What is the significance of a joule in physics and how is it defined in terms of energy measurement?
In physics, a joule is a unit of measurement for energy. It is defined as the amount of energy transferred or expended when a force of one newton acts over a distance of one meter. The joule is significant because it is a fundamental unit used to quantify various forms of energy, such as mechanical, thermal, and electrical energy.
Is work the rate which you expand energy?
Work is the transfer of energy that occurs when a force is applied over a distance. It is the result of energy being expended to accomplish a task or achieve a goal. In physics, work is formally defined as the product of the force applied to an object and the distance over which the force is applied.
Defined as one joule of energy expended over one second of time?
A joule / second is a watt. The watt is a unit of power. In general terms, power means energy expended, produced, or transferred, per time unit.A joule / second is a watt. The watt is a unit of power. In general terms, power means energy expended, produced, or transferred, per time unit.A joule / second is a watt. The watt is a unit of power. In general terms, power means energy expended, produced, or transferred, per time unit.A joule / second is a watt. The watt is a unit of power. In general terms, power means energy expended, produced, or transferred, per time unit.
What do you mean by one joule work?
One joule of work refers to the amount of energy expended or transferred when a force of one newton is applied over a distance of one meter in the direction of the force. It is used to measure the quantity of work done or energy consumed in various physical processes.
What does a Joule look like?
A Joule is a unit of energy, not a physical object, so it does not have a physical appearance. It is a measure of work or energy transfer, often expressed as the energy expended when a force of one newton acts over a distance of one meter.
Mechanical energy is the energy due to what?
It is the energy expended by a mechanical force acting over a distance.

Can magnets make free energy?
No. There is no known way to make energy where there was none before. According to Nöther's Theorem, if Conservation of Energy wasn't valid, that would mean that the laws of physics changed over time!

What does an over-line bar over a variable mean in physics?
It could represent a vector.

What is the significance of the root mean square pressure in the field of physics?
The root mean square pressure is important in physics because it represents the average pressure of a fluctuating signal over time. It is commonly used in the study of sound waves and other dynamic systems to quantify the overall intensity or energy of the signal.
What does conservation mean physics wise?
In physics, conservation refers to the principle that certain physical quantities, such as energy, momentum, and angular momentum, remain constant in a closed system over time. This principle is fundamental to understanding how physical systems evolve and interact with each other.
Is Power the rate at which work is done.?
true
What are the key differences between closed and open system physics?
In closed system physics, energy and matter do not enter or leave the system, while in open system physics, energy and matter can flow in and out of the system. This difference affects how the system interacts with its surroundings and how it behaves over time.
