[pic] The product of average force and the time it is exerted is called the impulse of force. From Newton’s second law [pic] the impulse of force can be extracted and found to be equal to the change in momentum of an object provided the mass is constant: |[pic] |Calculation | The main utility of the concept is in the study of the average impact force during collisions. For collisions‚ the mass and change in velocity are often

The Devil in the Shape of a Woman Review The Devil in the Shape of a Woman is a pretty interesting book. Its only interesting cause it’s about the history of witch trials‚ and things like that kind of tickle my interest. It had its moments where I wanted to put it down cause it got so boring‚ but overall it was a decent read. I learn a couple of new things about the witch trials reading this book. Like parliament making a law in 1542 saying that witch craft was a capital crime. I learned

Porter’s 5 forces analysis is a framework for industry analysis and business strategy development developed by Michael E. Porter in 1979 of Harvard Business School. It uses concepts developed in Industrial Organization (IO) economics to derive 5 forces that determine the competitive intensity and therefore attractiveness of a market. Porter referred to these forces as the microenvironment‚ to contrast it with the more general term macro environment. They consist of those forces close to a company

= 300g 9.8 3. Explain the effect of mass on Hooke’s Law. Hooke’s Law states that the restoring force of a spring is directly proportional to a small displacement. Applying a mass to the end of the spring stretches it‚ changing the length from its original equilibrium position of rest‚ to a new (lower) equilibrium position. At this position‚ the vertical restoring force of the spring balances the weight and the downward pull of gravity is balanced by the upward pull of the spring

............................... 7 AIM To show that three forces acting upon a body‚ in equilibrium‚ may be represented by a triangle of forces. (Vector addition) INTRODUCTION With this experiment we will show that a body in a state of equilibrium‚ with three forces acting in a singular plane. The following conditions must be met: * Moment of all three forces must pass through the same point. * Magnitudes of the forces can be represented by the sides of a triangle‚ each as a vector

Sherriff in their realistic portrayals of trench warfare present a new style of hero. These heroes can be related to because of their strengths but also their weaknesses. In order to fully appreciate this‚ it is important to explore the setting from which these extraordinary men appear. In “Journey’s End” we see Sherriff utilise the very nature of his art form. He does this by making use of his characters physical presence when performing‚ as a play is essentially a visual experience. His use of such

Compare and contrast the way in which Heaney and Clarke portray childhood experiences Blackberry Picking by Seamus Heaney and Stealing Peas by Gillian Clarke both approach passion and disappointment in life by describing childhood experience. They explore love and regret through the description of childhood and nature; Blackberry Picking through the explicit meaning of picking blackberries but them decomposing‚ and Stealing Peas through the explicit meaning of children stealing peas from pea rows
