Determine what factors make a hot air balloon or a helium balloon float Student Instructions: 1. Why does a hot air balloon float even though it is so heavy? Hot air balloons float because the buoyancy force of the hot air is more that the

Height of Ball Drop v/s The Depth of the Crater | By Tejas Shah‚ IBDP Year 1 | | | | | | | * Aim- To find the relationship between the depth of crater and the height from which it is dropped. * Research Question- Does the height from where the ball is released affect the depth of the crater. * Hypothesis- If we increase the height of the drop of the ball; the depth of the crater would increase. This is because as there is loss in potential energy subsequently there

Rotational Dynamics Abstract Rotational dynamics is the study of the many angular equivalents that exist for vector dynamics‚ and how they relate to one another. Rotational dynamics lets us view and consider a completely new set of physical applications including those that involve rotational motion. The purpose of this experiment is to investigate the rotational concepts of vector dynamics‚ and study the relationship

Chemical Equilibrium Lab Report Aim: The aim of the lab “Chemical Equilibrium” is to observe the effects of changes in concentrations of products and reactants on the position of the equilibrium of given chemical reactions. Background Information: We are going to use our knowledge of the Le Chatelier’s principle in order to observe this experiment. The principle states that the equilibrium will shift in the direction that will minimize the effects of the change. This lab consists of two

Introduction: Solubility equilibrium refers to the dissolution of a compound in water. Specifically‚ the degree to which a compound is soluble (Tro‚ 739). This can be measured using the expression Ksp = [Mb+]a[Xa-]b‚ in which Ksp represents the solubility product constant (Thorne‚ 90). This constant is important because it does not change at a given temperature‚ regardless of the solution a compound is in; a smaller constant would indicate lower overall solubility. It is important to note that

Independent Assessment Physics Lab (SL): Cantilever Flexion Cherno Okafor Mr. Ebrahimi SPH4U7 October 21st‚ 2012 Introduction Purpose: The purpose of this Physics Lab is to investigate what factors determine the amount of flexion of the cantilever. Hence‚ the objective is to establish a relationship between the length of a cantilever‚ which may give some insight into the physics of cantilevers. Hypothesis: If one increases the length of a cantilever‚ one would expect there to be an
