Applied Physics

By Kaitlin Dyer

Session 1

In this session I defined velocity and acceleration, calculated velocity and acceleration, and explained the relationship between gravity and acceleration.

Session 2

In session 2 I defined the relationships among frequency, pitch, amplitude, and loudness. I also experimented with different sound waves, and listed the steps necessary to be able to hear sound.

Session 3

In this session I defined the term hypothesis, made a hypothesis about how different materials expand as heat is applied, tested my hypothesis, and defined and provided examples about three ways heat is transferred. (Convection, Conduction, and Radiation.)

Session 4

In this session I listed the steps of the scientific method, differentiated between an insulator and a conductor, and conducted experiments to measure a material's ability to conduct or insulate heat.

Session 5

In this session I verbalized how tinting sunglasses filters light, discovered how light waves travel, and determined which colors block the most and least amount of light. Also determined what color and yellow would block the most light together. It ended up being "Deep Blue" and Yellow.

Session 6

In this session I described the characteristics of laser light that make it different from ordinary light. I also demonstrated proper care and use of a laser, and experimented in my workstation with a laser light.

Session 7

In this session I demonstrated proper care and use of a laser. I also transferred sound waves through a laser beam, and used a beam splitter and mirrors to direct a laser beam.

Applied physics is used differently, depending on where and what it is used for. It differs from engineering because engineers solve well-defined problems, which applied physics is not. Applied physicists used applied physics for, an example, calculating how much radiation to give to a cancer patient. Lasers, which are a part of applied physics, are used for many things, including T.V., bar code scanners, etc. Applied physicists solve these complex problems for experiments and actual objects that are released as a product, to ensure that quality is in order. Applied physicists are very knowledgeable in science, mostly with things that include heat and energy transfer, along with velocity, inertia, and acceleration. They explain how heat is transferred through Convection, Conduction and Radiation. They also explain how energy cannot be destroyed, only changed.
