[NFB-Science] Gravity experiments

It is not at all calculus. Calculus involves rates or change, or derivatives. You can use calculus to write this equation, but it is not necessary. It is algebra at best, because algebra involves replacing numbers with symbols to represent patterns. But you don’t need any prior learning or experience beyond basic arithmetic to do this. All you have to do is plug in the numbers you want for the symbols that represent them. X is position. A is acceleration. T is time. We know that the acceleration on earth is six times what it is on the moon. And we can choose the fixed time or height as we see fit. Choose the time, and it should give you how far the object falls. Choose a distance, and it gives you how long the object takes to fall that far. So it’s algebra at its most basic. But absolutely not calculus at this stage.

> Since I’m going to take math in the winter for my own journey as a college student, this formula will help me out in practicing math. I don’t know if the younger students will be ready for this equation. As I read it, the equation looks like it might be advanced algebra or calculus. I know that schools are teaching algebra to younger students than they did in the past. But I don’t know how many of our students will be ready for this one. We get students from 4 all the way to 17 years old in our BELL program in Oregon. However, I’ll keep it around anyway for the mathamitions of the class room. Besides, I’ll want to give it a try myself just to find out if I get the correct answer or as close to it as the math itself allows because even math is not totally exzact, particularly with circles. I’ve even heard of unsolved math problems. However, this is a good tester even for me.
