What is Uniform Rectilinear Motion?

Characteristics of Uniform Rectilinear Motion

  • The characteristics of uniform rectilinear motion include a constant acceleration of zero, meaning that the initial, average, and instantaneous velocities remain unchanged.
  • A body exhibits uniform rectilinear motion when its trajectory is a straight line and its speed remains constant.

Experiment Demonstration

  • The video introduces an experiment to demonstrate uniform rectilinear motion using dominoes, a measuring tape, and a stopwatch. Each domino should be spaced three centimeters apart.
  • In slow motion, it is observed that 28 dominoes fall in 14 seconds. This results in each domino falling in 0.05 seconds, calculated by dividing the total time by the number of dominoes (14/28 = 0.05).

Further Calculations

  • The experiment is repeated with half the number of dominoes (14). According to calculations, these should take approximately 0.7 seconds to fall.
Video description

En este vídeo mis compañeras y yo os explicamos mediante un experimento con fichas de dominó el concepto de Movimiento Rectilíneo Uniforme. Así junto con los demás vídeos y esta demostración la teoría del MRU queda clara.
