surface‚ accelerating because of an unbalanced force. The rate at which an object travels down the slope is dependent upon how tilted the slope is; the greater the tilt of the plane‚ the faster the rate which an object will slide down. Thus‚ if a physics cart is released on at a steep slope‚ the acceleration of the cart is expected to roll down the slope at a faster rate. As shown in figure 1‚ when a cart is released on an inclined plane‚ there’s always two to four forces acting upon the cart – the

house for JL” had started. I began by cleaning my bedroom‚ I first had to get my vacuum cleaner‚ I started vacuuming‚ that took me at least 2 hours because I ended up vacuuming the entire house. I was sooo tired when I finished‚ I had 6 hours left before Jennifer Lawrence arrived‚ what should I do to impress her? I mean besides talking about physics? I decided I’d make some coffee for the two of us‚ while all of this happens I remember that the A/C turns on every 30 minutes for 30 minutes‚ so it is on

2.4 Galileo Galilei: Sixteenth-Century “New Scientist” 1. In your own words explain why Albert Einstein considered Galileo to be the “father of modern science” Albert Einstein considered Galileo to be the father of modern science because of how many of Galileo’s discoveries have become the basis of today’s science. 2. Why did Galileo choose to use a ramp to perform his acceleration experiment? Technology during Galileo’s time was still quite primitive. His experiment which required him to drop

I. Temperature Measurement 1. A thermometric property is a physical property that changes in a known way with temperature‚ and can therefore be used to measure temperature. The substance used as a thermometer must have a property that varies proportionally / linearly with temperature. [ In other words: When objects are heated or cooled‚ their temperatures change‚ along with some of their properties‚ these properties are known as Thermometric Properties.] Two commonly used thermometric properties

Objectives: • To be able to explain how the photoelectric effect experiment works and why a photon model of light is necessary to explain the results. • To study the effect of intensity of light on photoelectric experiment. • To estimate the Planck’s constant‚ h through the simulation. • To be determine how to calculate the wavelength of light‚ the work function of the metal‚ or the stopping potential‚ if given the other two. Beginning with the plate made of sodium. Keep all the parameters

Components of Force Vectors Equipment: String‚ spring scales‚ 1.00 kg hooked mass‚ supports‚ meter stick‚ protractor‚ 20-N spring scales. Objective: During this lab‚ you will investigate the relationship between the angle of an applied force and the magnitude of one component. You will compare your actual force with the theoretical force and provide a computer generated data table that calculates the theoretical values. You will graph your actual and theoretical values and provide a complete

Physics began when man first started to study his surroundings. Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the period of Greek culture that the first systematic treatment of physics started with the use of mechanics. Thales is often said to have been the first scientist‚ and the first Greek philosopher

Physics in Sports Introduction Billiards‚ Pool or 8 Ball are the names given to this game. For many of us 8 Ball is a game that we play at friends’ place or at pool houses‚ pubs and a good many other places. But when you are playing 8 Ball you would never really think about physics would you? But it is there‚ and it is in play everytime the cue hits the ball to make it curve‚ everytime you jump the ball over another or bounce it around the cushioned sides to get the white ball

1.0 Introduction of Investigation Investigation can be defined quite simply as a systematic fact finding and reporting process. It is derived from the Latin word vestigere‚ to “track or trace‚” and encompasses a patient‚ step-by step inquiry. Investigation is finding facts; it is akin to research conducted in the academic arena. Investigation is a multi-disciplined field of study. It encompasses law‚ the sciences‚ communications‚ and a host of other things. Investigation requires an inquisitive
