# A 2-kg object is moving horizontally with a speed of 8 m/s. How much net force is required to keep the object moving at this speed and in this direction?

Toolbox:
• Newton's first law states that when viewed in an inertial reference frame, an object either remains at rest or continues to move at a constant velocity, unless acted upon by an external force.
An object in motion will maintain its state of motion. The presence of an unbalanced force changes the velocity of the object.
