Introduction.

The purpose of this experiment is to elaborate how the angular acceleration of an object is measured. The report also explains how the angular acceleration of an object can be made constant. In addition, the investigation aims to establish if there is an association between the moment of inertia and probability distributions.

Procedure

Angular Acceleration
The radius of the stepped pulley and the plastic disks are measured using the vernier calipers. The hanging mass is lowered and the apparatus is observed to ascertain that the disk is accelerating and that the friction is minimum. Logger Pro is used to measure Continue reading...

Introduction

The experimental objective for Lab 6: Acceleration Due to Gravity, was to find a precise value for the acceleration due to gravity using the method of free fall and the swinging pendulum method. For part A of the lab, a steel ball was dropped from an electromagnet landing on a reaction pad. While falling, a photogate was placed at certain heights recording the time over a distance in seconds and meters. The photogate measured the time from when the ball passed the photogate to when the ball landed on the reaction pad. For any free falling object, mass Continue reading...

Newton’s second law of motion is used to explain the behavior of objects when unbalanced or unequal forces act on them (Lawrence and Morningstar 5). The law particularly explains the acceleration of the object after being subjected to these forces. According to this law, an object’s acceleration is dependent on two primary variables; the net force that is acting upon this object and the object’s mass (Lawrence and Morningstar 5). The acceleration is directly proportional to the force (that is, if the force increases, the acceleration increases) and is indirectly proportional to mass (that is, if Continue reading...

Introduction

In this experiment, the positions of the burn marks were measured. These were then used to determine the time instants during at which the average velocities occurred. The data was then used to construct a graph of velocity against time instant. The experimental value of acceleration due to gravity was then determined from the gradient of the graph and compared to the theoretical value of acceleration due to gravity.

Solutions:

1(a) The liner reciprocating motion of the piston is converted into rotary motion of the
crank shaft by a connecting rod, which connects the piston rod to the crank. As can be seen above, because of the nature of the linkage, at the start the crank and the connecting rod remain in a straight line. As the piston moves downwards during the power stroke, point b starts to move clockwise. This is obvious because the piston coming down means the connecting rod has to accommodate the travel of the piston. Finally, when the piston reaches the extreme end, Continue reading...

INTRODUCTION

Newton’s second law postulates that acceleration of a body that results from a force being exerted on the body is inversely proportional to its mass and directly proportional to the force exerted. The assumption of newton's second law of motion is based on massless and frictionless bodies. The purpose of this report is to present the findings of an investigation to establish the force exerted on a spring. A spring can be considered to be an instrument that is used in the storage of elastic potential energy. The results will be tested to establish if they conform to Continue reading...

Lab Report: Circular motion

Introduction
The uniform circular motion experiment investigates the continuous motion of a body rotating about an axis. A body in circular motion has a dynamic velocity vector. Even though the rotation speed of the body is constant, the change in vector means that the body is in constant acceleration. The force that is responsible for the acceleration is referred to as centripetal force. The centripetal force keeps the body in its circular path and if retracted, the body will leave the path in a tangential direction relative to the circular path. Centripetal acceleration is the main difference between linear Continue reading...

Introduction

Purposes of the lab experiment were to analyze rotating effects of a force; to be familiar with torque, moment of inertia and angular acceleration and how these relate to each other; to check whether the angular momentum was conserved when a ring was dropped onto a rotating disk. In the lab, moment of inertia for a solid circular disk and a ring were evaluated. A solid disk and a ring; three photogates connected to the measurement box; a rotational assembly on a heavy “A” shaped base; set of weights; flag; string and pulley assembly; a rotating platform with a Continue reading...

1.0 Abstract
The report is divided into two major sections. The first section of the report deals with a discussion about fundamental physical quantities together with their SI units. The quantities highlighted in the report include Mass, length, time, temperature and plane angle. A discussion of the derived physical quantities together with their units has also been presented in clear detail. The second part of the report focuses on providing a discussion of two machines that apply thermodynamics and are used in oil and gas industry. The machines identified to apply Continue reading...

The Simple Pendulum

Introduction:
Objective of this experiment was to calculate the acceleration due to gravity after determining the time period. Another purpose of this experiment was to validate the value of acceleration due to gravity i.e. “g”. For validation purpose, the experimental value of “g” was compared with theoretical one. An ideal simple pendulum was used to perform this experiment. To decrease percent error, many measurements of time were taken.

Data Analysis:
Data analysis for Time period has been shown below-
Average period (s) = (1.80 + 1.78 + 1.80 + 1.78 + 1.79 + 1.78 + 1.78 + 1.78) /8 = 1.784
