Which Newton's law states that an unbalance of force on a body tends to produce acceleration in the direction of the force?

The Second Law of Motion is key in understanding the relationship between force and acceleration in a body. This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In a mathematical form, this is expressed as F = ma, where F is the force applied, m is the mass of the object, and a is the acceleration produced.

This principle is fundamental in the context of gas turbine engines, where forces are constantly acting on various components. When a force is applied (e.g., from combustion gases expanding and producing thrust), the engine and its components accelerate in response to that force. This relationship underscores the importance of balancing forces within the engine design to ensure optimal performance and efficiency.

Other options refer to different concepts that do not directly relate to the relationship between force and acceleration. The First Law of Motion pertains to inertia and the tendency of objects to remain at rest or in uniform motion unless acted upon by a force. The Third Law of Motion, known for stating that for every action there is an equal and opposite reaction, describes interaction forces between two bodies but does not specifically address the relationship between unbalanced forces and acceleration. The Law of Universal Gravitation, while explaining the attraction between
