reaktsioonijõudu
Reaktsioonijõud is a fundamental concept in physics, specifically within Newton's laws of motion. It describes the force that is equal in magnitude and opposite in direction to the action force. This principle is often referred to as Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
When one object exerts a force on a second object, the second object simultaneously exerts a force
The concept of reaction force is essential for understanding a wide range of phenomena, from the propulsion
