## What is PE.Mech?

This app is aimed at mechanics part and includes 11 experiments 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.
