WebbForce measured in newtons, times distance measured in meters, gives the metric unit of work or energy, and it is called the joule. (For example if an 80 pound person climbs a flight of stairs which goes up one floor, this person will exert a force of about 360 newtons through a distance of about 4 meters, hence the person will do about 1440 joules of work.) WebbWork done (in Joules) = force (in Newtons) x distance moved (in Metres) Look at the units of the formula. Ignoring the rest of the formula, only focus on the units. This will leave you with the following: Joules = newtons x … WebbIn physics, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, for a constant force aligned with the direction of motion, the work equals the product of the force strength and the distance traveled. A force is said to do positive work if when applied it has a component in ... ethical listening means

WebbThe equation that describes the work W done on an object that moves a distance s while a force F is acting on it in the same direction as the object's movement is given by W = F s. Work is measured in joules, the force is measured in newtons, and the displacement is measured in metres. From this equation, we can conclude that 1 Nm = 1 J.
