Net force should be the answer.

Explanation: Its not speed because speed can be constant, its not velocity because velocity can be constant as well. Plus velocity is just speed with direction. And its not inertia because inertia is an objects capacity to maintain its state of motion (at rest or in uniform motion)

Hope this helps! :)

Net force causes an acceleration or change in the motion of an object.

Newton's first law of motion states that an object in a state of rest or uniform motion in a straight line, will continue in that state unless acted upon by an external force.

The second law states that the force applied to an object is directly proportional to the product of mass and acceleration of the object. The object tends to move in the direction of the net force.

Acceleration is defined the change in the velocity per change in the time of motion of the object.

where;

  • Δv is the change in velocity.

Thus, we can conclude that net force causes an acceleration or change in the motion of an object.
