Exactly - as I also discussed in my posts #13, #17 and #25.

You don't know a priori that pulling the masses together and separately will result in the same acceleration, which is why you do the experiment.
What you are trying to demonstrate in Newton's law is not the constant of proportionality (since that would be units-dependent) but the fact that a direct (linear) proportionality exists at all.
The Second Law of Motion, also known as the Law of Acceleration, states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In this experiment, we can observe how the acceleration of the object changes as we manipulate the net force and mass, thus proving the Second Law.
The experimental setup will involve a cart or object with a known mass, a force sensor to measure the net force applied, and a motion sensor to measure the acceleration of the object. The experiment will involve changing the net force acting on the object while keeping its mass constant, and vice versa, to observe the relationship between force, mass, and acceleration.
No, Newton's Second Law cannot be proven through one experiment alone. It is a fundamental law of physics that has been extensively tested and proven through various experiments and observations. This experiment will provide evidence and support for the Second Law, but it cannot be proven solely through one experiment.
To ensure the accuracy of the results, we must follow proper experimental procedures and use precise and calibrated equipment. It is also important to repeat the experiment multiple times and take an average of the results to minimize errors. Additionally, we must consider and control any external factors that could affect the results, such as friction or air resistance.
Proving Newton's Second Law has significant implications in the field of physics and engineering. It helps us understand the relationship between force, mass, and acceleration, which is crucial in designing and building structures and machines. It also forms the basis for other laws and principles, such as the Law of Conservation of Momentum and the Law of Universal Gravitation.
