Newton's Third Law states that: The velocity of a particle is proportional to the vector sum of forces acting on it, and is in the direction of this vector sum. The acceleration of a particle is proportional to the vector sum of forces acting on it, and is in the direction of this vector sum. The forces of action and reaction between interacting bodies are equal in magnitude, opposite in direction, and collinear. O A particle remains at rest or continues to move with a uniform velocity if there is no unbalanced force acting on it. 7
