Spring Quiz...

A quiz about springs for students:

• A hanging spring has a mass attached. The system then reaches equilibrium. The mass is pulled down and then released. The process is animated; at each stage students are asked to answer questions about kinematics (position, speed, acceleration), forces (weight and spring) and energy (gravitational potential, kinetic, spring potential, and conservation).

• Each question of the 34 questions allows for three attempts and one hint, and the app keeps track of the score. If a student fails to provide a correct answer (within 10% of the true answer) after three attempts, the answer is provided to the student.

• Each student will see a different spring... different spring constant, length, and extension, and a different mass. If the student resets the app, different values will also be presented. 

This simulation opens in all recent popular computer browsers (Chrome, Firefox, Safari, Edge, Opera) and Chromebooks. SpringQuiz does work on iPads and similar, not so well on phones.
