Physics is an experimental science

rectilinear motion

physics allows us to approach the reality of the past of our universe, saw the video that shows how has been the impact of a meteorite with the Earth, maybe the collision of stars that hiso wiped out the dinosaurs, these behemoths and huge animals that populated the earth.

Physics also allows us to approach the reality of our future cosmos. The future of the universe. The future of our planet. Some raise an apocalyptic future where the human race perish ... but we prefer to think that "always better times" , not only for our universe, so for us as a species ...

Understanding the complex movement This Megalocosmos is the goal of the physical sciences, but we must start with small steps towards this understanding. To do this we begin with the simplest of movements: the rectilinear movement (MR ).

Consider the following concept map:

http://es.wikiversity.org/wiki/El_movimiento_rectilineo_ (Grupo_2)

Solve your notebook the following concerns:

• What new concepts are related in the conceptual map Rectilinear Movement?
• indicated on the website listed some key definitions. Write in your notebook those definitions that are new to you.
• Section "key ideas" is an explanation related to the concept map. Copy these key ideas. What would annex to these key ideas? Which of the concepts are too few, the author of the concept map, and therefore, you, you completed?
• What do you understand about Galileo, in the "list of key issues?
• explains how to understand the concept map that appears on this site.

ANALYSIS OF MOVEMENT OF A STRAIGHT PELLET

Answer in your notebook:

• explains in detail what the video shows
• " What tools used girls for observation, hypothesis testing approach and findings in relation to the movement of the pellet?
Why
• which journeys are made by observation and measurement of time?
• How many times is timed for each of the road? Write the results achieved by girls.
• The pellet always released from the same height in order to always move with the same speed. How do I calculate the speed of the pellet in each case?
• If the distance the shot, and the speed is the same, because the results obtained by the students are not equal for each of the spaces or distance the pellet?
• The following table shows the values \u200b\u200bof X (sod) vs T (X v Time):

· On a sheet of graph paper draw the graph of X (displacement Δs) v t (Dt) .

· What variable is located on the horizontal axis and what variable is located on the vertical axis? Explains why,

· What type of diagram are obtained? What kind of mathematical relationship exists between displacement and distance?

· Calculate the slope of the line. What indicates this value?, What are the units of the slope?

· Find an equation that describes the displacement as a function of time for the pellet.

· Starting from X vs T graph, draw the graph of V vs T for the movement of the pellet. ( use graph paper).

· Use the graph of VV s T to calculate the distance traveled by the pellet. Compare your results with those obtained by students in the video. (Use graph paper).

· Write your conclusions and show their work to teaching.

Look, but mostly listen carefully, learn to use the fundamental equation of uniform linear motion with a magic triangle!

· Explain to your teacher as you understand the magic triangle that shows then a professor (double ss):

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.

4. Login here: http://www.educaplus.org/movi/2_2vectorpos.html

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)

5. Login here: http://www.educaplus.org/movi/2_2vectorpos.html

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.

    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.
