Chapter 1 Scientific Method: (4 & 5 are combined) 1. Observe Closely observe the physical world around you. 2. Question Recognize a question or a problem. 3. Hypothesize Make an educated guess—a hypothesis—to answer the question. Must be able to be proven rright or wrong(false or true). 4. Predict Predict consequences that can be observed if the hypothesis is correct. The consequences should be absent if the hypothesis is not correct. 5. Test predictions Do experiments to see if the consequences

Soccer Physics In this paper‚ I will explain the physics concepts of air pressure‚conservation of energy‚ gravity‚Inertia‚ and impulse momentum as they relate to the sport of soccer. I will also explain how knowing these laws can benefit how you play. The first physics concept I will talk about is air pressure. When you kick a soccer ball more energy transfers to a highly pressurized ball‚ as for a non inflated ball‚ the motion of the kick goes into the ball instead of moving the ball

ME 304 – Experimental Engineering Spring 2013 Lab Report Experiment # 3 Bending of Beams Section # ThTh12 Group # 1 Ömer Ege Çalışkan Serhat Karakuz Noyan Uğur Renda Turgut Soydan 20.03.2013 Abstract In this experiment‚ a simply supported beam is used and the variations of deflection of a simply supported beam with load‚ beam thickness and material are investigated. It is found that the deflection of the beam changes linearly with the load and as the beam

It is employed to control the impact of the previous history of velocities on the current velocity. It directs the trade-off between global and local exploration abilities of the flying points. A larger inertia weight wmax facilitates global exploration while a smaller inertia weight wmin tends to facilitate local exploration to fine-tune the current search area [2]. w^(k+1)=w_max-(w_max-w_min )* ((k+1))/k_max (3.8)

The answer to the first question about feeling the motion of the Earth lies in Newton’s first law. The reason we cannot feel the motion of the Earth is inertia and frames of reference. Inertia is an objects tendency to stay in its current state while in a frame of reference only the motion between objects is meaningful. With the absence of external clues a person moving and sitting still feel the same stimuli. Since people’s

Module 3: Natural Forces Affecting the Driver Vocabulary: Please define six (6) of the following terms in your own words. Please do not just copy and paste the definition. 1. Inertia- Newton’s law of inertia it says that an object at rest tends to stay at rest and an object in motion tends to stay in motion 2. Potential Energy- Potential energy is the energy that matter has because of the way it’s positioned. 3. Kinetic Energy- Kinetic energy is the energy developed by an object when it is

Newton’s First Law of Motion explains that objects in a state of uniform motion tends to remain in rest unless an external force is applied to it. Galileo’s concept of inertia is termed “Law of Inertia”. Law of Inertia‚ an object in motion will continue in the same motion unless acted by an outside force. Aircraft in flight is an example of First Law of Motion‚ four forces on an aircraft; lift‚ weight‚ thrust‚ and a drag. Consider the motion of an aircraft at constant altitude‚ we can neglect the

In the first graph‚ the golf ball flew extremely higher than the wiffle ball when bounced off of the basketball. Therefore‚ it makes the forces unbalanced and allows the smaller balls to bounce higher from the motion of the larger balls. In the second graph‚ the golf ball also bounced significantly higher than the wiffle ball when bounced off of the volleyball. This means the more mass the top ball has‚ the more force energy is transferred into it. There was more energy transferred into the golf

Synchronous tie exhibits the typical behaviour that as power transfer is gradually increased a maximum limit is reached beyond which the system cannot stay in synchronism‚ i.e.‚ it falls out of step. 2. The system is basically a spring-inertia oscillatory system with inertia on the mechanical side and spring action provided by the synchronous tie wherein power transfer is proportional to sin d or d (for small d; d being the relative internal angle of machines). 3. Because of power transfer being proportional
