Moment of Inertia Formula The Moment of inertia is the property by the virtue of which the body resists angular acceleration. In simple words we can say it is the measure of the amount of moment given to the body to overcome its own inertia. It’s all about the body offering resistance to speed up or slow down its own motion. Moment of inertia is given by the formula Where R = Distance between the axis and rotation in m M = Mass of the object in Kg. Hence the Moment of Inertia is given in Kgm2

Marble-lous Momentum Question: What happens to momentum when one marble collides with other marbles? Hypothesis: If a marble collides with increasingly more marbles‚ then the momentum will be transferred more slowly to the final marble‚ because momentum is conserved through an inelastic collision‚ but a longer distance will have be traveled by the kinetic energy. Independent Variable: The number of marbles. Dependent Variable: The momentum of the first marble and final marble. Control Variables:

The moment of inertia is a measure of an object’s resistance to changes in its rotation. It must be very specific to the chosen axis of rotation. Also‚ it is specific to the mass and shape of the object‚ including the way that is mass is distributed in the object. Moment of inertia is usually quantified in kgm2. An object’s where the mass is concentrated very close to the center of axis of rotation will be easier to spin than an object of identical mass with the mass concentrated far from the axis

ADAM BAIN AND THE PRICE MOMENTUM STRATEGY In February 1995‚ Adam Bain‚ investment advisor in the London‚ Ontario branch of RBC Dominion Securities Inc. (RBC DS)‚ was considering whether or not to implement a price momentum strategy for his clients. Trend and Cycle‚ DS’s technical research department‚ had recently circulated a copy of a study which described a simple price momentum model and referred to its “startling results” based on back testing the strategy over a 15 year period. The Trend

Experiment Title: Torsion Vibration. Introduction : Torsion is the twisting of a metallic rod shaped object‚ when a torque is applied on two sides’ perpendicular to the radius of a uniform cross-sectional bar. Objective : Determining the natural frequency of a system undergoing tortional vibration. Theory : Using Newton’s second law of tortional system. ( [pic] ………………….

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
