This simulation is an attempt to address the misconception of an "upward throwing force" that beginning learners have. To rationalise that the ball will fall under gravity, the most common semi-physical explanation is "upward throwing force on the ball will gradually disappear until the ball reaches the top".

This simulation allows learners to adjust the upward force on the model ball to test out their hypothesis.

(Note: require Xuggle to play video)

  • Please feel free to post your ideas about how to use the simulation for better teaching and learning.
  • Post questions to be asked to help students to think, to explore.
  • Upload worksheets as attached files to share with more users.
Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!

the error at t = dt appears to be random
i not sure why it happens

attached is my attempt to debug the bug LeeTL reported via email
