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?

1 Answer

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.
Answer: 0 N
An object in motion will maintain its state of motion. The presence of an unbalanced force changes the velocity of the object.
