{'loaded trolley bag': [0, 0, 0, 1], 'first law': [0, 0, 1, 6], 'thermodynamics': [0, 0, 0, 1], 'second law': [0, 0, 2, 6], 'more force': [0, 0, 1, 2], 'motion': [0, 0, 0, 3], 'newton': [0, 1, 0, 0]}

The correct answer is option 4: Newton`s first law of motion.

Newton`s first law of motion, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will continue in motion at a constant velocity, unless acted upon by an external force.

In the case of the loaded trolley bag, when it is at rest, it requires an external force to overcome its inertia and start it moving. This force is exerted by the person pushing or pulling the trolley bag. Once the trolley bag is in motion, it will continue moving with less force due to the momentum it has acquired.

So, it is necessary to exert more force initially to overcome the bag`s inertia and start it moving, in accordance with Newton`s first law of motion.

The other options are not applicable to this situation. The first law of thermodynamics is about the conservation of energy, not about motion. The second law of thermodynamics deals with the concept of entropy, which is not relevant in this context. Newton`s second law of motion states that the force exerted on an object is equal to its mass multiplied by its acceleration, which is not directly related to the given scenario.
