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
Experimental methods predict time, distance and speed in the following experiment students analyze a rectilinear motion of a shot in a lane moving cash:

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?
- 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):

fun knowing a new language, but especially physical learning ...
