Instantaneous and average speed with Cobra SMARTsense

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.
