Free fall with Cobra SMARTsense

Principle

The mass of the steel ball generates a constant rectified force in the gravitational field of the earth, which causes the ball to move uniformly accelerated. Frictional effects in air are negligible in this experiment, as is the buoyancy of the ball by the surrounding air.
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

• The students let a steel ball fall freely and measure the fall times for different fall heights by means of two light barriers and examine the measurement data according to laws that combine the two quantities fall distance and fall time.

Learning objectives
In this experiment, the students are to determine the acceleration due to gravity experimentally and recognize that free fall is a
represents uniformly accelerated motion.
