This app is aimed at mechanics part and includes 11 experiments [need full version] about: kinematics, Newton's laws of motion, work and energy, momentum and impulse, periodic motion etc. It has some features: 1. You can set ideal conditions, for example: friction=0, air resistance=0, any gravity acceleration; 2. Show changing physical values by function diagram, free body diagram, energy diagram etc in real time to compensate for the lack of real experiments; 3. You can set any reasonable parameters to see different results, and calculate them by the descriptions to test your understanding; 4. Suitable for use in high school and college students; I hope this app can help you in your physics learning.
