We often find in the relativity chapters of Physics and Mathematics books the statement that "the mass of an object increases as its speed approaches the speed of light". Is this correct, does the mass of an object actually increase, or is this a means of describing what is happening to a very rapidly moving object in Einstein's four dimensional space-time in terms of familiar quantities using Newton's laws of motion?
Physics and Mathematics
What are the concepts in Physics and Mathematics that students find difficult? In this blog I will post tutorial points that I hope will stimulate thinking and so broaden the knowledge and understanding of students allowing them to write thorough examination responses. Tutorial sheets, structured from a student's point of view, will be posted on the HSC, IB and university level topics of Relativity, Electromagnetism, Mechanics, Quantum Physics and Calculus. The overall purpose of these pages is to encourage and promote learning in Physics and Mathematics and so open new horizons in learning.
