When observing the motion of objects, a core question is: what determines the rate of change of an object's state of motion? Newton's Second Law provides one of the most concise and profound answers in the history of physics: the acceleration of an object is directly proportional to the force acting on it and inversely proportional to its mass, and the direction of the acceleration is the same as the direction of the force. This can be expressed by the classic formula F=ma. This law quantitatively connects the three core physical quantities: force (F), mass (m), and acceleration (a). It means that to produce the same acceleration, a larger mass object requires a greater force; conversely, under the same force, a larger mass object experiences a smaller acceleration. Understanding this quantitative relationship is fundamental to understanding all dynamic phenomena, from car acceleration to rocket launches. Our interactive exhibit on "Newton's Second Law" transforms this abstract mathem
