Here's why:
* Net force is the overall force acting on an object. It's the vector sum of all the individual forces acting on the object.
* Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
* Acceleration is the rate of change of velocity. If an object is accelerating, it's changing its velocity, which means it's either speeding up, slowing down, or changing direction.
Therefore, if a net force acts on an object, the object will accelerate in the direction of that net force.
