Uniform Rectilinear Motion Concepts

This video tutorial covers the concept of Movimiento Rectilíneo Uniforme (MRU), where a body moves in a straight line with constant velocity, resulting in equal distances covered in equal time intervals. The video explains that in MRU, acceleration is zero, and the resultant force is also zero. Graphical representations of distance-time and velocity-time are discussed, showing constant velocity and proportionality between distance and time. The formula for MRU is introduced, along with unit conversions for distance, time, and velocity. The video concludes with a preview of upcoming exercises on MRU.
