Física Experimental (IST)

Física Experimental (IST)

Curso que assenta na construção de experiências a partir de material corrente e na utilização do e-lab (laboratório acessível remotamente). Neste curso os participantes irão adquirir conhecimentos de análise de dados e tratamentos dos erros experimentais associados, bem como técnicas numéricas de ajuste de funções aos modelos teóricos que descrevem as experiências propostas.

Será dada ênfase a este último tópico e em particular serão utilizadas experiências que exemplifiquem casos sucessivamente mais complexos de ajustes numéricos de funções. No entanto, será preterido um formalismo matemático em prol do uso de técnicas computacionais disponíveis em folhas de cálculo, como o MSExcel ou on-line como o Fitteia. Em particular pretende-se que o participante desenvolva competências de análise de dados experimentais e definição de critérios para a aceitação do modelo teórico proposto.

Neste curso usaremos experiências básicas mas que refletem a riqueza da física e química:

  • Pêndulo simples e física do globo

Pré-requisitos
Este curso é indicado para uma introdução a técnicas laboratoriais, em particular à física e química. Nesse sentido, o conhecimento de termos e conceitos básicos destas áreas é uma mais valia.
O requisito principal será o conhecimento matemático de funções e suas derivadas.
Material necessário:
Para realizar o curso é necessário dispor de um computador com acesso à Internet, com a instalação previa de:

  • plataforma Java
  • MSExcel ou outra folha de calculo
  • VLC ou outro visualizador de vídeo

Sendo este curso de índole experimental também será necessário preparar, previamente ao início do curso, um conjunto de materiais simples, listados de seguida:
Pêndulo simples

  • Bola saltitante ou outra massa equivalente;
  • Cordel fino de 2m e um clip de ferro;
  • Régua/fita métrica;
  • Cronómetro;
  • Batente/limitador de curso.

Chemical reactions underpin the production of pretty much everything in our modern world. But, what is the driving force behind reactions? Why do some reactions occur over geological time scales whilst others are so fast that we need femtosecond-pulsed lasers to study them? Ultimately, what is going on at the atomic level? Discover the answers to such fundamental questions and more on this course in introductory physical chemistry.

Chemical Engineering Thermodynamics 2 (Coursera)

An appreciation of thermodynamics is required to become a chemical and biomolecular engineer. Thermodynamics can assess the viability of a process and is one of the curriculum's most essential topics. The principles are utilized in following engineering courses (kinetics, mass transfer, design, materials) and are applicable to numerous engineering disciplines. The increased emphasis on energy usage and transformation as a result of rising demand, diminishing supply, and global warming necessitates that the engineers who will tackle these issues have a firm grasp of thermodynamics.

Understanding Modern Physics I: Relativity and Cosmology (Coursera)

The 20th century was known as the century of physics. In the past 120 years, concepts such as space, time, energy, entropy and particles were understood to much deeper levels. New paradigms of thinking such as relativity and quantum mechanics emerged. This course is the first course in the Understanding Modern Physics series, which covers an introduction to special relativity, general relativity and cosmology.

Flight mechanics - The basis (Coursera)

More than one century after the Wright brothers' first flight, the flight still defy our intuition. You will learn here how to name the different parts of the airplane and how to describe and quantify its geometry. For that, we need now to share a precise vocabulary to describe the airplane's movement and attitude in space, and a refresher on basic general mechanic principles. You will remind how Newton's 2nd law allows you to determine what force must be applied on an apple - or on an airplane, to modify the magnitude and direction of its speed.

Mechanics: Motion, Forces, Energy and Gravity, from Particles to Planets (Coursera)

Most of the phenomena in the world around you are, at the fundamental level, based on physics, and much of physics is based on mechanics. Mechanics begins by quantifying motion, and then explaining it in terms of forces, energy and momentum. This allows us to analyse the operation of many familiar phenomena around us, but also the mechanics of planets, stars and galaxies.

The first MOOC “Photovoltaic solar energy” is a general presentation of the solar photovoltaics technologies in the global energetic context, without extensive details. In particular the description of the solar cell operation is restricted to the ideal case. In contrast this second MOOC allows a deep understanding of the properties of solar cells based on crystalline semiconductors.

AstroTech: The Science and Technology behind Astronomical Discovery (Coursera)

Modern astronomy has made some astonishing discoveries - how stars burn and how black holes form; galaxies from the edge of the universe and killer rocks right next door; where the elements come from and how the expanding universe is accelerating. But how do we know all that? The truth is that astronomy would be impossible without technology, and every advance in astronomy is really an advance in technology. But the technology by itself is not enough. We have to apply it critically with a knowledge of physics to unlock the secrets of the Universe.
