Answer:
Both positive work and negative work have meaning: Positive work follows when the force has a component parallel to the displacement. Positive work adds energy to a system. Negative work follows when the force has a component opposite or against the displacement.
Newton's first law of motion predicts the action of objects for which all existing forces are balanced. The first law, also referred to as the law of inertia, states that if the forces acting upon an object are balanced, the acceleration of that object will be 0 m/s/s. Objects at equilibrium will not accelerate. According to the law, an object will only accelerate if there is an unbalanced force acting upon it. The presence of an unbalanced force will change its speed, its direction, or both its speed and direction. All forces retaining to this law are related to inbalance
