8.2 The World Communicates The wave model can be used to explain how current technologies transfer information. Describe the energy transformations required in one of the following: * Mobile Telephone Mobile telephones have built in microphones that changes sound waves ib Describe waves as a transfer of energy disturbance that may occur in one‚ two or three dimensions‚ depending on the nature of the wave and the medium Identify that mechanical waves require a medium for propagation

For my topic I chose to explain some of the physics involved in the sport of soccer. I chose soccer because I have played it my whole life and it is one of my favorite sports. I thought it would be interesting to learn about some of the physics involved in something that I do almost everyday and has been a big part of my life for as long as I can remember. My poster depicts the physics involved in kicking‚ the ball rolling across the field‚ and bending the ball. Kicking a soccer ball involves transferring

In this scene‚ the soccer ball was kicked by a player with a tremendous force. The Lightning hand Goalie (Forth Brother) stops the ball‚ but fly back because of the reaction force.This scene is an example of bad physics because it is unrealistic that a human can actually take off/fly after been hit by a soccer ball. Let us assume the following:-A soccer ball is usually weight 15 pounds = 0.4kg in Fifa games -We can’t simply calculate the velocity of the ball that the guy kicked in the movie. So

label the technologies on the photograph ii) Investigate three different technologies that have been implemented in cars or along roads to avoid or reduce the effect of collisions. In your investigation explain how the technology works in terms of physics laws and theories. 1. Crumple zone The purpose of a crumple zone is to increase the amount of time it takes for a car to come to a stop after being hit by an object. Crumple zones cause the force to be spread out over a long period of

Abstract Dreamworld‚ located in the Gold Coast‚ Australia‚ draws in hundreds of visitors everyday due to its extreme thrill rides and various attractions. Multiple thrill rides at the park have been researched and experimented upon‚ to evaluate the physics of the ride. The Tower of Terror II is one of the rides that has been looked upon and tested on. The Tower of Terror II is an L-shaped ride‚ the ride consists of a 6000kg cart (7000kg with the maximum 14 passengers) that travels horizontally across

The physics concepts that were illustrated in our egg drop project were momentum and energy. In the project‚ we saw how momentum increases as a normal egg without anything to slow it down would crack. That was because the longer that the egg fell‚ the more momentum the egg gains. We also saw that by adding resistance during the fall‚ such as a plastic bag “parachute”‚ would slow down the egg enough so that it would not crack when it reached impact with the ground. The other concept that was discussed
