Physics Laboratory Report Sample PHY 223 Lab Report Newton's Second Law Your Name: Partner's Full Name(s): Date Performed: Date Due: Date submitted: Lab Section: (number) Instructor: (Name) Introduction We verified Newton's Second Law for one-dimensional motion by timing an accelerated glider moving along a flat track. We varied both the accelerating force and the mass of the glider. We found that for a given force the acceleration of the glider was inversely proportional to the mass of the glider, in agreement with Newton's Second Law. Experimental Procedure Description of the Apparatus: A sketch showing the essential elements of the apparatus is presented in Figure 1. below: Figure 1 Experimental set-up The experiment was conducted using a glider (a low-friction cart) rolling on a smooth, flat, level track. One end of a string was attached to the front of the glider.
The equation used in the experiment was ∫F dt=∫dp=mvf-mvi The left side of the equation is the integral of force over a period of time and the right side being the change in momentum of the object. The equation used to calculate the magnitude of the change in momentum was: △p=m|vf+vi| To have the greatest likelihood of surviving an accident, the time/duration of the collision needs to be as long as possible. The greater the duration of the impact was, the more survivable the impact itself becomes. First the cart used was weighed for later calculations. There were four types of collisions performed.
Newton’s second law is: Force equals mass times acceleration F = m x a (1) On earth all mass accelerates downward toward the center of earth at 9.8 meters per second. Force is a vector and the direction must also be known. If two equal forces pull on a rope in opposite directions the rope will not move as the forces balance each other out, similar to what would happen in a “tug of war” game with equal forces on both sides. The main purpose of this experiment was to see if we could obtain a zero sum, equilibrium for a series of forces using measured direction by angle and measured weight so that forces equalized each other and added to zero. To determine vertical direction we used this equation for vertical distance.
1994 conclude that the real causes of this disaster were weak locks of the door and the stray signals produced by some pair of wires which made the opened itself without any command.

Experiment 8: Ballistic Pendulum Physics 1408-C1 10/23/2012 Abstract: This experiment explored the conservation of energy and conservation of momentum of a totally inelastic collision. We accomplished this by using a ballistic pendulum. With this device, a bullet is fired into a wooden block suspended as a pendulum, embeds itself in the block and causes the combined block-bullet system to swing to a particular angle. This angle was smaller during the short range setting (29.0 o) and larger during the medium range setting (45.6 o). In addition, the initial and final velocities due to the short range setting were smaller in comparison to the initial and final velocities due to the short range setting.
Thereafter, the relationship between drag and lift with regards to wind speeds was analysed. Thirdly, the relationship between the lift forces generated on an aerofoil with varying angles of attack was analysed. Finally, the relationship between Reynolds number and wind tunnel testing was briefly described. The report is then concluded with a list of recommendations to improve further wind tunnel testing in terms of accuracy. ------------------------------------------------- Content Page ABSTRACT 2 CONTENT PAGE 3 1.0 INTRODUCTION 4 1.1 Purpose 4 1.2 Background Information 4 1.3 Methodology 4 1.4 Scope 4 2.0 EQUIPMENTS AND APPARATUS 5 2.1 Wind Tunnel 5 2.2 Asymmetrical Aerofoil 5 2.3 360° Protractor 6 3.0 PROCEDURES 7 3.1 Experiment 1 : Familiarization of wind tunnel 7 3.2 Experiment 2: Measuring Drag 8 3.3 Experiment 3: Measuring Lift 8 3.4 Experiment 4: Investigating Angle of Attack 8 4.0 RESULTS AND OBSERVATIONS 9 4.1 Drag vs. Wind Speed 9 4.2 Lift vs. Wind Speed 10 4.3 Lift vs.
Coefficient of Friction- Post Lab Abstract The purpose of the experiment was to determine to coefficient of friction on a block sliding across a horizontal plane, and on the same block sliding down an inclined plane. This was done by first testing block, and how much weight on a string was needed to move the block at a constant velocity using a pulley system. The block weighed 0.2385 kilograms, and needed a hanging mass of 0.05 kg to move at a constant velocity. This means the coefficient of friction is 0.37. The second block was tested on an inclined plane, and the angle was found at which the block would move at a constant velocity.
Physics 2215 March 5th 2013 Newton’s 2nd Law The goal of the Newton’s Second Law Lab was to verify Newton’s Second Law by showing that acceleration is directly proportional to the net force when the mass is constant and the acceleration is directly proportional to the mass when net force is constant. Students were to use graphs to support their analysis of the data to determine if their data supports Newton’s Second Law of Motion. Each group used an air track. On the air track rested a glider to which a string was attached. The string was attached to a weight on a pulley system.
In this case, the standard deviation of your range measurements was used as the measure of uncertainty. The variables that contain uncertainty due to human error include: the initial height h (the error was represented by the standard derivation which was 0.0005) and the variance on the final distance calculations (standard derivation are shown in Table I – Exercise 2, 0.4358899, 0.01527525 and so on). As for decimal places causing uncertainty, rounding numbers were also involved in rounding vmin, vmax and v0. As shown in Table II, the measured range is
DEPARTMENT OF PHYSICS LAB REPORT FOR Title of Experiment: Newton’s Second Law Experimenters: Authors of this Report: Experiment Performed on: Monday, January 28th, 2013 Report Submitted on: Monday, February 4th, 2013 Teacher’s Assistant Name: Objective and Background Newton was the first one to identify the connection between motion and force. Newton’s second law of motion states that acceleration is dependent on two variables; the net force (F1 + F2 + F3 + F4 +...) and mass. This law states that the acceleration acting on an object is directly proportional to the net force and is inversely proportional to the mass of an object. For example; heavier objects require more force to move the same distance as lighter objects. Newton’s second law of motion is expressed as a mathematical equation: Fnet = ma (Force = mass*acceleration) A significant notion of this equation is that an object accelerates in the direction of the new force, and acceleration is created by the net force.
