Definition For Work In Science
In physical science such as physics and chemistry work is force multiplied by distance.
Definition for work in science. For example if you lift a 5 n load 10 m in the air the amount of work done is. If the force varies e g. Though both force and displacement are vector quantities work has no direction due to the nature of a scalar product or dot product in vector mathematics. Compressing a spring we need to use calculus to find the work done.
Work occurs if there is movement in the direction of the force. The si unit of work is the joule j. In the case of a constant force work is the scalar product of the force acting on an object and the displacement caused by that force. And then the most general definition of work can be formulated as follows.
Work is an interesting concept because the same amount of work can be done in different situations. In physics work is defined as a force causing the movement or displacement of an object. 5 n 10 m or. Work in physics measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement if the force is constant work may be computed by multiplying the length of the path by the component of the force acting along the path.
