The Relationship Involving Acceleration‚ Net Force‚ and Mass Giho Park Purpose The purpose of this lab investigation is to observe the relationship among the net force‚ mass‚ and acceleration of an object. Hypothesis/Prediction Part A If the net force increases with a constant mass‚ then the acceleration would increase‚ because the force would push the object to increase the velocity. Part B If the mass of the cart increases with a constant net force‚ then the acceleration would

member in two scenarios (going up and down the stairs of the second floor and the third floor of the Main Building) wherein weight was also considered and following this‚ the power output of each member was also computed. Using the Logger Pro‚ the kinetic and potential energies of a ball in free fall were graphed and compared. At the end of the experiment‚ it was said that member #2 was the most “powerful” among the group since she had the highest power output both in going up and going down the stairs

The kinetic energy of an object attached to a horizontal ideal spring is denoted by KE and the elastic potential energy by PE. For the simple harmonic motion of this object the maximum kinetic energy and the maximum elastic potential energy during an oscillation cycle are KEmax and PEmax ‚ respectively. In the absence of friction‚ air resistance‚ and any other nonconservative forces‚ which of the following equations

KINETICS OF THE ACID DECOMPOSITION OF THIOSULFATE Aqueous solutions of thiosulfate‚ S2O32-(aq) are stable if neutral or basic‚ but decompose quickly when the thiosulfate is dissolved in acid according to the equation: Sulfur dioxide is a gas at room temperature‚ but is very soluble in water. Sulfur‚ a water insoluble solid‚ forms a colloidal suspension. As a result‚ the solution first becomes cloudy and then opaque. We can take advantage of the developing opacity of the reaction system to do a

The Physics of Badminton Gerard Ramos Physics 4A Prof. Scott Hildreth I would like to start off with a light introduction to the sport of Badminton. Badminton is a sport that isn’t too popular in the United States; some people would even say that it shouldn’t even be called a “sport”. The majority see badminton from a “back-yard sport” point of view‚ part of this is due to the lack of actual badminton court facilities in America‚ also because it’s a bit expensive to play. Badminton is not

Since the birth of Physical Review Letters fifty years ago‚ condensed matter physics has seen considerable growth‚ and both the journal and the field have flourished during this period. In this essay‚ I begin with some general comments about condensed matter physics and then give some personal views on the conceptual development of the field and list some highlights. The focus is mostly on theoretical developments. DOI: 10.1103/PhysRevLett.101.250001 PACS numbers: 01.30.−y The transistor

Basic equations of fluid statics | | | | | | | | | | | | | | | | An equation representing pressure field P = P (x‚ y‚ z) within fluid at rest is derived in this section. Since the fluid is at rest‚ we can define the pressure field in terms of space dimensions (x‚ y and z) only. Consider a fluid element of rectangular parellopiped shape( Fig : L - 7.1) within a large fluid region which is at rest. The forces acting on the element are body and surface forces. | | Body force

some of the physics involved in the sport of soccer. I chose soccer because I have played it my whole life and it is one of my favorite sports. I thought it would be interesting to learn about some of the physics involved in something that I do almost everyday and has been a big part of my life for as long as I can remember. My poster depicts the physics involved in kicking‚ the ball rolling across the field‚ and bending the ball. Kicking a soccer ball involves transferring kinetic energy‚ or movement

3. Recent technological developments have allowed greater use of the electromagnetic spectrum 1. describe electromagnetic waves in terms of their speed in space and their lack of requirement of a medium for propagation In space (a vacuum) electromagnetic waves travel at the speed of light‚ a constant equal to 3.00108ms1. Unlike sound waves‚ electromagnetic waves do not vibrate particles‚ therefore they do not need a medium (substance) to propagate (move). 2. identify the electromagnetic wavebands
