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. WebbThere are four forces involved here-- tension, the normal force, the gravitational force, and the force of kinetic friction. In finding the work done for all of these forces, the …

WebbDoing work is the act of transferring that energy. Doing work requires applying a force over some distance. The sign of the work done on an object determines if energy is … WebbWork equals Fd cosine theta, where theta is the angle between the force doing the work and the direction the trashcan is moving. There are four forces involved here-- tension, the normal force, the gravitational force, and the force of kinetic friction. In finding the work done for all of these forces, the displacement is going to be 10 meters.

WebbSound Energy, in producing noise. Example 1: Work is done against gravity when a ball is lifted to a height above the ground. In this situation, the force is the weight of the ball. The distance is the height above the ground. The weight on the ball produced by the gravitational field does work on the ball over a distance equal to the height of ...
