Thiscontainer could be displaced vertically in order to change the water level. We would thenmake a tuning fork vibrate above the pipe and change the water level until the resonance wasat maximum intensity.Hypothesis: The

needed to pick something that was centered on physics. At first we were looking doing something towards space or the speed of light‚ but then Karina brought up the topic of roller coasters and it stuck. It really sounded like a fun topic to cover. In this essay we will be exploring the world of roller coasters. Some of the topics we will cover will be the history‚ the principles that allow the cars to continue throughout the length of the track‚ and the physics of roller coasters. The history of rollercoasters

world. We chose physics as our topic of calculus application in real world because we believe that physics phenomenon is very common in our life. Physics is involved in many aspects of our life‚ such as driving‚ running‚ basketball‚ tennis‚ cycling‚ computers; many parts of our life involved physics. Companies such as automobile companies utilize physics to make their cars or motorcycles more aerodynamic‚ thus increase their speed. Cars are something that is closely related to physics since without

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

AIM: Finding the gravitational field strength by using a simple harmonic motion of a spring and slotted masses. INTRODUCTION: When a mass suspended from a spring is displaced‚ due to the acceleration‚ kg s-2‚ from its equilibrium and released it will oscillate up and down with a kind of motion called simple harmonic motion‚ shm. The period (T)‚ time taken to measure for one complete oscillation‚ of this motion is: m/kg =
