Simple Pendulum Learning Objective: In this laboratory we observed the oscillation of the period of a simple pendulum. We measured two different masses and calculated the time it took at different lengths that it took the pendulum to swing. Theory: As simple as the pendulum appears what it generally consist of in this experiment and what is taken into consideration during every trail is the mass of the bob and the concentration at a point in the center of that bob. The bob starts from rest at a certain angle and once the bob is let go it goes to the opposite point and swings back and forth in a time frame that is averaged at the end. The motion is continued until friction comes in contact and slows it down.
Theory In this experiment we will be interested in only one direction of motion. We will measure an objects displacement as ∆x= xf-xi the difference in the final position from the initial position. The speed of the object we are studying will be determined by the distance traveled per change in time(t) , using the following equation: Speed avg= Distance traveled∆ time(t) . The equation we use to find the acceleration (a) for an object that starts from rest is: a= 2xt2. Experimental Procedure The procedures for this experiment were followed as outlined in the Physics 215 laboratory manual and background materials.
Lab 8: Ballistic Pendulum Objective: In this lab we used three methods to measure the initial velocity of a projectile from a spring gun. In the first experiment we used kinematics alone to determine the mean initial velocity for the projectile. In the second experiment we added a simple ballistic pendulum to derive the velocity of the projectile using the principles of conservation of momentum and energy. In the third experiment we used a physical pendulum, the equations for conservation of angular momentum and energy, and the equation for the period to determine the initial velocity of the projectile. Description: In these series of experiments the apparatus we used was a spring gun that for the first experiment shot a steel ball freely which eventually struck the floor.
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. The SI unit for force in the above equation is Newton (N), SI unit for accelerations is metre per second squared (m/s2) and the SI unit for mass is kilograms (kg). The objective of this experiment was to show the relationship between acceleration and force in a frictionless environment and to show the concept of mass (Lab#1). Other equations used in this experiment were: V22 = V12 + 2ad; used to find the acceleration for each weight V1 = Lt1 and V2 = Lt1; both used to find the acceleration Materials * Two vernier photogate timers * String * Glider * Blower * Air—cushioned track * Weights and Hanger * Pulley and clamps * Vernier Lab Pro Procedure and Observations 1. Two photogate timers, 60 cm apart, were set over the air track.
Fist name, last name Physics ### Lab: Rotational Equilibrium The purpose of this lab was to analyze the physical effects of torques on an object and all the factors that can influence the magnitude of its strength and force. In lecture, we learned that although the magnitude of the force can have a strong effect on the rotational velocity of an object, the location or displacement of that force can have an enormous impact on the force’s effectiveness to do work. In this experiment, we saw, first hand, how a small force can have as much of a dramatic impact on an object as a larger force if the displacement is right. The goal of this experiment was to balance a meter stick at its center of gravity using different weights on opposite ends of the stick. Making the left side our positive direction, and our right, the negative direction was essential in proving algebraically, the results of the experiment.
Newton’s Second Law Lab Purpose: The purpose of this experiment was to determine the relationships between mass, force and acceleration as well as to prove Newton’s second law Hypothesis: It was hypothesized that there would be an inverse relationship between acceleration and mass; as the value of the mass increased the acceleration decreased. As well it is hypothesized that there would be a direct relationship between the net force and acceleration; as the net force increases the acceleration increases as well. Materials & Method: The materials that were required to do the experiment were a metre stick; its purpose was to measure the amount of string that is going to be used to drag the cart. Next equipment needed for the lab was a dynamic cart; it was going to be dragged by the string with a mass on the other end and will find relationships between these two. Also string (about 75cm) was needed in this experiment which would help pull the cart with the help of the masses that were used.
Lab 9 Formal Report Abstract In this report, we begin our studies on oscillations that repeat themselves. This lab will attempt to prove theories based around idea conditions for period motion where mechanical energy is conserved. First, using a simple spring oscillator will allow us to show this motion relative to an equilibrium point described by its angular frequency. Then, other forms of oscillations will be observed using a rod pendulum and wooden pendulum. Lastly we will explore standing waves and how string oscillations become affected by the string mass density.
Projectile Motion Internal Assessment BY: Abel Giday Date: November 19, 2010 Design: Marble Direction of Marble Two Meter Sticks on Inclined Plain (to help direct marble) Photo Gate White Paper Inclined Plain Carbon Paper Table Table Hanging Weight Meter Stick Weighing Scale Plastic Bag and Stand (To capture Marble) Caliper The above diagram represents a method that can be used in order to investigate, Projectile motion. As the marble is released from a specific height on the inclined plane, two parallel meter sticks help guide the marble directly down the ramp. As the marble is rolling down the ramp with a certain velocity, it crosses through the Photo Gate which allows one to obtain an accurate reading of the marbles instantaneous velocity. The marble then drops of the table and falls to the ground due to the influence of gravity. As it hits the ground it lands on carbon paper that has been placed over another blank piece of A4 paper.
To identify the King of the Sports we applied six tests to each sport. The tests we applied were; agility, reaction time, power, speed, co-ordination and balance. In each lesson we played a match in the tested sport, and at the end of each lesson we rated the sport with marks out of 10 for each of the components. Results | Football | Rugby | Cricket | Tennis | Hockey | Badminton | Basketball | Agility | 8 | 8 | 6 | 7 | 7 | 9 | 7 | Reaction Time | 7 | 8 | 9 | 9 | 7 | 10 | 8 | Co-ordination | 8 | 8 | 8 | 8 | 8 | 9 | 8 | Speed | 9 | 8 | 6 | 9 | 7 | 8 | 7 | Balance | 9 | 7 | 7 | 8 | 7 | 7 | 7 | Power | 9 | 9 | 8 | 9 | 7 | 6 | 7 | 50,48,44,50,43,49,44 The results are shown in the table above and are shown in the graph. Discussion The results show that it is difficult to crown one sport as King of Sports.
