Tagarao, Isaiah Jeremy July 26, 2013 Tatlonghari, Patricia Anne Nicole Valena, Carmelo Miguel O. Valena, Keena Wong, Monika Yu, Princess Dianne Mei Group 8 SPECIFIC GRAVITY OF SOLIDS AND LIQUIDS Experiment No. 3 Abstract: Questions and Problems 1. Differentiate specific gravity and density. Answer: Density is the measure of the amount of mass per volume of a given substance. Density can be expressed using the equation: ρ=mv Specific Gravity is the measure

Mathematics in Rollercoasters There are several different types of math used in building and creating roller coasters. Some of them are: angles, heights, velocity, slope, gravity, rotation, and more. Below, I will be explaining some of the equations and mathematical ways of figuring them out. First there are angles, which is “the space measured in degrees between two intersecting lines or surfaces at or close to the point where they meet.” To figure them out, the engineers use machines, models,

In the 4-3 Lab, my group and I tossed a ball over a motion detector and recorded the measurements at five different points of the ball’s travel. Point A was at the beginning of its travel, right after it was thrown. Point B was about halfway up after the throw. Point C was at the highest point of the ball’s toss. Point D was at about the same height as point B, but was on the way down from Point C. Point E was right before I caught the ball at about the same height as point A, but on the way down

Physics pre-assessment research task 1. Describe de Broglie’s proposal that any kind of particle has both wave and particle properties De Broglie suggested that if light can behave as both a wave and as a photon, particles could also have dual character. He proposed that all particles had wave properties as well as particle properties. He proposed that the wavelength is inversely proportional to the momentum of the particle, now known as the de Broglie wavelength of a particle and given by,

HSC Physics Assessment Task 1 – Part B Hermann Oberth Hermann Oberth was a German Physicist who made large contributions to the field of rocketry in both the basic theory and the design of rockets. In 1922, he submitted a physics dissertation while studying at the University of Heidelberg on this subject. This paper examined mathematically the possibility for a rocket to reach escape velocity and leave the Earth’s orbit. He also supported and explained the notion that rockets could be propelled in

Aristotle (384 – 322 BC) Developed a theory that the universe was ‘geocentric’. With the Earth being the centre of the universe, with everything else orbiting it. Aristotle’s basic ideas survived for nearly 2000 years, this stood for so long due to the lack of technological advancements at such an early stage of the world’s existence. Aristarchus (310-230 BC) First astronomer to suggest that the Sun was the centre of the Universe, this known as the geocentric model. However his theory did not

Heat Transfer Conduction When we place one end of an iron rod in a fire, the other end also heats up after a while. We say heat has been conducted along the rod from the hot end. Conduction is the process by which heat is transmitted through a medium from one particle to another. The heat is transmitted from the hot to the cold end. Most metals are good thermal conductors. A metal surface feels colder than a cement surface although they are both at the same temperature. This is because e

PURPOSE Measure the acceleration of a falling object assuming that the only force acting on the object is the gravitational force. THEORY In this lab, a free fall adapter measures the time it takes for a steel ball to fall. The distance in which the ball falls will be measured. The equation, d=1/2gt² describes a body starting from rest and undergoing constant acceleration; d is the distance, g is the acceleration and t is the time. Acceleration is equal to distance doubled divided by time squared
