Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences

A successful crime investigation depends upon the collection and analysis of various kinds of evidence. Forensic scientists classify evidence in different ways and have specific ways of dealing with it. One major distinction is between physical and biological evidence. Physical evidence refers to any item that comes from a nonliving origin‚ while biological evidence always originates from a living being. The most important kinds of physical evidence are fingerprints‚ tire marks‚ footprints‚ fibers

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

The Method of Scientific Investigation Scientific investigation in my own words is when someone breaks down a problem to find a solution scientifically‚ but there can be more to it than just investigation a problem scientifically. Thomas Huxley explains scientific investigation in more depth in his “The Method of Scientific Investigation” essay‚ what is he trying to say in this passage? It could be many things‚ it could be nothing or it could be something‚ we’re basically trying to find out what
