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 summer vacations immediately after Class X are a great opportunity for the students to race ahead of other students in the competitive world of IITJEE‚ where less than 2% students get selected every year for the prestigious institutes. Some students get governed completely by the emphasis laid by the teachers of the school in which they

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

Misconceptions 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

Dancers do not often understand the physics and mathematics describing their movements‚ but they know how to execute them with grace. If ballerinas were not able to feel physics‚ they would fall over. Legs‚ arms and head are oscillating as they turn– moving back and forth in seemingly separate patterns. For dancers‚ everything must move in separate patterns‚ yet at the same time‚ move at the same rhythm. This presentation introduces the history‚ mathematics‚ and physics behind ballet.

Introduction Background Theory The usual equation for measuring electric current flowing through a series is I = V/R. The current flowing in a series is affected by the voltage and the resistor that is also creating the series. Electric current is a flow of electric charge through a conductive medium. These charge is in a form of moving electrons in a wire. The SI unit for electric current is ampere (A) and can be measured by using a device called ammeter. Change in temperature can change
