Interpretations: 1. The time required for the objects with different masses to fall equal distances was equal. 2. The average speed of the two different masses was quite similar‚ within one tenth of a second of each other. 3. Yes‚ because physics theory says that objects free falling‚ where the only force acting on them is gravity‚ accelerate at the same rate no matter what their mass is. 4. The change in spacing of the dots tells us that the speed of the object is increased as it falls

Experiment 9: THE TANGENT GALVANOMETER; PURPOSE: In this experiment we will measure the magnitude of the horizontal component of the Earth’s Magnetic field by the use of an instrument called a tangent galvanometer. INTRODUCTION: A tangent galvanometer consists of a number of turns of copper wire wound on a hoop. At the center of the hoop a compass is mounted. When a direct current flows through the wires‚ a magnetic field is induced in the space surrounding the loops of

DISCUSSION Chemical equilibrium and its different applications were studied in this experiment. The Le Chatelier’s principle‚ which is the main principle behind chemical equilibrium‚ states that‚ “If an external stress is applied to a system at equilibrium‚ the system adjusts in such a way that the stree is partially offset as the system reaches a new equilibrium position.”[1] The “stress” can be a change in concentration‚ volume‚ pressure‚ or temperature that disturbs the equilibrium

Chemical equilibrium is the point at which the concentrations of reactants and products do not change with time. It would appear as if the reaction has stopped‚ but in fact‚ the rates of the forward and reverse reactions are equal‚ causing the reactants and products to be created at the same rate. This can be expressed mathematically in the form of the equilibrium constant. The following is the general equation for a reversible chemical reaction: aA+bB →cC+dD

The Relationship Involving Acceleration‚ Net Force‚ and Mass Giho Park Purpose The purpose of this lab investigation is to observe the relationship among the net force‚ mass‚ and acceleration of an object. Hypothesis/Prediction Part A If the net force increases with a constant mass‚ then the acceleration would increase‚ because the force would push the object to increase the velocity. Part B If the mass of the cart increases with a constant net force‚ then the acceleration would
