the kinematics is the branch of physics that studies the movements regardless
causes that produce it.
rectiriño movements:
a cell phone that has a motion rectiriño when its trajectory is a straight line.
uniform motion:
a cell phone has a motion uniform when equal distances runs to equal time.
MRU (Motion rectiriño uniform)
a cell phone is equipped with MRU when its trajectory is a straight line and covers equal distances in equal times
speed:
speed is defined as the ratio between the distance traveled and time spent in travel
speed = distance / time
v = d / t
laws MRU:
first law: all the movement speed remains costante
second law: the distances covered are directly proportional to the times
