The unit you should use for work done and energy is the joule (J) which is indeed the same as the newton metre (N m). There is another physical quantity which is the product of force and distance and that is torque or moment of a force. The unit you should use for torque is the newton metre (Nm) and not the joule.
What is the unit value of work?
unit of work is Joule. Work done when a force of 1 Newton displaces the body through a distance of 1 metre in the direction of force.
Is NM unit of work?
One newton-metre is the torque resulting from a force of one newton applied perpendicularly to the end of a moment arm that is one metre long. The unit is also used less commonly as a unit of work, or energy, in which case it is equivalent to the more common and standard SI unit of energy, the joule.
Is NM SI unit of work?
Newton metre (N m) is a unit of work but not its SI unit.
What is the unit of work in terms of basic units?
Joule is SI unit of work or energy. As work = force xx distance.
What is work class 11?
Work is said to be done when a force applied on the body displaces the body through a certain distance in the direction of applied force. It is measured by the product of the force and the distance moved in the direction of the force, i.e., W = F-S. •
What unit is nm?
The nanometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: nm) or nanometer (American spelling) is a unit of length in the metric system, equal to one billionth (short scale) of a metre (0.000000001 m).
What is meant by 1 joule of work?
1 J is the amount of work done by a force of 1 N on an object that displaces it through a distance of 1 m in the direction of the applied force. 1 J = 1 N x 1 m.
Is eV unit of work?
The work done on the charge is given by the charge times the voltage difference, therefore the work W on electron is: W = qV = (1.6 x 10-19 C) x (1 J/C) = 1.6 x 10-19 J. Electronvolt (unit: eV). Electronvolts are a traditional unit of energy, particularly in atomic and nuclear physics.
What unit is N m2?
Newtons/Square Meter is a unit that shows how the pascal unit is derived from other SI units. Pressure is defined as Force/Area and the SI unit for Force is newtons (N) and the SI unit for Area is Sq Meters (m²).
What is the unit of work or energy?
The SI unit of energy/work is the joule (J), named for English physicist James Prescott Joule (1818 – 1889).
