Here's why:
* Newton's First Law of Motion (Inertia): An object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity (same speed and direction), unless acted upon by an unbalanced force.
* 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.
In summary: The net force causes the motionless object to start moving, and the object will continue to accelerate as long as the net force is present.
