1 Joule is Equal to 1 Newton Meter: Understanding Energy and Force
What is a Joule?
In the field of physics, a joule (J) is a unit of energy. It is a derived unit in the International System of Units (SI) and is defined as the energy expended when a force of 1 newton is applied over a distance of 1 meter. In other words, a joule is a measure of the energy required to perform a specific amount of work.
What is a Newton Meter?
A newton meter (N·m) is a unit of torque, which is a measure of rotational force. In the context of physics, a newton meter is equivalent to the force of 1 newton applied over a distance of 1 meter in a direction perpendicular to the line of action of the force.
The Equation: 1 Joule = 1 Newton Meter
The key takeaway from this article is that 1 joule is equal to 1 newton meter. This means that the energy expended in applying a force of 1 newton over a distance of 1 meter is equivalent to 1 joule.
Mathematically, this can be represented as:
1 J = 1 N·m
This equation highlights the fundamental relationship between energy (joules) and force (newtons) in physics.
