The physics of scuba diving Imagine swimming in the underwater world with all the creatures and all the beauty it holds. It is an amazing feeling to swim over coral reefs and see all the sea life up close and personal. So many scuba divers all over the world share a passion to scuba dive. Scuba diving has been a worldwide endeavor for centuries (1). Persian divers were making goggles for diving around 1300. A British engineer invented the air pump in 1771 and in 1772 a Frenchman tried inventing

The Physics of Braking Systems By James Walker‚ Jr. of scR motorsports Copyright © 2005 StopTech LLC Author’s disclaimer: mechanical systems operating in the physical world are neither 100% efficient nor are they capable of instantaneous changes in state. Consequently‚ the equations and relationships presented herein are approximations of these braking system components as best as we understand their mechanizations and physical attributes. Where appropriate‚ several examples of limiting conditions

through a more advanced explanation. Roller coaster rides involve a great deal of physics. The ride often begins with a chain and motor which exerts a force on the train of cars to lift the train to the top of a tall hill. Once the cars are lifted to the top of the hill‚ gravity takes over and the rest of the ride works on energy transformation. There is no motor or engine that takes a train around the track. The law of physics is basically the engine of the train. At the top of the hill‚ the cars possess

of Physics One of the misconceptions in physics is about Newtons laws. It says that friction can’t act in the direction of motion. This is wrong because friction can act in the same direction as motion simply because a car on a road is traveling in one direction. The friction on the tires causes it to slow down over a distance along with some air resistance. This proves that friction can act in the same direction as motion A misconception in physics is that the moon is not in free fall. This

force of gravity. - Surfers rely on weather conditions‚ their equipment‚ safety‚ and their techniques. - Low tide waves are faster‚ stronger‚ and tend to close-out - High tide waves are slower‚ and lose force. • Surfing has a wide background of physics • The amplitude in a wave grows as energy is added to it‚ and it shrinks when energy is subtracted from it. - The speed of the wave‚ and the buoyancy of the board is what keeps the ability to ride the wave and maintain speed. - When you are surfing

Sakib Khan Electric Eels – Physics The animal that is usually known as electric eel is in fact not really an eel but a freshwater species related more to the carp family or catfish family. These unique freshwater predators got their name from the immense electrical charge that they can easily generate to stun or even kill their preys and dissuade predators. Electric eels can grow extremely large which usually can reach as high as 8 foot long and weigh a great amount of 45lbs. In addition to this

PHYSICS‚TECHNOLOGY AND SOCIETY. Technology and society or technology and culture refers to cyclical co-dependence‚ co-influence‚ co-production of technology and society upon the other (technology upon culture‚ and vice-versa). This synergistic relationship occurred from the dawn of humankind‚ with the invention of simple tools and continues into modern technologies such as the printing press and computers. The academic discipline studying the impacts of science‚ technology‚ and society and vice versa

Black Hole A Black hole is a place in space where the gravity is so strong that nothing can escape it pull. Cyclotron A type of particle accelerator that was created first in the 1930’s. It was made of two Dshaped cavities in a constant magnetic field. Dark Matter A form of matter that is not like ordinary
