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

Unfortunately‚ I don’t know any of these people personally‚ so I would have to be broad and unspecific when describing them. I know that we have all read the same material‚ so we have that. I hope that my audience‚ especially my professor‚ has experience with poetry. Whether that is from taking English

Analytical Essay on Drama Trifles by Susan Glaspell Heidi Barnard South University Trifles’ By Susan Glaspell I believe had several small defining moments leading to the one larger defining moment‚ which brings together all of them together. The defining moment is the discovery of the dead bird hidden in the pretty red box‚ this leads back to smaller points such as her sewing and the bird cage. “ Here’s some red. I expect this has got sewing things in it. (Brings out a fancy box.) What a

energy = mgh‚ is equal to the (1) Gain in kinetic energy = 0.5mv2 + 0.5I 2 (2) where v = velocity of the mass centre down slope (m/sec) = angular velocity of wheel (rad/sec) = v/r‚ r is the axle radius when rolling I = Polar moment of inertia = mR2/2 Applying conservation of energy‚ equate equations 1 and 2 to derive an expression for the velocity v at the bottom of the slope. Using the linear equations of motion‚ find the expression for time t. Show these derivations in

operating mgr sin (θ ) ̈where: m = gymnast body mass g = acceleration due to gravity r = pendulum length (θ ) ̈= angular deviation from the vertical or handstand point This torque results in a rotational acceleration ((θ ) ̈) modulated by the moment of inertia (I(θ ) ̈= mr2(θ ) ̈). The system can therefore be described by the following equation (θ ) ̈+ g/r sin Θ = 0 To achieve the backward giant circle energy lost to frictional forces and the conversion of energy must be overcome.

Neither A nor B 4. The drawing shows three objects rotating about a vertical axis. The mass of each object is given in terms of m0 ‚ and its perpendicular distance from the axis is specified in terms of r0.

I wake up surrounded by suffocating darkness‚ gasping for a breath that won’t come‚ my heart pounding. I don’t know what time it is and for a minute I don’t know where I am‚ I’m still trapped in whatever hellscape I was in. It takes me another minute to realise that I am home in my bed‚ and another minute to calm my racing heart and even out my breathing. In and out‚ in and out‚ over and over again until I’ve calmed down. At this point I’m too exhausted to go to find my parents so I settle for trying
