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‚

reduces to two scalar equations. One for each of the necessary components. We calculate the components of the vectors to be added. For the coordinate system selected we have: vnet x = vbx + vrx = 3 + 0 = 3 mph ; vnet y = vby + vry = 0 + 4 = 4 mph The answer for the net velocity can be specified in two equivalent ways. One way is to specify the two components for the net velocity (as done above). The second method is to state the magnitude and direction for vnet. |vnet| = 3 + 4 2 = 25 = 5 mph.

1) A 4-kg mass moving with speed 2 m/s‚ and a 2-kg mass moving with a speed of 4 m/s‚ are gliding over a horizontal frictionless surface. Both objects encounter the same horizontal force‚ which directly opposes their motion‚ and are brought to rest by it. Which statement best describes their respective stopping distances? (A) The 4-kg mass travels twice as far as the 2-kg mass before stopping. (B) The 2-kg mass travels twice as far as the 4-kg mass before stopping. (C) Both masses travel the

was made into 3D movie this year------the 100 anniversary of Titanic being sunk. The movie Titanic is close to the real accident happened on April 14th‚ 1912 and there’s a lot of physics involved in the movie. We have to admit that James Cameron really spent plenty of time on the causation of the accident. ① physics side note: Pressure (√) At the beginning of the movie‚ there is a group of people who want to find the invaluable “Heart of the Ocean”. They used submarine to get 3821 meters under

1. A physics book slides off a horizontal table top with a speed of 1.10 m/s. It strikes the floor in 0.350 s. Ignore air resistance. Find the height of the table top above the floor; the horizontal distance from the edge of the table to the point where the book strikes the floor; the horizontal and vertical components of the book’s velocity‚ and the magnitude and direction of its velocity‚ just before the book reaches the floor. (Considering the direction to be negative downwards) Answers [0.600

Introduction I have chosen to investigate a factor that affects the output of a potential divider circuit. A potential divider is resistors connected in series across a voltage source; used to obtain a desired fraction of the voltage. A resistor is a device having resistance to the passage of an electric current which affects the output voltage (Vout). The factors that I could investigate are changing the resistance of r2 and record the output (Vout)‚ or use a light-dependent resistor (LDR) and change

ARCELIA ARRATIA MEASUREMENT OF LENGTH‚ MASS‚ VOLUME‚ AND DENSITY PHYSICS LAB REPORT Physics is the scientific study of matter and energy and how they interact with each other. Physics utilizes the scientific formula to test hypothesis and calculate matter such as density. Tools were created to measure material in a laboratory and have been perfected to reduce error. In this experiment measurement of length‚ mass‚ volume and density will be obtained through instruments of measuring
