Mr. Moss THE LAB OF ATWOOD Procedure: The purpose of this experiment was to verify the predictions of Newton’s Law for an Atwood machine‚ a simple machine constructed by hanging two different masses and from a string passing over pulleys and observing their acceleration.. Newton’s Law predicts that the acceleration should be proportional to the difference between the masses and proportional to their sum‚ where = 9.8 m/s2 is the acceleration due to gravity.

Lab 106 Static and Kinetic Frictions Objectives: Our objectives are to measure the static and kinetic frictional forces using force sensors. Also‚ to determine the coefficient of static and kinetic frictional forces‚ amd the relationship between the frictional forces.

to obtain and compare the spring constants of 3 strings (soft‚ medium‚ and hard) obtained in 2 ways (using the energy chapter and the dynamics chapter)‚ to confirm that Hooke’s Law is valid over a range of initial displacements‚ and to find the acceleration due to gravity on unknown Planet X. Problem: What are the spring constants of 3 strings (soft‚ medium‚ and hard) and how do they compare? Theory: To find the spring constants of each string‚ we can calculate the velocity that the string is moving

PHYS 111N Experiment 06: Friction Submitted by: Porsha Renee Sumner Lab Partners: Amber Carter‚ Emily Rawles‚ Clayton Scott Wednesday‚ March 6‚ 2013‚ 9:00 AM Lab Instructor: Uttar Pudasaini Introduction In this experiment we will be examining how the kinetic friction coefficient is altered by changing the mass‚ surface area‚ speed‚ and material contacting each other. In order to find this value‚ we will be using a pulley apparatus that will allow us to measure the average velocity and manipulate

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

At any given time‚ both balls have the same y-position‚ y-velocity‚ and y-acceleration (g= 9.8 m/s2)‚ despite having different x-positions and x-velocities. Procedure/Raw data: This experiment was completed using the already mounted projectile launcher (ME-6800). In this experiment‚ the program measures the flight times of two

to show that the acceleration is proportional to the force causing the motion. Theory Newton’s second law of motion states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to the total mass. a = net force/ total mass If an object is acted on by a net force ‚ it will experience an acceleration that is equal to the net force divided by the mass. Because the net force is a vector‚ the acceleration is also a vector‚
