UNIT 1 :    MOTION

SECTION 2 , LESSON 1,  MRUA.
( Moviment rectilini uniformement accelerat, Constant or uniform acceleration motion ).

-  Converting units with conversion factors review.

( Do the unit changes suggested in class ).
( Corrections of the exercises suggested ).

- Read the following description about what’s the difference between velocity and acceleration, check also the corresponding equations and try to summarize the main issues at your notebook. Write it down if you agree with it too  :

The difference between velocity and acceleration can be drawn clearly on the following grounds:

The velocity of an object refers to the speed in a specific direction.
Velocity is nothing but the rate of change of displacement. On the other hand, acceleration is the rate of change of velocity  with respect to time.

PER CANVIAR LES UNITATS DE LA DENSITAT.

- Activitat 1:        Video : què és la densitat ?.

b)  Ara aplica el que has après al següent projecte. Fes grup
amb dos o tres companys més de classe per fer-lo junts :

Consulta aquesta FOTO del teu profe on trobaràs la massa
i el volum d’una molécula d’aigua.  Una vegada tingueu
els valors de massa i volum, passeu la massa a grams i
el volum a centímetres cúbics i calculeu la densitat
d’aquesta molécula en g/cm3.  Després, amb els factors
de conversió que haveu estudiat en l’apartat a), passeu
el valor de la densitat de la molécula a Kg/m3.

c)  Per entregar el treball del projecte, feu una mena d’informe
en el que aparegui el dibuix de la molécula i el nombre dels
àtoms que la formen i els càlculs fets i factors de conversió
realitzats i al final el resultat obtingut de la densitat en kg/m3.

- Aquí pots consultar información important sobre la molécula d’aigua.

- Aquí tens l’activitat resolta perquè puguis comprovar  els càlculs i
veure com s’han fet els factors de conversió i els resultats obtinguts
per a la densitat en g/cm3  i  en kg/m3.

- Activitat 2 :   L’informe científic.

- Consulta aquest LINK i mira les parts que ha de tenir un informe.

Després de fer la pràctica que t’indicarà el professor, fes l’informe
corresponent. Hauràs de calcular la densitat d’un objecte en g/ml
i en g/cm3 i en kg/m3 que et donarà el professor.  Una vegada acabada
la pràctica hauràs de presentar un informe de la mateixa tal com has
vist al link que se t’ha proporcionat i com també t’explicarà el professor.

Aquí tens un video de la pràctica que s’ha fet perquè tinguis un

## 4ESO FQ English 2018-2019. Unit 1 MOTION. Article 3.

Publicado: 24/10/2018 02:47 por easyfisquim en 4ESO FQ (10th gr Science) 2018-2019

UNIT 1 :    MOTION    ( Lesson 3)

SECTION 3 , LESSON 1 ( Gravity and free falling motion).

(  Free falling object motion or dropping motion  ,  circular motion).

-  First of all let’s watch a video about what free fall vertical motion is.

*After watching that video, what do you think are the most important issues
we have to have on account when approaching and facing a free fall motion
exercise or situation?.
SCAFF 7d :  Fill out the chart .

+Next you’ll find the chart filled in, to check it and correct your answers and
the way to fill it out. It Will be posted once we achieve yet the activity in class.

-  Link 1:  Free falling motion introduction website.  Motion’s details and gravity.
-  Link 2:  Read here what GRAVITY is and what gravity’s acceleration is.

-  Link 3:  This website has really remarkable information, solved exercises,

- Let’s watch this video about how to solve a one dimensión MRUA free fall motion
( upwards thrown object motion ) exercise and after watching it
we’re gonna work it out again by ourselves.
This would be the wording about the problem this teacher is figuring out :

A kid is placed 20m high from the ground and throws an object upwards with a
velocity of 15m/s. Find out the time the object takes to fall and  hit the ground
and the final velocity it takes just before hitting the ground.

- Let’s just do the same exersice as the previous one above but this time the kid
is throwing the object from the same high at the same speed but to the down
direction, to hit the ground directly.  Watch the video now in class or at home
(follow your teacher’s directions) and we do it later on the board.

SCAFF 8 :
-  Pic Activity   :    Check this pic your teacher’s taken showing the equations
between MRUA (uarm) and free falling motion. Write on your
notebook what they both have in common and why they have
something different. You’ll need to read the links 1, 2 and 3 from
above of this lesson to know well what free falling motion is

-  At this point we do exercises 11 and 12 on page 27 from your student’s book.

-  Let’s check : Upward thrown object motion exercise example 8 on page 28.

-  After checking the example, let’s try this one!! :

A person standing on the edge of a high cliff throws a rock straight up with an initial velocity of 13.0 m/s. The rock misses the edge of the cliff as it falls back to earth. Calculate the position and velocity of the rock 1.00 s, 2.00 s, and 3.00 s after it is thrown, neglecting the effects of air resistance.
sol : within LINK 3 above

- Watch the following pic about Hulk, Spiderman and gravity and have a small
talk in groups or in pairs to give your opinion about the studied motions involved.

-  Now we do exercises 13, 14 and 15 on page 28 from your book.

solutions :   ex 13     ,     ex 14     ,     ex 15

-  Link  : Link from the last school years with free falling motion exercises and
examples and videos helping solving this kind of problems.

-  Link :  Free fall motion complex problem to solve, and solution provided.

*  Take a look to this cartoon and discuss what’s involved in it

- To review the lesson you can try doing the following exercises on page 35 from
your book. You are also given the solutions at the following links :

UNIFORM CIRCULAR MOTION.

-  Link 1a:    Uniform circular motion video to start.

-  Link 1b:    Visualize circular motion agains constant acceleration motion.

-  Link 2:    Circular motion main equation and information.

-  Link 3:    Circular motion teacher’s website with physics related to circular
motion.

-  Link 4 :     Circular motion experience 1 done by last years former students.

* Choose one of the following experiences to make:

-  Link 5a:      Uniform circular motion experience 2 to achieve.
-  Link 5b:      Uniform circular motion experience 3 to achieve.
You can also check the same experience as 5b here in 5c.

+  How to transform or convert degrees to radians and vice versa :

factors from degrees to radians and back.

- Once you’ve checked all the materials from this blog and you have already organized your 3 or 4 people group, share responsabilities among your group’s members in order to write a general outline for giving a speech later showing your contents about uniform circular motion, linear velocity, angular velocity, differences among them and conclusions. Don’t forget to give experimental data and examples to substantiate your reasons.

* If needed you can get help to collect vocabulary and structures to write your text from the quizz and all other materials provided at the blog.

- You do now exercises 16, 17 and 18 on page 30.

solutions :           ex 16 and 17               ex18

- Circular motion exercise from the blackboard .  Wording :

Some friends are skating around in circles holding by their hands in line. A girl
at the opposite end of the line is 12m far away from the center of the circle they
are spinning around. One girl’s friend is closer to the center spinning with an
angular velocity of Pi/2 rad/s and a linear velocity of 4m/s.

Find the linear velocity the girl shows at the Edge of the skating line in a certain
momento and the distance the boy is placed from the center of the circle.

*Check the solution here on these two pics :

- Make a lesson summary like this one appearing on page 31. Do it in english
language and try to use your own words.

ORAL PRESENTATION. MOTION ISSUE SPEECH.

- And now you can check on these files the steps to be followed in order to make
and design an oral presentation about one specific motion lesson issue left up
to you.  On the first file you will find some help, advises and rules to write your
presentation and some important aspects to keep in mind when you make your
speech to the audience. At the second one you are provided by information and
tips in order to assess your peers’ presentations :
