![]() ![]() But they are no variables, they are constants! Once they give them to you/you find them/decide them it is donde: they are constants, they do not change, they value is the same until you finish the problem/stand in front of other movement in other class, in other country. If no one hands them to you, you may be able to find them or asign them the values you want to asign them. If your are lucky, you might be given the value of those constants. What you have to do is to find (or sometimes even decide) the value of those constants, the blue ones ( x o, vy t o ). TO ASSEMBLE A KINETIC EQUATION MEANS TO REPLACE THE CONSTANTS If the variables don´t show up you are screwed, there is no kinetic equation. The variables (the red ones) are not to be touched, if you touch them, you may break it and well, it is broken, you can´t use it anymore. The blue ones are the constants, the red ones, the variables. Look, so you can distinguish them easily I´ll copy the equation again, this time, in technicolor:: In addition to the math symbols, the kinetic equations have twoconstant components ( x o, v and t o) and variables ( x and t). Once you know that, you look for the model that adapts to that movement.įor example, let´s suppose we have a MRU, you look for the model and you find it, is is this one: It is very easy: first you have to know wich kind of movement appears in the problem, for example: MRU, MRUV or whatever movement is described. If there is more than one movement, well, different equations for them all.īut you are not going to receive the equation, YOU have to ASSEMBLE it. To solve the quesitons of the kinematic, the main tool we use is the kinematic equation, wich describes the movement that appears in a problem.
