I got wondering about the difference between weight and mass. Well, there are probably a lot of differences. Weight is what my scales show me and mass is what is said in a church. . . OK, that isn't the mass I am talking about. Well let me think a minute . . . OK, mass is what causes you to get knocked down when a huge football linebacker runs into you. Weight can only be measured in the presence of gravity, but mass can exists in space far from any other objects or planets.
Another way to look at it is that a balloon full of helium rises in the air. Therefore, it has no weight but it still has mass. Yes, I know that is not a perfect example, but it is the best one I have. So, you disagree? OK, you measure the weight of that rising balloon!! So, if someone tells you that you should loose weight, just go into the ocean and float around on your back and tell them to weigh you now. In this case, your weight is transfered by the water and spread over ocean floor. So, does that mean that the floating man is weightless? It may or may not but he still has mass. Weight is only a measurement where as mass is a constant no matter where you are in the universe, except maybe in or near a black hole where the laws of physics, as we know them, may be different. Now I hope you don't have any excess weight on your shoulders and I want you to have a great day, you hear?
