Exercises for Chapter 1 Kinematics 1. An impulsive retarding force of 3 seconds duration acts on a particle which is moving with a forward velocity of 60 m/s. The oscilloscope record of the deceleration is shown. Determine the approximate velocity of the particle at t = 9 s. [answer: -58 m/s] 2. A car can decelerate at 0.8 ‘g’ on a certain road. Find the total emergency stopping distance measured from the point where the driver first sights the danger for a speed of 100 km/hr. The time taken for

Apollo 13 Essay Have you ever wondered what it would be like to fly in space or work on the crew at NASA that helps the astronauts get home safely? These two jobs both use many of the laws of physics. In fact‚ almost everything they do involves physics. Apollo 13 is a movie that epitomizes what those jobs are like and how much physics is required. The three main laws of physics in the movie were Newton’s Law of Universal Gravitation‚ Newton’s First Law‚ and Newton’s Third Law. One main law in

Light Transmission Through Liquids With Different Viscosities Introduction Aim This experiment investigates the effects of different liquid viscosities on light transmission. The results of this experiment could greatly benefit marine biologists or other marine scientists. This would help them figure out how their flashlights would work in different water conditions in the ocean. Background Research Spectrophotometers are devices that measure the amount of light absorbed by a certain liquid

Abstract The goal behind this experiment was to estimate the distance a ball would travel after it falls a certain distance and bounces off a metal plate which has an angle of 45 degrees. To find this we had to take the basic equations for kinematics which are (1/2)at2=x and v=v0+at and combine them to make an equation that will help us solve for the distance the ball will travel after hitting the bounce plate. The equation came out to be R=g*(sqrt(2)/sqrt(g))*(sqrt(H)*sqrt(h))‚ as that g is

Why in the World we Need Derivatives Many years ago humans discovered that with the use of mathematical calculations many things can be calculated in the world and even the universe. Mathematics consists of many different operations. The most important that is used by mathematicians‚ scientists and engineers is the derivative. Derivatives can help make calculations of anything with respect to another event or thing. Derivatives are mostly common when used with respect to time. This is a very

INTRODUCTION Science (Latin‚ scientia‚ from scire‚ “to know”)‚ term used in its broadest sense to denote systematized knowledge in any field‚ but usually applied to the organization of objectively verifiable sense experience. The pursuit of knowledge in this context is known as pure science‚ to distinguish it from applied science‚ which is the search for practical uses of scientific knowledge‚ and from technology‚ through which applications are realized.

Asia Nichols Phase 1 IP August 29‚ 2012 The three important properties of every material are the type of atoms that created it‚ the method those atoms are organized‚ and the manner the atoms are attached together. Atoms are all substance that is made up of atoms. They are the smallest unit of an element which holds its uniqueness in an organic reaction. Atoms can refer to the term intimate or attached.
