Principle

Acceleration is one of the basic concepts of the theory of motion. It indicates how fast an object changes its speed and is measured in the unit m/s². The concept of acceleration is based on the average acceleration as the quotient of the change in speed in a given period of time.

Velocity is one of the basic concepts of the theory of motion. It indicates how fast an object is moving in space and is measured in the unit meter per second. The concept of instantaneous velocity is based on the average velocity as the quotient of the change in position in a given period of time.

Benefits

  • Free measuring software DigiCartAPP for all mobile devices and all operating systems (Windows, Android, iOS).
  • Especially understandable and didactically prepared test description can be called up in the DigiCartAPP.
  • Complete evaluation function for the measured data directly in the DigiCartAPP.
  • DigiCart:
    • Long-life lithium-ion batteries with charge protection function
    • Transmission of measurement data via Bluetooth 4.0
    • Integrated sensors (force, speed, acceleration and position sensor)
  • Digital measured value acquisition:
    • Future-oriented teaching: Integration into digital science lessons with tablets or smartphones.
    • Increased student motivation by using the intuitive DigiCartAPP.
    • Increase of media competence.

Tasks

1) Record several speed-time diagrams via the app. Select a measuring range and let it calculate the acceleration for the recorded curves.

2) Use the velocity-time diagram to determine the position-time diagram of the movement.

Learning Objectives

In this experiment the students learn about the physical meaning of acceleration. They also learn how to obtain the local time diagram from a velocity-time diagram.
