2.6.1 Draw a vector diagram to show that the acceleration of a particle moving with uniform speed in a circle is directed toward the centre of the circle. Review of basic kinematics: If the acceleration and velocity of an object are parallel (or anti-parallel) then the object’s speed will increase (decrease). If the acceleration and velocity of an object are perpendicular then only the direction of the velocity will change and the speed (i.e. the magnitude of the velocity) will remain constant.

It was not easy either. I can deal with everything but these uniforms." The both of them wore a white dress shirt and black tie that was covered by a red colored blazer‚ blue pants‚ and black shoes. "You’ll get used to it. I bet you’re only complaining because you have to tuck your tail in." "That’s one reason and

Newton’s second law of motion (Car vs Suv) According to newton’s second law of motion‚ Acceleration is produced when a force acts on a mass. The greater the mass is‚ the grater the acceleration is needed to move forward. This law basically states that a force applied to the objects changes its velocity overtime in the direction of the force that is applied‚ the acceleration is directly proportional to the force‚ as an example‚ if pushing on an object‚ causing it to accelerate‚ and then you push

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

The International Associations of Chiefs of Police started this program in 1929 as a means to have reliable uniform crime statistics for the nation. Law Enforcement Executives‚ Students of Criminal Justice‚ Researchers‚ Members of the Media and the public at large have used the Uniform Crime Reporting (UCR) as their starting place for information on crime across the nation. The UCR divides offenses into two groups‚ Part I and Part II crimes. The UCR program collects data about Part 1 offenses

Americans are hurt or killed in car accidents. Many factors can play into an accident. Road condition‚ mechanical failure‚ driver error‚ or simply an ’act of God’? Despite the countless reasons for a car accident‚ one factor is always present‚ no matter what the case: physics. Every accident that has ever occurred has involved physics. Using references found in the class text‚ in science journals‚ and on the Internet‚ I will prove this to you. Take‚ for example‚ two cars traveling in opposite directions

Cars once considered a luxury is now a necessity. The reasons for these drastic changes are two‚ 1. The residential areas have spread far and wide making cars indispensable. 2. Money at disposal and boom everywhere has made the purchase of cars possible by one and all. The Public transport system played both by the Government and private sector suffers serious drawbacks such as heavy crowd‚ negligent and rash driving undue consumption of time and unreliable operations. These are now

Hybrid cars: Are Hybrid Cars Becoming Safer or More Harmful to the Environment? I. Introduction Hybrid cars have a very special technology because they boast two power sources: a regular gasoline engine and an electric motor powered by a huge battery unlike conventional cars which have only regular gasoline engine. These components generally work in tandem‚ though the exact mechanism varies depending on the car. When the car is at stop‚ the engine shuts off. While you push the accelerator

People should decide which transportation they should get it. People now days know that the fossil fuel and burning gas can make the world to get warmer. We‚ the people know that the ozone layer. We know that burning fossil fuel can destroy the ozone layer. If the ozone layer destroys‚ the world will get warmer and

What are cars? What are motor cycles? Briefly‚ how do they contrast? How do they compare? What are their prices at the surface level? Thesis Statement: This essay seeks the comparison of cars and motorcycles. II. DEVELOPMENT Comparison a) Both cars and motorcycles are vehicles for transporting one or more persons. b) Both cars and motorcycles need fuel. Fuel serves a vital art in both cases as it supplies the energy required are the engines to work properly. c) Both cars and motorcycle
