Thanks Noah and Laura for catching an issue with the new Forces and Motion.
Just a day after we released an update, they quickly e-mailed us regarding the number of significant digits in some of the numerical readouts. PhET Developers Sam Reid, John Blanco and Chris Malley worked together to isolate and solve the problem, posting a fixed version the next day. And, we found that the “bug” also affected three other simulations, all of which have been fixed.
Thanks for reporting problems to firstname.lastname@example.org so we can get things fixed quickly!
