Kinetic Friction Experiment #13 Joe Solution E01234567 Partner- Jane Answers PHY 221 Lab Instructor- Nathaniel Franklin Wednesday‚ 11 AM-1 PM Lecture Instructor – Dr. Jacobs Abstract The purpose of this experiment was to examine kinetic friction and what factors affect it. We pulled a wood block across a surface to determine whether the surface area of the block or the type of surface affects friction. The surface area did not appear to affect friction‚ since there was a small percent difference

Experiment 7: Relative Density Laboratory Report Marella Dela Cruz‚ Janrho Dellosa‚ Arran Enriquez‚ Alyssa Estrella‚ Zacharie Fuentes Department of Math and Physics College of Science‚ University of Santo Tomas España‚ Manila Philippines Abstract The experiment was conducted to show the different methods on how to determine an object’s composition through its density and to determine an object’s density by displacement method and the Archimedes Principle. Results show that. The materials

The Physics 500 Introduction: The purpose of this lab is to show how to calculate the average speed and acceleration in six different races. In order to find average speed you will need to use the formula s=d/t (s= speed‚ d=distance‚ t=time). On the other hand‚ for accelaration you will use the formula a= vf-vi/t (a=acceleration‚ vf=final velocity‚ vi= initial velocity‚ t=time). Average speed is how fast something is moving; the path distanced moved per time. Acceleration is the

Abstract :The purpose of the experiment is to explore elastic and inelastic collisions in order to study the conservation of momentum and energy. The guided track‚ carts‚ photogates ‚ 250 g weight and picket fences were the primary components used in the procedural part of the experiment. Each experiment involved the use of the photogates and picket fences to measure the initial and final velocities of both carts when they collide. The data was collected and translated to a graphical model for further

My lab results were similar to my hypothesis. My hypothesis was that the densest object would be the rubber stopper. In the lab results the densest object was the penny and the rubber stopper was second. My hypothesis was switched. My hypothesis was correct when I stated that the macaroni was the third densest object. My hypothesis was also correct for the dice‚ but the bead and the dice share the same density. So they are both the fourth densest item. I was wrong with my hypothesis when I placed

LAB # 5 Relationship Between Drop Height and Diameter of Plasticine Sphere PROBLEM: A student suggest that there is a proportional relationship between height at which a plasticine sphere is dropped and the diameter of the flattened part after dropping. Design an experiment to determine if this suggestion is true or not. AIM: To investigate the relationship between the drop height and the flattened part of a plasticine sphere after being dropped. HYPOTHESIS: As the height of the sphere plasticine

Damped Harmonic Motion Erica Partner: Steven November 8‚ 2012 Abstract During this experiment‚ the effects that the size of an object had on air resistance were observed and determined. To do this‚ a spring was set up with a circular object hanging at the end. After the spring constant of 9.0312 N/m was measured‚ equations were used to determine a calculated frequency‚ that being 7.252 Hz. Four trials—each with a different sized‚ same massed object—took place where the object was pulled

She think one who doesn’t worry to much about being a good parent. What are some of the common problems that children might have? With little ones the most common problems are kind of book standard‚ behavior‚ and terrible twos. Why is play important in the parent-child relationship? It’s definitely
