Motion NCERT Chapter Questions and Answers and other Q & A Q1: An object has moved through a distance. Can it have zero displacement? If yes‚ support your answer with an example. Answer: Yes an object can have zero displacement even though it has moved through a distance. It happens when the object moves back to its original position i.e. final position coincides with the starting position. Example: Suppose an object travels from O to C and then comes back to original position O. Total

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

From the simulation different parameters such as altitude‚ velocity‚ acceleration and range for initial fuel flows were calculated. Two numerical methods‚ Euler’s integration and 4th order Runge-Kutta integration are used

Three main entrepreneurs of the 1920’s were Alfred Sloan‚ the founder of GM‚ Henry Ford‚ the founder of Ford Vehicles‚ and Richard Sears‚ the founders of the department store‚ Sears. Richard Sears started out his business as mail order catalogues but decided to expand and have actual stores where people would be able to come in and shop. Richards Sears started opening his retail outlets in 1925 and the stores turned out to be a great success‚ as Sears department stores are still in existence today

Old Dominion University PHYS 111N Experiment 10 Harmonic Motion Submitted by: Lab Partner: Lab Instructor: Introduction In this experiment we will investigate the simple harmonic motion of an object suspended by a spring that oscillates on a vertical plane and in a separate experiment was examine oscillations on a horizontal plane. In simple harmonic motion‚ the displacement from the equilibrium position is directly proportional to the force. The force generated is always directed toward

Projectile Motion Purpose: Apply the concepts of two-dimensional kinematics (projectile motion) to predict the impact point of an object as its velocity increases. Introduction: The most common example of an object that is moving in two dimensions is a projectile. A projectile is an object upon which the only force acting is gravity. That is to say a projectile is any object that once projected or dropped continues in motion by its own‚ and is influenced only by the downward force

A brief introduction of People’s Republic of China’s Tort Law Student Name: QIAN‚Xin Group: MLM09-01 Student Number:0892439 Table of Contents Background The Tort Liability Law of the People’s Republic of China (‘Tort Law’) which was passed on December 29‚ 2009‚ came into effect since July 1‚ 2010. It is believed that more and more public affairs could damage civil benefits as a result of the rapid development in china’s economy and society. As the response

when an apple fell on his head. This incident caused Newton to speculate why this had happened‚ and in turn he came up with the law of universal gravitation. While this story isn’t exactly true‚ some aspects of it actually are. Newton wrote about his observations of gravity over the span of several years and he eventually formulated the law of universal gravitation. This law states that all objects in the universe attract each other with a force that is proportional to their masses and inversely proportional

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
