The Physics of Field Goal Kicking Physics is involved in all of our daily activities. Most of the time‚ however‚ physics is overlooked and never acknowledged. It is important to understand different aspects of physics because physics tells us how and why certain events occur. By definition‚ physics is the search for laws that describe the most fundamental aspects of nature: matter‚ energy‚ force‚ motion‚ heat‚ light‚ and other phenomena. There are many different sectors of physics‚ but we will

Characteristics and Nature of Waves In physics‚ a wave is a disturbance that travels through space and time‚ usually accompanied by the transfer of energy. Waves travel and the wave motion transfers energy from one point to another‚ often with no permanent displacement of the particles of the medium—that is‚ with little or no associated mass transport. They consist‚ instead‚ of oscillations or vibrations around almost fixed locations. For example‚ a cork on rippling water will bob up and down

Physics 1 – Mechanics and Heat Lecture Notes Prepared by: ENGR. HAROLD JAN R. TERANO‚ ECE Lesson 5 ROTATIONAL KINEMATICS AND DYNAMICS Uniform Circular Motion – an object moves at a constant speed along a circular path. Velocity is always tangent to the path in circular motion. Speed is constant‚ velocity is not. Centripetal Acceleration‚ – acceleration that maintains the object along a circular path directed towards the center. Also called as radial acceleration

ATOMIC PHYSICS The nuclear atom All matter is made up of atoms which consist of a central nucleus‚ surrounded by electrons. Inside the nucleus are protons and neutrons. Particle Relative mass Charge Location Proton 1840 + Nucleus Neutron 1840 0 Nucleus Electron 1 - Outside nucleus Proton or atomic number (Z) This is the total number of protons in the nucleus of an atom. Nucleon or mass number (A) This is the total number of protons and neutrons in the nucleus of an atom. Note: a nucleon

This is not very accurate data because there is air in the room too. And the doll on the parachute is always moving around when it drop‚ so the distance of the parachute is not very accurate. Conclusion: In this lab‚ we have changed our IV and DV after we done the first time lab because we can’t measure the air

Plasma Complexity! Plasma is said to a substance similar to gas in which a certain portion of the particles are ionized. The basic premise is that heating a gas dissociates its molecular bonds‚ rendering it into its constituent atoms. Further heating leads ionization‚ turning it into plasma: containing charged particles‚ positive ions and negative electrons. The presence of a non-negligible number of charge carriers makes the plasma electrically conductive so that it responds strongly to electromagnetic
