What is Hooke’s Law in Physics
Hooke’s Law in Physics
Hooke’s Law states that the extension or compression of a spring is directly proportional to the force acting on it provided the elastic limit of the spring has not been exceeded.
Definitions:
- Joule:
It is the work done by a force of one Newton when the body is displaced one meter.
- Erg:
It is the work done by a force of one Dyne when the body is displaced one centimeter.
- Foot Pound (fT-lb):
It is the work done by a force of one pound when the body is displaced one foot.
- Force:
It is an agent that moves or tends to move or stops or tends to stop a body.
- Watt:
Watt is the unit of power that is equal to the quantity of 1 Joule work done 1 in 1 second.
Epistemological practices are not only outdated, but also degraded. But the blessing is the Internet and those who really want to know something useful turn to it. I repeat, perhaps this book and similar material will become the basis and one of the tools for those who want to draw knowledge more productively and effectively. And they, in turn, would like to believe, will be able to change our corrupt, stupid, vile and flawed society. But let’s return directly to the tools of cognition.
