A Natural Philosophy

Reflect a little

Does the movement means life or death?

How many times has this happened in the history of our planet?

The Movement is life, we run, we play we laugh, we move on this planet that excels in beauty. Rivers, waters, seas, winds, the earth itself is moving.

Everything moves: inside our blood in our veins and arteries move with a certain speed, the very activity of the spermatozoon in search of an egg for fertilization is a competition which involved action again the kinematic concept of speed.

The "run run" daily tasks, school, the struggle for life, they also imply distance or space walks, travel, trajectories, speeds and speed, competition for living!

Breathe, feed, love and even the most insignificant details of our existence is about movement, life ... ... ...

But there are movements that involve annihilation, destruction, death ... discussed this video with your peer group and answer the following questions:

1. If everything is moving then studied physics at all?

2. Why study physics? This has allowed us to simulate in a video, a possible future event, or perhaps an event that the planet has suffered several times, and that many fans recall some apocalyptic beliefs.

3. movement, is life is death?

Well, kinematics not only do trolleys or other bodies in motion, it also invites us to reflect on the great realities of our existence, so perhaps its principles was called natural philosophy ... But always better times ...

presents conclusions on the reflection to your teacher. Consider the two videos.

The Kinematics

VECTOR POSITION AND REFERENCE SYSTEM

• The position of a body in a certain moment we have represented through a vector.

• when moving body occupies various positions, the set of points where the body moves is the same path. The path may be rectilinear or curvilinear.

• To locate the position vector and coordinates requires a reference system.

• The reference system can be one-dimensional (straight line), two-dimensional (Cartesian) or three (Geospace).

• The following activity allows us to locate positions in different frames of reference we mentioned:

  • Login to: http://www.educaplus.org/movi/2_1pospunto.html

1. location positions in one dimension:

• Imagine that we have a body that moves in a straight line, ie makes a move in one dimension. To determine your position need only indicate the distance from the origin is. Observed in the previous applet body position can be positive or negative as found on the right or left of the origin respectively.

• in the applet above represents the following:

• P (-2.8)

• P (1.7)

• P (0)

2. The location of the position vector in two dimensions requires the use of two coordinates.

3. The use of two coordinates is possible with a Cartesian or a polar coordinate plane. Practice with both systems.

5. In the two-dimensional applet, select the Cartesian coordinates and represents the following positions:

• (-3, -3)

• (-1.3, 2)

• (0, 2.7)

• (3.5 , 1)

• (0.5, 3.5)

6. select polar coordinates and represents the following positions:

• ( 3, 120 °)

• (2, 45 °)

• (3, -90 °)

• (2, 30 °)

• (1, 90 °)

6. prove now dial positions in terms of three dimensions.

7. Login here: http://www.educaplus.org/movi/2_1pospunto.html and find the reference system in 3 dimensions.

8. Test varying the values \u200b\u200bof x, y, and z is the position (96, 100, 50).

9. You try to rotate the reference system using the click to view different perspectives held the position vector.

10. Try again find the position: (-62, 110, -85).

11. Use the sharp click of the mouse to get different perspectives previous position.

12. Questions:

• How is the type of trajectories for movements in one dimension?

• How is the type of trajectories for movements in two dimensions?

• How is the type of trajectories for movements in three dimensions?

• Enter the following address and produces a conceptual map on the topic of careers: http://www.educaplus.org/movi/2_3trayectoria.html

• Consultation on lines, straight, curved, flat and curved non-planar to enrich your conceptual map.

13. In relation to the distance and displacement:

    1. we discussed in class X vs T plots and calculated distances and displacements.

    2. displacement and distance Are scalar or vector quantities? Explain your reasons.

    3. Performs the activity of this page: http://www.educaplus.org/movi/2_4distancia.html

    4. must draw several paths and differentiate the value of the distance and the offset.

    5. What requirements must the path to obtain the same numeric value in the distance and displacement?

    6. What requirements must meet the trajectory for the offset value is zero?

14. In connection with the quickness and speed:

    1. have calculated already in class speed and quickness in graphics Type X Vs T.

    2. The quickness and speed, are scalar quantities or vector? Explain your answer.

    3. Login to the site; http://www.educaplus.org/movi/2_5velocidad.html

    4. must carry out the activities that arise in the previous page.

    5. Makes a concept map that summarizes the activities and concepts raised in the previous page of item 14 _ 5.

    6. your teacher presents the findings on this activity.
