The standard unit of work is the joule (J) which is also written as N.m as Newton (N) is the SI unit of force and meter (m) is the SI unit of displacement.

Which of the following is a unit of work?

Detailed Solution

The SI unit of work is the joule (J).

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 joule A unit of work?

joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds.

Which is not a unit of work?

Volt is not a unit of work.

Which unit is newton?

newton, absolute unit of force in the International System of Units (SI units), abbreviated N. It is defined as that force necessary to provide a mass of one kilogram with an acceleration of one metre per second per second.

What is meant by 1 joule of work?

1 Joule is defined as the work done when a force of 1 N produces a displacement of 1 m in the direction of the applied force.

What is the unit of work or energy?

The standard unit used to measure energy and work done in physics is the joule, which has the symbol J. In mechanics, 1 joule is the energy transferred when a force of 1 Newton is applied to an object and moves it through a distance of 1 meter.
