Summary The objective of this report is to find the Moment of Inertia of a disc by means of investigating the use of rotational motion. We then used the results of the experiments to plot a graph showing the relationship between the mass of the weight with the time taken by load to pass the distance of length of the string. Three different size discs were used in these experiments to determine the influence the size of a disc will have on its Moment of inertia. The outcome showed that the larger

Module 3: ROTATIONAL KINEMATICS Reference Book: Properties of Matter – Dr. Tofazzal Hossain MOMENT OF INERTIA: According to Newton’s first law of motion‚ “a body must continue in its state of rest or of uniform motion along a straight line‚ unless acted upon by an external force.” This inertness or inability of a body to change by itself its position of rest or of uniform motion is called inertia. Exactly in the same manner‚ in case of rotational motion‚ also we find that‚ a

Senior Moments and Alzheimer’s: The Top Five Questions to Ask Your Doctor Everyone forgets something at times. It may be where they put their car keys‚ a phone number they have known for years or what time an appointment is. This happens to people of all ages‚ not simply seniors. The elderly‚ however‚ often worry when this occurs and wonder if they are showing the early signs of Alzheimer’s disease. Here are five questions to ask your doctor if you are concerned about forgetfulness. 1. What is the

Learning how to ride a real bicycle was a nerve wracking moment. * I woke up one sunny morning to find my grandpa sitting on the edge of my bed. I was curious as to what he was doing there‚ but then grew excited when he informed me that I was ready to learn how to ride a bike without any training wheels. I had been riding with training wheels for almost a year and felt like I was ready to take the next step in growing up. Even though I had some doubt‚ my grandpa and I went outside and

experienced moments that leave an undeniable stain on their being. Whether good or bad‚ such moments can stick to people like gum underneath a shoe. In Moments of Being‚ Woolf experiences one such moment. Having the time of her life on a fishing trip with her father and brother‚ the fun leads to tragedy as her father reveals he no longer wishes to indulge in fishing. Woolf too loses her passion for fishing. Woolf uses description‚ tone‚ and metaphoric language to show the moment is always by

Proud Moments in our history Canada has had many proud moments in the past 100 years that makes us who we are now. Vimy Ridge was one of our first proud moments in the 1900s where all four Canadian divisions in World War I fought in one battle together. After the First World War Canada became its own country by the Statute of Westminster stating that we were no longer was about of Great Britain. In the 1920s Canada invented many useful things that we still use today like the telephone‚ radio

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
