I. Introduction Physics is the natural science that involves the study of matter and its motion through space and time‚ along with related concepts such as energy and force. More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy. Over the last two millennia‚ physics was a part of natural philosophy along with chemistry‚ certain branches

You throw the ball. You catch the ball‚" said a well-respected baseball manager by the name of Casey Stengel. Mr. Stengel was a baseball man‚ not a mathematician nor a physicist. Physics and mathematics can be applied to the game of baseball on every pitch‚ and on every swing of the bat. To understand the physics of the game‚ it is first necessary to look at the center of the game‚ the ball. Section 1.09 of the Official Baseball Rules states that the ball must weigh between 5 ounces and 5 ¼

The Physics of Baseball The sport of baseball has been around for over two hundred years‚ roughly since the 1800s. Invented by a man named Alexander Cartwright. It is known as “Americas past time.” Baseball is the national sport of the USA. The first baseball game played was in New York on June 19‚ 1845. And is played by thousands of people throughout the years. Much like any sport‚ it has changed with time. The first rulebook of baseball was issued in 1877. And it has been changing every year

Physics 4052 Spring 2004 Y. Kubota K. Wick Project Proposal for Physics 4052 Introduction You must begin to think about a possible experimental project to carry out next semester (Physics 4052). The reason for this is two-fold: first‚ it will introduce you to the process of proposal writing‚ which is an unavoidable and very important part of modern experimentation‚ and second‚ it will enable us to make any necessary plans for procuring equipment. To start you thinking about this process‚

What keeps the stopper moving in a circle? Purpose: Relate the variables involved in uniform circular motion Hypothesis: I predict that the velocity of the stopper will increase as the radius is shortened. Rubber stopper with a hole PVC tube or wooden spool 1. Measure the mass f the stopper and washer‚ m‚ and record it in the data and observations section. Then‚ prepare the experimental apparatus as shown in figure A. 2. Throughout this experiment‚ you will need to maintain a constant

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
