MALIEK’S WORK ( Click here and download a pdf with your work for today Monday ).
You already know that forces are measured in NEWTONS. But today we are using the appropriate device to measure forces, like weight, using the DYNAMOMETER. It is like a spring with a scale given in newtons in which we can measure different objects’ weights. The more the object weights the more the spring inside stretches and more newtons are given onto the scale.
1.13.a.1 Data table for dynamometers. ( 10 points ).
Students use different kinds of dynamometers to weight several different amount of objects with different weights. They have dynamometers in grams, in newtons and in kilograms at their reach. Once they weight the same objects as much in grams as in newtons they take notes about them at the paper given. They get used to read the different scales dynamometers show.

MALIEK’S WORK (Click here and download a pdf with your work for today Wednesday ).
Please Maliek, read the pdf with the text about Hooke’s law and do a little summarize of it at your workbook. After that look up for information about who Robert Hooke was and did because he is the scientist who did the Hooke’s law in 1660.
+ INFORMATION ABOUT HOOKE’S LAW AND DYNAMOMETERS : Copy the following information about Hooke’s law given in PICTURE 1 at your workbook :
1.13.a.4 WHAT A DYNAMOMETER IS. ( 5 points ).
1.15 We work today in the computer room 217.
Follow the instructions given by your teacher in order to do your work at the computer. ( 20 points ).
* First of all copy the following learning targets at your workbook in order to understand what you are going to learn today in class :
LEARNING TARGETS FOR TODAY’S LESSON.
* Consult the following links in order to answer the following QUESTIONS :
LINK 4 ( Nice Hooke’s law simulator, try it!! )
( At this simulator you can try with different values of the spring constant K in order to make the spring thicker or thinner and make it stronger or weaker and check how much it stretches when a force is applied ).
- If you have enough more time do a powerpoint presentation telling about Hooke’s Law, what it is, what it represents, what it talks about springs, about the Hooke’s law graph, and talking something about who Robert Hooke was. A general presentation about the Hooke’s law issue.

VECTORIAL AND ESCALAR MAGNITUDES.
* Activity 1.11 : Vectorial and scalar magnitudes. ( 9/8/17 Friday )
1.11.a Studying scalar and vectorial magnitudes : ( 10 points ).
Magnitude is every property that can be messured, like speed, weight, acceleration, mass, density, electrical conductivity, velocity, force, capacity, volum, etc.
- Some magnitude only need a number or quantity to be defined like the capacity and volum a bottle has, like 30 oz, or 2 liters, etc.
- Another magnitudes, like forces, velocity, etc, need both a number and a direction or vector, because they need to be determined by a direction. We must indicate in which direction, using an arrow, it goes. For instance the velocity and acceleracion a car is having need a vector, but the speed does not because speed is only a number.
1.11.b Speed and velocity ( 5 points ) : ( 9/11/17 Monday )
1.11.b.1 Reviewing test about vectorial and scalar magnitudes. ( 5 points ).

1.11.b.2 Finishing drawings from yesterday. Test-learning activity with the whole group about forces and vectors. ( 5 points ).
( 9/13/17 Wednesday )
1.11.b.3 - Difference between speed ( scalar magnitude ) and velocity , force ( vectorial magnitudes ).
Copy the following outline in your workbook in order to check the difference between the scalar variable of speed and the vectorial one of velocity :
Outline picture from whiteboard about speed and velocity.
Speed has no direction while velocity does. For example, if I say that I’m running at 10 mph, I have given you my speed. If I say that I’m running 10 mph north, then I have given you my velocity.
The short answer is that velocity is the speed with a direction, while speed does not have a direction. Speed is a scalar quantity -- it is the magnitude of the velocity. Speed is measured in units of distance divided by time, e.g. miles per hour, feet per second, meters per second, etc.

1.11.b.3.2 Make the following drawings at your workbook and indicate the forces the cars are doing, their vectors, directions, speed and velocities’ vectors : ( 10 points ).
TRUE OR FALSE ABOUT FORCES AND SPEED ? : ( 5 points each ).
Pointing out the parts of a force activity.
1.11.c Forces, vectorial magnitude. Parts of a force ( 10 points ).
1.11.c.1 Therefore we can say that velocity is a vectorial magnitude and speed is a scalar magnitude. The same about forces, when a force is indicated a vector (arrow) is needed as well as the number or value, so a force is a vectorial magnitude.
( 5 points )
FORCES ARE MEASURED IN NEWTONS, THAT IS THE UNIT OF A FORCE, AND IT IS MEASURED WITH A DYNAMOMETER.
A dynamometer or "dyno" for short, is a device for measuring forces.
