Forces and measuraments.

* Activity 1.13 : Force’s units and measuraments. ( 9/18/17 Monday )

1.13.a Measuring forces with a dynamometer : ( 10 points ).

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.

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.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.

1.11.b.3.1 Reviewing activity 1 about drawing vectors and forces. ( 5 points ).

Reviewing activity 2 about drawing vectors and forces. ( 5 points ).

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.

( 9/14/17 Thursday )

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 ).

1. In order to learn what a Force is and the effects Forces can produce we develope the ACTIVITY 1.1.

1.1.a In this activity you are going to follow your teacher instructions in order to manipulate the following materials : Two pieces of paper, a pen, marble, your own hands.

In pairs, with those objects, ask your partner what you must do to get the following effects :

- Folding.

- Deformation, loss of shape.

- Breaking.

- Heating.

- Change of velocity, turn, spin, motion.

1.1.b Draw a chart at your notebook in which you write the effects a force can do.

Besides the effect write a little description of an example of you have done in order to get that effect.

Draw a chart like this : CHART.

1.1.c We should try now to explain what a force is, what it is not an easy task.

Talk in a voice level 2 with your classmate about how to explain what a force is. Try to explain to each other without using the Word FORCE.

1.1.d Once you have talked for a while, and when your teacher tells you, watch the following video and after watching it, talk with your partner again trying to explain now with other words what you thing a force is.

VIDEO 1.1.d Forces and its effects.

After watching the video and talking with your classmate, write a proper definition at your notebook about what you think a force is. You can use an example (situation) in order to explain it.

1.1.e > Once you have written your own definition about what a force is, copy the following description of a force :

A Force is :

a) A force is a push or pull upon an object resulting from the object’s interaction with another object.

b) Whenever there is an interaction between two objects, there is a force upon each of the objects.

c) When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction.
