Instantaneous and average speed with Cobra SMARTsense

Article no: P1003769

Principle
A body experiences a constant acceleration parallel to the path of an inclined path due to the component of gravity acting on it. Therefore the laws of motion apply to a uniformly accelerated motion.
Benefits

  • Especially understandable and didactically prepared description of the experiment (relevance to everyday life, etc.) including protocol questions.
  • Future-oriented teaching: Integration into digital science lessons with tablets or smartphones.
  • Increased motivation of students by using the intuitive measureAPP.
  • Increased media competence.

Tasks

  • measuring the time and thus the average speed required by the test trolley for a certain distance with the aid of two light barriers at the beginning and end of the respective distance.
  • measuring the time and thus the instantaneous speed which the aperture on the trolley needs to pass the light barrier after such a distance.
  • comparing the instantaneous and average speed.

Learning objectives
The students should qualitatively examine the differences between uniform and non-uniform movements and at the same time get to know the concept of instantaneous velocity more precisely.
