प्रश्न
To move a loaded trolley we have to ______ it.
उत्तर
To move a loaded trolley, we have to push it.
Explanation:
Pushing or pulling creates a force on the tram that overcomes its inertia, allowing it to move from its fixed state. This movement also aids in overcoming friction between the trolley's wheels and the surface it travels on. The weight of the load and the surface's frictional characteristics determine the required force.
