Here's why:
* Newton's Second Law of Motion: 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. Mathematically, this is represented as: F = ma (Force = mass x acceleration).
* Acceleration implies a change in velocity: Acceleration means the object's velocity is changing – either in magnitude (speed) or direction, or both.
* Zero net force means no acceleration: If the net force acting on an object is zero, it means all the forces acting on it cancel each other out. This results in a balanced force, leading to no change in velocity – meaning the object remains at rest or continues moving at a constant velocity.
In summary: If an object is accelerating, it means there is a net force acting on it, and that force cannot be zero.
