There is a friction force of 10 Newtons between a box and a table top. In order to move the box at a constant velocity, you would have to supply a force of:

  1. 10 Netwons

  2. > 10 Newtons

  3. < 10 Newtons

  4. Nonsense! No force is required to move the box

A Correct answer
Explanation

To move at constant velocity (zero acceleration), the applied force must exactly balance the friction force. Since friction = 10 N, the applied force must also be 10 N to achieve net force = 0 (Newton's First Law).
