Physics Lab AR vs SnapLearn

Are you a curious student eager to explore deeper into the physics world? Are you a science enthusiast who wants to share your ideas with others? Are you an adventurer bounded by textbook instructions and budget limits? Are you a romantic dreaming of having your own customized galaxy? Are you a teacher who wants to use fun and interactive demonstrations in your physics lessons? Learn science by doing experiments in your virtual lab with Physics Lab. With our new AR mode, you can even bring your experiments to life! In Physics Lab, you can play with various circuit components, build your own 3D electric circuits, and see how they work in real time. With 100+ circuit components to choose from (and more coming soon), the possibilities are endless. Plus, all of our experiments are backed by science and calculated with precise numbers, so you can learn and have fun at the same time. Physics Lab is not only for students, but for teachers too! Use it to demonstrate experiments in class, and help your students learn and explore in a new way. And because it's virtual, you don't have to worry about expensive lab equipment or safety concerns. Explore with freedom - Pick from 100+ circuit components (more coming!) - Drag them from the toolbox to the virtual desk and connect them the way you like - All experiment results are backed by science and calculated in precise numbers - Design your own galaxy or load from our solar system - Electromagnetic experiments with field line visualization Better than real life - Set properties of circuit components to different figures and observe changes of behavior and stats in real time - One-click to turn what you have built into an editable circuit diagram and vice versa - No expenses on lab equipments, no worry about safety issues A lab for everyone - Teachers have been using Physics Lab to demonstrate experiments and assist teaching in class - Students, in primary or high schools, can learn science and explore freely anywhere, anytime - Kids or not, curious minds now have their own virtual lab to learn knowledge by doing experiments Whether you're a teacher, student, or just someone who loves learning about physics, Physics Lab has something for everyone.
