A crane is lifting up a container. How would each of these affect how much work the crane does? a) Increasing the force applied to the container. Decrease the work Increase the work Not affect the work b) Increasing the height the container is lifted. Decrease the work Increase the work Not affect the work

Answer 1

a) Increasing the force applied to the container The principle of work expresses the substance of the work to be the product of the force exercised and the distance up which the force is operated (Work is equal to Force times Distance or Work = Force x Distance in physical terms). Consequently, let's assume that all other elements like distance and direction of the effect remain constant. Hence, if the force utilizing on the object intensifies, the quantity of work implemented by the force will openly improve given this equation. 【Answer】: Increase the work b) Increasing the height the container is lifted. The work produced in lifting a particular thing relies profoundly on three aspects, the strength of the force applied, the track of the strength, and the distance of the movement while the force is asserted. The distance over which the force is expended has a straightforward effect on the quantity of work performed if all else remains consistent (force and direction). Therefore if we are lifting a weight (container in this case), the higher we lift the item through the identical applied force, the greater energy required to finish this function or in easier words, the work executed on the item has increased. 【Answer】: Increase the work
