vastumõju
Vastumõju refers to a phenomenon where a system or process experiences a reaction or counteraction in response to an initial force or action. This concept is applicable across various scientific and philosophical domains, often describing a balancing or opposing influence. In physics, for instance, Newton's third law of motion states that for every action, there is an equal and opposite reaction, which is a fundamental example of vastumõju. This means that when one object exerts a force on another, the second object simultaneously exerts a force of equal magnitude and opposite direction back on the first.
The principle of vastumõju can also be observed in social and political contexts. For example, a government
