¿Qué es la física?La física se encarga de derivar relaciones entre cantidades para que seamos capaces de hacer predicciones. Para derivar esas relaciones tenemos que poder hacer mediciones del tamaño de las cantidades.Ejempo de una cantidad: la gravedadUna bola grande de plastilina es más pesada que una pequeña. Para cuantificar el tamaño podemos...
AceleraciónLa aceleración se define como la variación de velocidad por unidad de tiempo: Si la velocidad de un cuerpo cambia, entonces ese cuerpo tiene una aceleración, independientemente de si está incrementando o disminuyendo su velocidad. En ese sentido, la definición del término difiere de su significado en el lenguaje cotidiano, donde la aceleración...
Definiendo cantidadesSi buscas la palabra 'distancia' en un diccionario encontrarás que tiene muchos significados distintos. Lo mismo ocurre con 'desplazamiento'. En física, las palabras tienen un único significado, y este está claramente especificado en la definición de la palabra. Es importante recordar estas definiciones para que las cantidades...
Movimiento sometido a la gravedadCuando una pelota se lanza verticalmente, esta viaja hacia arriba mientras su aceleración disminuye, luego se para momentáneamente y, finalmente baja de nuevo. Si tomamos la dirección hacia 'arriba' como positiva, la aceleración de la pelota es negativa tanto en el movimiento hacia arriba como en el movimiento hacia abajo. Si medimos...
In this activity on Measurements and Uncertainties, you will be introduced to measuring with a Vernier caliper, estimate uncertainty, practise the (max - min)/2 method, distinguish random and systematic errors, process data with Excel, draw graphs with Logger Pro, understand the benefits of linearisation in identifying relationships and calculate the uncertainty in gradients.
Need to know
Topics: measurement and uncertainty n2k
Number of flashcards: 1
This topic is the first in the Subject Guide, and there are some aspects that will need to be tackled before your students can commence other physical concepts. For students who have not studied physics recently or ever before, they should become familiar with taking measurements, identifying the uncertainties associated with data and learn the techniques for adding vectors. In this section of the website, you will also find a 'Mini Investigation'. This can be an engaging way to introduce students to the IA, perhaps after completing Mechanics.
A well planned site with lots of informations in Physics!
I consider Chris Hamper's InThinking page for IB Physics to be an indispensable resource for the course. Whether you use his textbook or not the IA section alone is worth the subscription cost.
I am very pleased with the website and the material. Love the animated multiple choice test questions. That is a great way to ask questions and cannot be accomplished with questions on paper. Also, the labs are very good and the suggestions are very...

IA reflections 2021I'm not much of a tracker expert but maybe it's something to do with the video frame rate, try recording with a lower rate.

IA reflections 2021Hello Chris, a few years ago when i was teaching IB Physics in Papua New Guinea, you recommended using Tracker for Video Analysis to investigate Mechanics. My students used it very successfully for class experiments and for IA work. I have...

MCQs: Measurement and UncertaintiesI’m assuming that the end is used as the zero. If this is the case all measurements will be inaccurate but precise. If you subtracted the missing bit you would be accurate and precise

MCQs: Measurement and UncertaintiesOne of my students is arguing with an answer to a given question, "The end of a ruler is broken, this will affect:". They believe the answer is "neither accuracy or precision" and no matter the scenario I provide for reflection, the student...

Mind-flash The complete coreHi Althea; They should run on the page but you shouldn't be able to access the original Google slides file without me sharing it with you. I am keen for them to be used but not copied :-)

Light from starsThanks for pointing this out. It was probably flash or java and won't run anymore anyway. I'll see if I can make a substitute in GeoGebra..

Was the SL paper 2 too difficult?Hi Chris, I guess the 2022 exam marking protocols is an unknown quantity atm. eg IA sample or marking? Additionally, the exam of 2022 class has accumulated greater learning turmoil than any previous group so far so wonder if at all this will...

Was the SL paper 2 too difficult?Hi Denis; Yes, a bit of a mess. The point you mention about different examiners marking IA's is a good one, it adds another layer on uncertainty to something with large random errors already.
