between the armor of the enemy knights also they were used to throw hot tar to attack there enemies. It was also used to launch infected bodies into enemy camps to spread disease. Although they are very hard to create‚ they use very simple forms of physics to complete their task of destruction. The catapult has a basket or cup on the end of a movable arm strong enough and large enough to hold the weight of the object it is intended to hurl. Tension is applied to the arm‚ whether that be applied by

This reflection is divided into two parts: the importance of critical reflection and an evaluation of self. The first part will be drawing upon through the appropriate literature‚ and there are four points to prove the importance of critical reflection in personal development. It will be expounded and distinguish Reflection in action and Reflection on action. Then‚ the theory of Single and double loop learning will be introduced. Moreover‚ the reflection also includes the difficulties and challenges

intertwined around itself‚ but regardless of how big‚ fast‚ or gravity defying they are‚ they all use the same natural force – gravity. The more twisting‚ turning‚ flipping‚ and the faster a roller coaster goes‚ the more the coaster depends on the law of physics‚ not mechanics‚ to keep it moving. There is no onboard motor on roller coasters but they can still reach speeds that exceed the limits of a car on the parkway‚ while completing a curve‚ twist‚ rise‚ or plunge.

through a more advanced explanation. Roller coaster rides involve a great deal of physics. The ride often begins with a chain and motor which exerts a force on the train of cars to lift the train to the top of a tall hill. Once the cars are lifted to the top of the hill‚ gravity takes over and the rest of the ride works on energy transformation. There is no motor or engine that takes a train around the track. The law of physics is basically the engine of the train. At the top of the hill‚ the cars possess

AP10005 Physics I Tutorial 7 (Chapters 17‚ 18) 1. (17P11) A flower pot is knocked off a window ledge from a height d = 20.0 m above the sidewalk as shown in the figure below. It falls toward an unsuspecting man of height h =1.75 m who is standing below. Assume the man requires a time interval of Δt = 0.300 s to respond to the warning. How close to the sidewalk can the flower pot fall before it is too late for a warning shouted from the balcony to reach the man in time? 2. (17P15)

Session 1: A Critical Reflection As I start my new educational path I found myself reflecting back on my most recent work experience. I spent six years working directly in the shadow of a very demanding Office Manager. She received all the credit while I did all the work. Many nights I came home frustrated and in tears from her lack of respect and her threating ways. However‚ my pride in myself and my strong work ethics kept me going in everyday and doing the best job I could do. This past May‚ due

The physics of scuba diving Imagine swimming in the underwater world with all the creatures and all the beauty it holds. It is an amazing feeling to swim over coral reefs and see all the sea life up close and personal. So many scuba divers all over the world share a passion to scuba dive. Scuba diving has been a worldwide endeavor for centuries (1). Persian divers were making goggles for diving around 1300. A British engineer invented the air pump in 1771 and in 1772 a Frenchman tried inventing

Year 12 Physics 2014 ER – The Physics of Medicine Extended Response Task [Type the author name] This report will discuss how cerebrovascular disease‚ in particular ischemic stroke‚ can be diagnosed using magnetic resonance imaging scans. It will go through the different MRI sequences and the physics behind them. Evidence from two case studies are presented‚ which use the MRI sequences discussed within this report. Consequently‚ the recent advances in diagnostic techniques and methodologies will

“Cartoon Physics‚ Part 1” Nick Flynn centers “Cartoon Physics‚ Part 1” around childhood innocence. He very strongly urges not only parents‚ but anyone around a young child to not force upon them knowledge they do not need to know. Flynn captures the simple kid mind and harsh reality with tone‚ imagery‚ figurative language‚ and even the form of the overall poem. There is a stark contrast between tones in the passage. In the first few lines the tone is cold; detached. The actual physics of the never-ending
