Final answer:
In the real world, work is greater than in the ideal world because there are additional forces like friction and air resistance that must be overcome, requiring extra force and increasing the amount of work done.
Step-by-step explanation:
The amount of work required to perform a task in the real world is often greater than the work calculated in an ideal, frictionless scenario. This is because in the real world, additional forces such as friction, air resistance, and inefficiencies in machines require extra force to overcome, leading to an increase in the amount of work done. For example, when you push a box across the floor, you must do enough work to overcome not only the box's inertia but also the friction between the box and the floor. In contrast, the ideal world presented in physics problems usually ignores these extra forces, resulting in a lower amount of work needed for the same task.
