In physics class we will typically try to be low-tech as a default setting. White boards and dry erase markers work really well for learning. Cell phones should always be away, until the teacher directs the students to use them for specific purposes. There are various physics-specific apps that we use for lab activites.
General Physics: For reference and for additional practice, here is a physics book in PDF
Google Apps for Education
We will be using various google apps, such as google classroom and google sites. Beyond google, there are some apps for data collection that students should have.
