Can I create interactive physics simulation with unity3D?

I am teaching secondary school physics and I want to create some simulations, which will satisfy my point of you. Do you recommend to create sims via Unity3D or it is better to try with html5?
Interactive features must be included, like scroll bars, where the parameters of the physics’ problem will be defined by the user.
Thank you,

You totally can! Making it in Unity would probably be easier than making it from scratch in html5.

Check out Unity’s tutorial page on physics, both 2D and 3D.

If you want an interactive user interface, check out Unity’s tutorial page on UI, or the documentation on UI.
