on the moon is 1.606m/s^2. Also‚ the average value of g on Jupiter is 18.913m/s^2. The results are listed in the table below. Location Length(m) Period(s) Acceleration of Gravity(m/s^2) Moon 2.50m 9.022s

that all data collected and measured in the lab are accurate and reliable as well. The process of testing an instrument’s accuracy is known as calibration. The purpose of this lab was to calibrate a variety of equipment frequently utilized in the Exercise Physiology lab and to become familiar with the operation of the calibrated equipment (Lab manual). The equipment calibrated in the exercise physiology lab was the speed of the Parvo treadmill‚ the incline of the Cosmed treadmill‚ the resistance of

conducted on 13th August 2008 in Machines Dynamics Laboratory. The experiment was conducted in groups of four‚ and was supervised by lecturer Mr. Mohd Azahari Johan. Conducting this experiment is for fulfilling the requirements of Applied Mechanics Lab (MEC 424). A pendulum is defined as body so suspended from a fixed point as to swing freely to and from by the alternate action of gravity and momentum. It is used to regulate the movements of clockwork and other machinery. Therefore‚ a compound

The lesson is divided into 3 labs that can be completed in any order. After labs have been completed‚ facilitate a class discussion where students summarize and compare findings and relate how their findings support (or refute) Newton’s Laws of Motion LAB 1: How fast can it go? Put one car at the top of the ramp and let it roll down. Use a stopwatch to record the time the car rolled. Use this information to calculate the acceleration of the car. Measure the distance the car rolled using the

subtopics of kinematics and dynamics. Kinematics is concerned with the aspects of motion that exclude the forces that cause motion. In a manner of speaking‚ kinematics is focussed on the development of definitions: position‚ displacement‚ velocity‚ acceleration and on the relationships that exist between them. Dynamics widens the study of motion to include the concepts of force and energy. Definitions Position Kinematics begins with the idea of position. Suppose that we photograph an object moving

The purpose of this lab report is to differentiate between of Newton’s Third Law and Newton’s Second Law. Newton’s Third Law states that all forces come in pairs and that the two forces in a pair act on different objects and are equal in strength and opposite in direction. Newton’s Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated. Using calculation equations for acceleration‚ force‚ and percent
