...direction of the force ; and the work done is measured by the product of the magnitude of the force and the distance through which the point of application moves in the direction of the force. For example, if a body be allowed to fall from any height, the work done by the earth's attraction...

...the direction of the force and the work done is measured by the product of the magnitude of the force and the distance through which the point of application moves in the direction of the force. For example, if a body be allowed to fall from any height, the work done by the earth's attraction...

...follows that s . cos 9 will denote the distance through which the place of application of the force moves in the direction of the line of action of the force. Hence JF=P.scos0. Another mode of procedure in this case is to resolve the force P into two component...

...point of application. If the force is constant in magnitude, the work done is the product of the force and the distance through which the point of application moves in the direction of the force. If W denotes the work, F the force, and s the displacement of the point of application, then...

...done. Work Done is force x distance (the work done by a force is measured by the product of the force and the distance through which the point of application moves in the direction of the force). The unit of work (which is also the unit of energy) is the dyne-centimetre or erg. The gram-centimetre...

...gram has a weight of 981 dynes. Work. — Work is measured by the product of the magnitude of a force and the distance through which the point of application moves in the direction of the force. The unit of work is called the erg, and is the amount of work done through a distance of 1 centimetre...

...in the following sentence, "When a force acts upon a body, and the point of application of the force moves in the direction of the line of action of the force, the force is said to do work on the body," what is the necessity and significance of the qualifying...
