of the hoop a compass is mounted. When a direct current flows through the wires‚ a magnetic field is induced in the space surrounding the loops of wire. This magnetic flux is designated by Bi . The strength of the magnetic field induced by the current at the center of the loops of wire is given by Amperes law: Induced Bi = [pic]. where μo is the permeability of free space and has the value of 4π x 10-7 N/A2‚ N is the number of turns of wire‚ I is the current through the wire‚ and R is the

The Physics of Basketball Brittney LeBlanc Physics 122 Physics comes into play throughout our lives‚ in absolutely everything we do‚ especially in sports such as basketball. Although you do not need to be a physician to become a basketball player‚ if you understand the basic physics of basketball‚ it can be very beneficial to your game. Specifically‚ understanding the physics behind shooting‚ passing‚ and dribbling the basketball. A Canadian named‚ Dr. James Naismith‚ was instructed to create an

I. Introduction Physics is the natural science that involves the study of matter and its motion through space and time‚ along with related concepts such as energy and force. More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy. Over the last two millennia‚ physics was a part of natural philosophy along with chemistry‚ certain branches

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
