I hate to WORK

This has been a not bad weekend, especially since theres only one more week of school before spring break! Physics is everywhere and i'm always doing something that refers to the concepts of physics. Work has a very specific meaning and it isn't quite the same as what you all may think. You are not doing work if you are just holding something off the ground, perhaps weights, even if you can feel the burn in your muscles. But you are doing work while you are actually lifting the weight up and down because you're changing the energy by moving. Work reguires two things...force and motion in direction of force (distance). The equation for work is W=F x d. Positive work adds energy to a system and negative work removes energy from the system. Total work done to a system equals the change in energy for the system. Any object you pick up, you are doing work to it. Even if its just lifting a pencil, you're still doing work to it even if you can't actually feel it. In this picture, i am lifting a table but i'm just holding it which means i'm not doing work. But during the time i bent down to pick it up and lift it, i was doing work.
