Hello, this is my first post.
Some years back i read a book about einstein works. Among many things in the book, i read about his 'modified' Newton's equation of motion (F=ma). Sadly, i had lost the book and can't recall the equation. All i can remember is it says that the einstein's equation should be used when a body is moving at close to or higher than speed of light. The F=ma is still correct for motions slower than that.
I hope someone can tell me what is the equation.
Thanks.
p/s: English is not my 1st language, so i hope everbody can understand what I'm trying to say here.
