The concept behind "Two Trucks, same mass, one pulling other" is to demonstrate the concept of force and Newton's laws of motion. In this scenario, both trucks have the same mass, but one is able to pull the other due to the force applied by the first truck.
The mass of the trucks affects the experiment as it determines the amount of force needed to move the trucks. In this scenario, since both trucks have the same mass, the force applied by the first truck is able to overcome the resistance of the second truck and move it forward.
The role of friction in this experiment is to provide the resistance that the second truck needs to overcome in order to move forward. Friction is the force that opposes motion and in this scenario, it acts on the second truck, making it difficult to move.
This experiment relates to Newton's first law of motion, also known as the law of inertia. It states that an object will remain at rest or in uniform motion unless acted upon by an external force. In this scenario, the second truck is at rest until the first truck applies a force and moves it forward.
Yes, this experiment can be applied to real-life situations. For example, in the transportation industry, heavy trucks are often used to tow other trucks or vehicles that have broken down. The same concept of force and Newton's laws of motion apply in this scenario, where the first truck is able to pull the second truck due to the force it applies.
