A Uniform Rectilinear Motion is a phenomenon in which three variables are put together to write a constant displacement, in a non-deformable straight line and without any type of acceleration. The MRU in acronyms (Uniform Rectilinear Motion) is one of the forms of displacement that are seen first in basic education diversifies in the field of physics, since it is the simplest of movements and its calculation depends on variables whose denotation is constant too. The Graph shows how the relationship between time and distance (expressed in meters) is increasing, while the speed remains constant over time since otherwise it would cease to be uniform and the acceleration would be present in the graph.
The formulas that are learned to calculate the Uniform Rectilinear Motion are simple, applying given variables in order to calculate by means of the clearing each one of them in relation to the other. We will explain them below:
- The distance (D) that is covered is calculated by multiplying the speed (V) which we must remember that s always constant with time (T) which carries the journey being as follows D = V * T.
- For the time (T) dividing the distance (D) between the speed (V) to obtain T = D / V.
- The speed (V) is obtained under the same rule V = D / T.
The symbology system with the clearing process is also canceled, leaving the corresponding units for each magnitude, it should always be like this, care must be taken not to present the answer of the exam with a different unit than the one established for each one, since it would not exist correspondence with data and units. The Uniform Rectilinear Motion is an ideal situation, in which there are no agents that disturb its condition, if they exist they would change the methodology to be applied, as stated by Isaac Newtonin the laws of physics that remain in force to date in the fields in which the MRU is studied and those that complement the theory. The graphical representation of the distance traveled as a function of time gives rise to a line whose slope corresponds to the speed.
