Laws of motion of uniformly accelerated motion with Cobra SMARTsense

Principle
On the inclined plane, the measuring carriage experiences a constant slope downforce resulting from the earth's gravitational field, which accelerates the carriage evenly.
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

• In the first part of the experiment, the pupils let the experimental trolley roll down an inclined plane and measure the travel times the trolley needs for different distances, whereby a light barrier remains unchanged at the starting point of the trolley.
• In the second part of the experiment, the pupils measure the shadowing times of the rear light barrier for the various end points of the route. The instantaneous speeds are calculated from this.

Learning objectives
In this experiment, the students are to investigate acceleration using the example of a uniformly accelerated movement and to record the laws of motion in the form of diagrams.
