1.1 GRAVITY AND GRAVITATIONAL FIELDS 1.1.1 Define weight as the force on an object due to a gravitational field. Weight is the force experienced by an object due to the presence of a gravitational field. This force is directly related to the strength of the gravitational field acting on an object and the mass of that object. m = mass‚ g = acceleration due to gravity m = mass‚ g = acceleration due to gravity Fg = mg Fg = mg 1.1.2 Explain that a change in gravitational

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

** Atom and Introduction to Nuclear physics ** Introduction Alpha-particle scattering 2.1 Experimental set-up ➢ Alpha particle o is a high-energy helium nucleus with 2 protons and 2 neutrons. o has 2 positive charges. ➢ Gold foil was chosen since it has a high atomic mass. Thin gold foil‚ ~10-6m was bombarded by high-energy alpha particles. ➢ Angular deflections/ scattering of alpha particles were measured by observing

escape. As a student‚ we should be aware of what is happening in our environment and society and do something‚ in our smallest little ways‚ to help preserve our only home. We are given an INVESTIGATORY PROJECT in our physics class to somehow lessen our environmental problem. Our project to be investigated is the HOMEMADEOR NATURAL INSECTICIDE. We all know‚ that our Ozone layer is getting thinner and thinner every time because of the chemicals we use daily. Now‚ to lessen

Application Of Physics In Medicine Medical physics is generally speaking the application of physics concepts‚ theories and methods to medicine. A medical physics department may be based in either a hospital or a university. Clinical medical physicists are often found in Diagnostic and Interventional Radiology‚ Nuclear Medicine and Radiation Oncology. However‚ areas of specialty are widely varied in scope and breadth e.g.‚ clinical physiology‚ neurophysiology (Finland)‚ and audiology
