1 Joule in Newton Meters: Understanding the Unit of Energy
What is a Joule?
A Joule (symbol: J) is the unit of energy in the International System of Units (SI). It is defined as the energy expended when a force of one newton is applied over a displacement of one meter. In other words, it is the energy transferred when a force of one newton is applied over a distance of one meter.
What is a Newton Meter?
A Newton meter (N·m) is a unit of torque, which is a rotational force that causes an object to rotate. It is defined as the product of a force in newtons (N) and a distance in meters (m). In the context of energy, a Newton meter is equivalent to a Joule.
1 Joule in Newton Meters
So, what does 1 Joule in Newton meters mean? It means that when a force of 1 newton is applied over a distance of 1 meter, the energy transferred is equivalent to 1 Joule. This is a fundamental concept in physics, as it relates the units of energy, force, and distance.
