Objective: The objective of this laboratory was to theoretically calculate the moment of inertia of a disk and a ring and then to verify the moment of inertia for both objects through experiment. This laboratory shows that while the theoretical is not within the uncertainty of the experimental, both values are extremely similar to each other. Data and Analysis: Data: Table 1: The Angular Acceleration of No Ring and Ring Trial No Ring Ring 5g 4.57 ± 0.005 rad/s2 1.32 ± 0.005 rad/s2 10g 13.16 ± 0.005

Where I is the moment of inertia of the body about the axis of rotation. In this experiment
Abstract Moment of Inertia is the measure of an object’s resistance to changes in the rotation direction. It is the rotational analog of mass for linear motion. The relationship of moment of inertia to angular acceleration is similar to that of the mass to linear acceleration. In the experiment, the scalar form or the mass of moment of inertia was used. The determination of the moment of inertia of a disk and a ring and to compare the moment of inertia of the solid disk rotated at two different
The Moment of Inertia of the flywheel was obtained as follow: I = T / α = Fa (R2+R1) / (a / R2) = ((M4g) - (M4a) - (FFr)) (R2+R1) / (( S - ut ) / ( 0.5 t^2 )) / R2 = ((M4g) - (M4(( S - ut ) / ( 0.5 t^2 )) - (FFr)) (R2+R1) / (( S - ut ) / ( 0.5 t^2 )) / R2 • Torque is equal to the product of the moment of inertia and angular acceleration; therefore moment of inertia is equal and was calculated as the quotient of the torque and angular acceleration. • The torque was calculated as well as the
ABSTRACT Moment of Inertia (Mass Moment of Inertia) - I - is a measure of an object's resistance to changes in a rotation direction. Moment of Inertia has the same relationship to angular acceleration as mass has to linear acceleration. In this practical, the weights was attached to the hanger in order to determine the mass of inertia of a flywheel then the experimental values will be compared with the theoretical values. In this paper, the theory of mass moment of inertia are reviewed and discussed
Angular momentum is the relationship between Rotational Inertia and Rotational Speed. More simply, it is the tendency an object has to continue moving in a circle or spinning. Angular Momentum = Angular Velocity x Rotational Inertia When a figure skater pulls their arms closer to their body, they are reducing their Rotational Inertia, making themselves more aerodynamic. In order to sustain this and maintain their momentum, the Rotational Speed must increase. Angular Conservation Angular momentum
velocity and its moment of inertia. Just as a moving object's inertial mass is a measure of its resistance to linear acceleration, a rotating object's moment of inertia is a measure of its resistance to angular acceleration."2 Factors which effect a rotating object's moment of inertia are its mass and on the distribution of the objects mass about the axis of rotation. A small object with a mass concentrated very close to its axis of rotation will have a small moment of inertia and it will be fairly
The Hurdle Before a diver jumps off of a springboard, he does a sort of hop-skip step called a hurdle. After doing a few steps, the diver leaps up into the air with his arms raised. When he lands back down on the tip of the board, he swings his arms down past his legs and then up, leaping into the air and off of the board. The purpose of this hurdle is as follows: A diver cannot simply stand on the end of board, step off, and expect to have the power to go up or the momentum to rotate his
Fishing contains a wide variety of physics. when you cast you are using projectile motion and rotational motion. when you hook a fish it will often use the drag from the current agenst you. Immagine draging a fish through a swift current. You deal with the tention of your line, and the friction of the line through the guides. you also deal with friction when you use a drag. Reels One of the key components of your fishing gear is the reel. http://www.eangler.com/eangler/proshop/reels.asp
The spinning wheel by physics of its rotational inertia is stable. The greater the speed of the spinning wheel the greater the stability. The speed of a rotating wheel effects on how stable the wheel will be. Rotational stability of the wheel as it slows down the stability becomes less stable and as the wheel speeds up the stability increases this is why it is easier to ride a bike or motorbike the faster the wheels are spinning. A dirt bikes spinning wheel is stable even if it is not in if not
Catapulting though Time & Physics Hurling an object towards one’s enemy may seem as old as time itself. People have hurled fists at each other, thrown spears, and launched giant rocks into enemy territory. The use of catapults, and other objects that hurl projectiles, also seem as old as human civilization itself. The effectiveness of the catapult in flinging objects over a great distance and causing destruction is due to a few basic physics principals that govern force, energy, motion, speed

This is of interest in that the instrument to being used, a Fourier-transform infrared (FT-IR) spectrometer, can measure the vibrational and rotational transitions
digits used to represent the values. The equations of motion for any given airplane are non-linear in nature. It is linearised by making certain assumptions. The assumptions are as follows: The OX and OZ axes are the planes of symmetry. The polar moment of Inertia J is zero in XY and YZ is equal to zero. The mass of the airplane remains constant during the whole analysis. The aircraft is a rigid body. Earth is an inertial reference. Formulation of Equations of Motion: According to Newton’s Second Law of

In the figures: (a)=height of the pivot, (b)= length of the short arm, (c)= length of the long arm, while (v) and (V) are the velocities of (m) and (M), respectively, at the moment of launching.
Salsa has become an ever more popular dance in the United States, especially with the emergence of Latin artists including Marc Anthony, Ricky Martin, Jennifer Lopez, and Shakira. Go to any club or ballroom dance and you will hear a pulsating beat moving you out of your chair and onto the floor. Even Broadway has been affected by Latin music. For instance, Cell Block Tango in the smash hit Chicago has a driving Latin beat. It doesn't matter if you are partying in Miami or sipping martinis in Massachusetts
Anatomical Analysis Tae Kwon Do is a Korean, unarmed martial art and is best known for its kicks (Park, 2001). The roundhouse kick is a turning kick and happens to be the most commonly used kick during competition (Lee, 1996). For this reason, the roundhouse kick will be analyzed in reference to sparring competition. The roundhouse kick, a multiplanar skill, starts with the kicking leg traveling in an arc towards the front with the knee in a chambered position (Pearson, 1997). The knee is extended
W=mg Τ=Iα Τ=Fr; friction F=μN The most basic part of a succesful technique is a proper stance that is well grounded and solid. This helps in many ways, including providing the initial push behind a technique, grounding the karateka during the moment of impact, and providing a solid base from which to defend against an attacker. ... ... middle of paper ... ...rown into the rotation, the more energy is contained in the leg at this stage in the kick. The next stage of the kick switches to
Moment of Inertia of a Liquid in a Cylinder Exploration: Intro One night, out babysitting, I found myself playing with a toy garage, making little cars go down the ramp. You place the little car at the top floor of the toy garage and watch it go down. Some cars zoom down, others got stuck, others toppled over and flew off the track. This made me think of those heavy trucks filled with liquid and how they behave in a crash. Bulk liquid transport trucks when that are only partially filled are especially
Mechanical Motion Linear Motion Linear motion is motion in a straight line. [1] Steady linear motion is known as velocity which also can be defined as uniform motion in a straight line. As an example, cutting arm of a paper guillotine (Figure 1) is travelling in straight line from one side of the machine to the other. Figure 1: Example of linear motion Rotary Motion Rotary motion is motion that moves in a circle. [2] This type of motion was one of the first motions discovered in ancient times.
This photo is of a Washington State Cheerleader performing a full basket. To perform this stunt, 3 or 4 bases interlock their arms while the flyer stands crouched down on their arms. The bases dip down then quickly raise their interlocked arms, which are a platform for the flyer, and throw the flyer as high as they can into the air in a straight line as the flyer stands up. She performs a skill when she feels weightless at the top of the throw. In this photo, you can see that she is twisting her
