Perpetual Motion I will be researching perpetual motion and why it is said to be impossible. The reason I chose this topic is because I remember learning the laws of thermodynamics in my eighth grade science class. After explaining these laws‚ the teacher added‚ “…and that is why perpetual motion machines are impossible.” Since we have been studying related topics such as motion‚ gravity‚ and friction‚ I figure it would be a great time to learn specifically why it is considered impossible

Stop motion animation has a long history in film. It was often used to show objects moving as if by magic. The first instance of the stop motion technique can be credited to Albert E. Smith and J. Stuart Blackton for The Humpty Dumpty Circus (1897)‚ in which a toy circus of acrobats and animals comes to life. In 1902‚ the film Fun in a Bakery Shop used the stop-trick technique in the "lightning sculpting" sequence. French trick film maestro Georges Méliès used true stop-motion to produce moving title-card

Circular Motion Uniform circular motion is the movement of an object or particle trajectory at a constant speed around a circle with a fixed radius. The fixed radius‚ r‚ is the position of an object in uniform or circular motion relative to to the center of the circle. The length of the position vector of the circle does not change but its direction does as the object follows its circular path. In order to find the object’s velocity‚ one needs to find its displacement vector over the specific

Assessment Task #1: Part A Open ended investigation By Rex Whiticker Projectile Motion Abstract: The Project motion of a catapult being fired is varied by a range of factors that affect the path of the projectile. In this experiment‚ the angle of trajectory‚ mass of the projectile and change in initial velocity of the launch‚ were all factors considered in the end result to investigate the properties of projectile motion. The purpose of the experiment was to conduct a first-hand investigation to design

follows a path determined by the effects of gravitational acceleration and air resistance. Projectile motion is the act of projecting an object into the air at an angle when a curved path is an object follows when thrown or propelled near the surface of the earth.For example: a thrown football‚ an object dropped from an airplane‚ or a bullet shot from a gun.Projectile motion may only be used to solve mechanics problems if the acceleration is constant.The path followed by a projectile is

Investigating Projectile Motion Introduction Projectile motion is a type of motion that consists of horizontal and vertical motions which are independent from each other‚ known as vector components. For an object to be considered a projectile‚ it must not be self-propelled. Projectiles move horizontally at a constant velocity. However‚ they undergo uniform acceleration in the vertical direction‚ which is caused by gravity. An important aspect of projectile motion is that the time it takes

Projectile Motion The purpose of this lab is to study the properties of projectile motion. From the motion of a steel ball projected horizontally‚ the initial velocity of the ball can be determined from the measured range. For a given initial velocity‚ the projectile range will be measured for various initial angles‚ and also calculated by applying the theory for motion with constant acceleration. For further background information‚ refer to the sections in your textbook on projectile motion and motion
