Velocity— Is speed in a given direction‚ and is also a vector. Acceleration— is the rate of change of velocity in a given direction (velocity/time). The unit in SI is metres per second

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‚

Rosalind Franklin: The Unrecognized Collaborator The video begins by introducing Francis Crick and James Watson and speaking about their contributions on the discovery of the double helix in DNA. However Watson and Crick could not have made their discovery without the research and contributions of one unrecognized scientist: Rosalind Franklin. The video talks about Rosalind’s early life and then shows us the legacy that she left behind in science. From an early age Rosalind was extremely intelligent

colloidal system consists of two separate phases: a dispersed phase (or internal phase) and a continuous phase (or dispersion medium). A colloidal system may be solid‚ liquid‚ or gaseous. Many familiar substances are colloids‚ as shown in the chart below. As well as these naturally occurring colloids‚ modern chemical process industries utilize high shear mixing technology to create novel colloids. The dispersed-phase particles have a diameter of between approximately 5 and 200 nanometers.[2] Such

Reflection (physics) From Wikipedia‚ the free encyclopedia The reflection of Mount Hood in Mirror Lake. Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light‚ sound and water waves. The law of reflection says that for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected

Light‚ Color‚ and Sound - 4th Six Weeks Project Fiber Optics Sara McCormack‚ Special Harris‚ K’sandra Cunningham‚ and Arkayza Ross Light‚ Color‚ and Sound – Fiber Optics An optical fiber is made up of a core‚ cladding‚ and a buffer. The cladding moves the light along the core by using total internal reflection. The core and the cladding are usually made of high-quality silica glass‚ but they can both be made of plastic as well. Connecting two optical fibers is done by fusion splicing
