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

Test 01 - Introduction Receptor cells use chemical transmitters to communicate with relay cells or afferent nerve fibers. In all sensory systems‚ accessory structures modify‚ in some way‚ the stimulus going to the receptor surface. Receptors are electrically polarized cells and therefore have a resting membrane potential. Stimuli produce‚ in the appropriate receptors‚ a change in the electrical properties that is known as the receptor or generator potential. The two ways in which sensory stimuli

Year 11 Preliminary Assignment #2 – Physics Electricity in the Home Aim: Will the current (Amps) affect the time it takes for a slot car to complete a lap of the track? Planning the investigation: 1. What do you know about the topic from personal experience? From playing with slot cars and building tracks even before I embarked on the physics course‚ I’d always realised the relationship between the trigger and the speed of the cars. In the investigation‚ I hope to use a more scientific method

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

Theory CONDUCTORS‚ INSULATORS AND CONDUCTIVITY Conduction of electricity in electric circuits takes place due to the presence of excess electrons in materials called conductors. Electrons move in the direction in which the potential has been applied. The ability of a conductor to conduct electricity is directly proportional to the material’s area of cross section and inversely proportional to its length. Where‚ G is conductance σ is conductivity A is area of cross section
