Exercise 1: Rectilinear Motion Background The average accelerations of a US Navy fighter jet takeoff to an US Air Force fighter jet takeoff are very different. The aircraft conditions are the same except the Air Force fighter is on a 12‚000-ft dry concrete runway and the Navy fighter is on the catapult of an aircraft carrier. (Hint: You will have to use two different methods because you are not given the catapult force‚ but you have the catapult distance. Assume aircraft is airborne after the catapult

Name(s)_____________________ HOOKE’S LAW and SIMPLE HARMONIC MOTION INTRODUCTION Any motion that repeats itself in equal intervals of time is called periodic motion. A special form of periodic motion is called Simple Harmonic Motion (SHM). Simple Harmonic Motion is defined as oscillatory motion in which the resultant force on the oscillating body at any instant is directly proportional to its displacement from the rest position and opposite in direction to its motion. For a spring system‚ this can be written

ENERGY CONSIDERATIONS IN PLANETARY AND SATELLITE MOTION Consider a body of mass m moving with a speed v in the vicinity of a massive body of mass M‚ where M >> m. The system might be a planet moving around the Sun‚ a satellite in orbit around the Earth‚ or a comet making a one-time flyby of the Sun. If we assume that the body of mass M is at rest in an inertial reference frame‚ then the total mechanical energy E of the two-body system when the bodies are separated by a distance r is the sum

source of sexual and cultural complexity‚ also provides an interesting comparison with Paul Smith’s Clint Eastwood: A Cultural Production. Smith’s book constitutes a major effort to treat a star seriously in the light of contemporary studies of the representation of the body and the contrast between the "real" body of the actor and "reel" body on the screen‚ both ree(a)ls being both inevitably different and inexorably linked together. Smith breaks new ground not only through the depth and extent of his

identified. I also have referred to explosions as divisions. Is this appropriate? Newton’s First Law of Motion: A body will remain at rest or moving with constant velocity unless acted on by an unbalanced force. Example: • Q: while traveling in train if one throws a ball up it lands on his palm though the train is moving. my doubt is that though the ball is detached from motion how does it manage to land on his palm though he is moving along with the train? • A: he ball

Dynamics describes the relationship between force and motion. Force? What is it? Put in simple terms‚ a force is a push or a pull. It pertains to any influence that causes a change in an object’s state of motion. • Contact Force A contact force is produced when there is direct contact between two interacting bodies. • Long-Range Force A long-range force is produced when one body influences the state of motion of another body even if these two bodies are separated by empty space. • Concurrent Forces

Newton’s Laws of Motion Embry-Riddle University Bernoulli’s Principle and Newton’s Laws of Motion Bernoulli’s Principle In fluid dynamics‚ Bernoulli’s principles states that an increase in the speed of the fluid corresponds to a decrease in pressure of the same fluid. Similarly‚ the decrease in pressure corresponds to a loss in the potential energy of the fluid. The principle is applicable to various types of fluids‚ which leads to Bernoulli’s equation. There are different
